Mining Industry is facing a rough weather. It has been under scrutiny for quite some time. No opportunity is lost by some vested agencies in attacking the mining activity either due to occurrence of social claims, corruption or its very nature of impacting the social and natural environment. There appeared many breaking news in print and electronic media on illegal mining, mining related claims, damages to the environment, closure of mines, mining scams, coal blocks allotment scams and so on, the list is long. It has imparted a very shabby picture on mining Industry, which happens to be a core industry for development. The negative perception attracts attention quickly than the positive one. Anyone may think when so much adversity is associated with mining when doing no good to the society - instead creates social chaos and is not friendly to ecological heritage, why mining should be undertaken at all.

A layman does not understand the connectivity of mining with the style of living of the modern man. Even the high profile people, be in Government, policy making body or elsewhere, although acknowledge the necessities of minerals in this industrial world, do air their clumsy remarks that go against the mining institution also.

Many countries in the world made fortunes by converting their mineral wealth into national wealth. Leaving aside Australia and Canada which are developed nations consequent to exploiting their mineral resources, the poor countries like Ghana, Botswana. Peru, Chile and others in Africa and Latin America have exploited their resources wealth, utilized the mining income for the social wellbeing of the country and reduced their poverty level varying from 62 to 90%.

Indian mineral sector started losing its credibility on social and environmental grounds due to growing awareness of the local population of their rights and expectations from the mining activities. It is a general apprehension that the mining earns huge profit at the cost of forest and environments, but its income is not percolating to improve the life of poor surroundings. Associated claims, murders, bribery and scams happened in preceding years adding more fuels to tarnish the image of an industry which has tremendous potential for growth and development.

It is to be understood that the long geological processes have manifestated the minerals in the ground for our use and we are bestowed with intelligence to responsibly extract them for the benefit of human society. “Not in my backyard” attitude of elite people should be condemned. Strict laws and ground implementation are the solutions to govern the mining activities. It will prevent the greed of the people from destroying the natural environment and will also protect the right of miner from the radical anti mining groups.

iron ore deMand WiLL doubLe bY 2030: rMG/ MininGThe global demand for iron ore will double over the next 18 years driven primarily by China’s and India’s appetite for steelmaking.

According to a recent report by Raw Materials Group, iron ore demand is set to double to around 3.5 billion tonne per by 2030.

RMG says that while India and China will continue to drive the market for iron ore by purchasing vast quantities of the material crucial for steel making, both countries will have their challenges, with China facing hurdles particularly in Africa over their quest to control 50% of imports and Indian

steelmakers and iron ore miners clashing over how much iron ore should be exported to maintain the thriving domestic steel industry.

WorLd’S LarGeSt CoaL CoMPanY MuSCLinG in on WorLd’S LarGeSt MetaLLurGiCaL dePoSitShenhua Energy, China’s largest coal producer, expects to restart talks with the Mongolian government over the Tavan Tolgoi Coal Field after June elections.

The Tavan Tolgoi deposit – mined since the 60s – in the South Gobi desert is the world’s largest high-quality coking coal used in steel making.

Earlier in March, Mongolia stopped all talks with international miners on developing the western Tsankhi block of Tavan Tolgoi which on its own holds 1.2 billion tonne after a shambolic bidding process that stretches back to 2007.

“Shenhua is the most competitive bidder for the project given its technology, transport infrastructure, access to the Chinese market and the backing of the Chinese government," Shenhua CEO Ling Wen told reporters.

Shenhua is the world’s largest coal company with 1,67,000 employees and 53 operating mines producing 282 million tonne per year. The state-owned firm’s financial results showed net profits of $7.2 billion for 2011.

High quality metallurgical coal has been trading at around $220-$235 per tonne level since January 2012, down from record levels of $330/tonne last year and quality deposits have become harder to come by.

CoaL india’S 180 MininG ProJeCtS aWaitinG GoVernMent aPProVaL.As many as 180 proposals of Coal India (CIL) are awaiting forest clearances from the Centre and the State governments, Parliament was informed.

“At present, 180 forestry proposals of different subsidy companies of CIL involving an area of 28,484.49-ha forest land are awaiting clearances at various levels" as informed me “Minister of State for Coal Prakashbapu Patil in Rajya Sabha informed the Parliament.

Out of 180 proposals, 131 are awaiting Stage-1 (in-principle) level approval and 49 are awaiting final or Stage-II approvals, he said, adding that 70 applications are also waiting for environmental clearances.

MEJ, Vol. 13, No. 10 May 20128

In January Company’s then Chairman N C Jha said that 168 such proposals, including 67 new projects of the CIL are awaiting clearances.

Patil also said that Coal India’s initial projected production for the ongoing fiscal, estimated at 520 million tonne, had been curtailed in the mid-term review of the current Plan due to “considerable delay” in obtaining forest and environment clearances and land acquisition issues.

He added that imposition of moratorium on new and expansion projects in areas having Comprehensive Environmental Pollution Index (CEPI) above 70, had further delayed Coal India’s projects and the production target for current year was again revised to 447 MT for the ongoing fiscal.

CoKinG CoaL deMand Seen at 115 Mt/Y bY 2015 aS aSian ConSuMPtion riSeSDemand for coking coal will have increased by 115 million tonne a year by 2015 as a result of increased consumption from Asia predicts consulting engineering and project Management Company Hatch Africa Director for coal, Gerrit Lok.

He asserts that the global crude steel industry is growing at a compound annual growth rate (CAGR) of 5.2% owing primarily to increases in demand from China and India.

In addition, forecasts suggest that demand for coking coal will continue to be driven by the Asia region, while supply will depend primarily on production from Australia and North America.

The bulk of global crude steel is produced through either blast furnace or basic oxygen furnace technologies, while supply will depend primarily on consumer of coking coal – it grew its market share from 58% to 73% between 2000 and 2012.

“As a key ingredient in the production of crude steel from blast furnaces, global coking coal production has grown by 5.5% while coking coal consumption has, over the same period, increased by 5.1%. As a result, the overall production of coking coal is above the amount required to sustain the forecast demand”, Explains Lok.

Indian coking coal imports are expected to increase to 43 million tonne by 2015 from 30 million tonne in 2010, as a result of the country’s increase in crude steel production.

Lok expects crude steel production in India to grow at a CAGR of 8.1%, resulting in the associated coking coal import demand growing at a CAGR of 7.5% between 2009 and 2015.

Meanwhile, Chinese coking coal imports are expected to increase; however, this will depend on crude steel production, domestic coking coal production and production costs.

“Chinese crude steel production has grown at a CAGAR of 14.9% from 151.6 million tonne in 2001 to 607.6 million tonne in 2010, which is tremendous growth. However, it is (believed) that the intensity of crude steel production in China has peaked, and it is expected that steel consumption will increase at an average of 3% between 2010 and 2015.” explains Lok.

Lok believes that, globally, long-term growth in crude steel production looks promising owing to the expected production of an additional 300 million tonne of crude steel every year by 2015, which will increase the demand for coking coal.

“This increase in demand ultimately leads to the question of supply,” he says.

Lok says there is the possibility of a coking coal deficit from 2015 onwards, although the supply of coking coal should remain dependent on exports from Australia, with further export opportunities originating from Mozambique, Indonesia, Mongolia, Russia and North America.

“The seaborne export of coking coal will still depend on Australia. Despite this country being the biggest exporter of seaborne coking coal, with 64% of world exports, it is expected that its exports of coking coal will increase further to 192 million tonne by 2015,” he points out.

He adds that there is the possibility of an increase in export levels from the US, considering the high cash cost of its mines, which could ultimately provide an incentive for the country’s mines to provide additional supply of coking coal to the market in the long term.

Mozambique, in particular, has ambitious plans to export more than 100 million tonne a year, despite the country’s infrastructural bottlenecks which remain a problem.

“There is a disconnection between the pace of mine development and that of the infrastructure needed to transport the coking coal and export it. As a result, Mozambique remains a long-term solution to the tight coking market, with a likely potential for exporting 12 million tonne a year of coking coal by 2015,” says Lok.

Mongolia has the potential to export 15 million tonne a year of coking coal in the near future, although large scale investment is needed to develop the country’s Tavan Talgoi deposit as well as railway links.

MEJ, Vol. 13, No. 10 May 20129

“The Tavan Tolgoi deposit is one of the world’s largest undeveloped coking coal deposits, with an estimated reserve of 2-6 billion tonne,” he says.

The annual output, which could reach up to five million tonne a year, would primarily target the Chinese market and the deposit’s export potential will ultimately be determined by the rail links to China.

“According to a World Bank report, Tavan Tolgoi’s output would be sufficient to justify building a railway line into China. The cheapest route to export coal would be via the Chinese port of Huanghua, via Baotou, for about $56.5/t, while exporting via the Russian port of Vostochnoy would cost about $125/t,” Lok asserts.

He adds that, regardless of the routing, exports from Tavan Tolgoi will displace a percentage of the Australian exports to China.

Meanwhile, Russia has the potential to export coking coal from its Elga basin, but this depends on the extent of investment into its port infrastructure.

indian CoaL Miner and PoWer ProduCer in JVIndia’s largest power producer NTPC Limited has offered to partner Singareni Collieries Company Limited (SCCL) to develop coal mines in southern India.

During a recent meeting between NTPC chairperson Arup Roy Chowdary and SCCL chairperson S. Narsingrao, the power producer conveyed its willingness to invest in joint ventures (JVs) to develop coal blocks with supply linkages to NTPC’s thermal power plants in the region.

The government - owned SCCL is the second largest Indian coal miner after Coal India Limited (CIL) and operates 13 open cast and 42 underground mines in the Godavari River Valley, in southern India, producing 52-million tons a year of coal. The Godavari River Valley basin is estimated to have a coal reserve of 8.79 billion tons along a single stretch of 350 km.

NTPC’s proposal to team up with a standalone miner was aimed at faster access to coal assets following its own tardy progress in developing coal blocks allotted to it. Last year, the Coal Ministry cancelled the company’s allocation of reserves of Chatti Bariatu, Chatti Bariatu South, Keramdari, Brahmani and Chichiro Patsimal for failure to develop the blocks within the stipulated time frame.

NTPC with an installed capacity of 36 014 MW has been hit by coal supply shortage.

During 2011/12, the company’s total coal requirement was 164 million tonne with CIL supplying 114 million tonne and

the balance met through imports. The company currently operates 15 thermal power plants across the country.

Meanwhile, SCCL has firmed up a capital expenditure of $683-million over the next five years to increase its coal production to 57 million tonne a year from current levels of 52 million.

doMeStiC CoaL ProduCtion to inCreaSe to 795 Mt bY 2016-17The country’s coal production is projected to increase by over 43 per cent to 795 million tonne (MT) by 2016-17 financial year, from an estimated 554 MT in the current fiscal.

The “projection is based on obtaining necessary clearances and availability of requisite land for coal mining”, Minister of State for Coal Pratik Prakashbapu Patil said in the Rajya Sabha.

“As per the draft report of the working group on coal and lignite set up for formulation of 12th Five Year Plan, the indigenous availability of coal is projected to increase from 554 MT in2011-12 to 795 MT in 2016-17, provided requisite land is available for coal mining and all other clearances are obtained in time,” he said.

Of this, Coal India Ltd’s (CIL) contribution is expected to increase by over 39 percent to 615 MT by 2016-17 against the revised estimates of 440 MT for the current financial year, he added.

inVeStMentS auStraLia, Canada, CHiLe, braZiL and MeXiCo tHe toP fiVe MininG ProJeCtS’ deStinationIn its annual ranking of countries in terms of political risks for mining investment, the mineral industry advisory firm Behre Dolbear has ranked Australia, Canada, Chile, Brazil and Mexico as the top five nations to locate mining projects.

The five lowest-scoring nations were Russia, Bolivia, Democratic Republic of Congo and Kazakhstan with Papua and New Guinea being the worst in terms of political risk for mining projects.

Surprisingly, the United States was the worst ranked nation in terms of mining permit delays by the Denver-based mining business consultant.

For the study, 25 nations were ranked on seven criteria including economic system, political system, degree of social issues affecting mining, delays in receiving permits, degree of corruption, stability of the country’s currency and the competitiveness of the nation’s tax policy.

Due to their inherently low ranking, the firm decided not to rank Venezuela and Zimbabwe on the list, despite significant mineral wealth both contain.

“Behre Dolbear advises clients to exercise notable caution when considering investments in these countries. The political and social situation in Zimbabwe continues to warrant exceptional consideration in risk mitigation while in Venezuela, Hugo Chavez’s nationalization of gold mines and other mineral resource assets severely limit investment return potential. Significant political reform must occur in both countries prior to the restoration of investor confidence.

In the report, Behre Dolbear noted State-owned enterprises (SOE) and sovereign wealth funds (China, Korea, Russia, India, Singapore, Saudi Arabica, and elsewhere) are continuing to invest in mineral resource development and production as their parent countries consume more mineral products correlated to economic growth.

CorPorate neWStata GrouP LooKinG to Partner WitH SoutH afriCan CoaL MinerThe Tata Group, India’s largest conglomerate, is said to be investigating a joint venture with South African coal producer-Increase Coal (Pty) Ltd.

Hindu Business Line reports that the proposed tie-up could produce about 9 million tonne of metallurgical coal per annum destined for India’s steel mills, or exported to Corus, a subsidiary of Tata Steel,

Increase Coals’s mine is about 500 kilometres from Richards Bay Coal Terminal in South Africa, which is the world’s largest coal export terminal with a capacity of 91 million tonnes per annum. Tata Steel has two collieries in West Bokaro and Jharia, about 150kilometers from the steel plant at Jamshedpur, notes Hindu Business Line.

Hit by shortages, Indian steel companies are clamouring for ready supplies of metallurgical coal used in steel making.

Back in November, Tata Steel was reportedly making a bid for Queensland based New Hope Corp. But in March, New Hope said it would not put itself up for auction for more than $45 billion after a five-month sale process failed to come up with a deal. Other potential suitors include Korean consortium Aditya Birla and Shenua Group of China.

taXeSindia WorKinG on MininG taXAn Indian government task force comprising representatives of the Steel, Mines and Environment & Forest Ministries was working on modalities for the levy of Forest Development Tax (FDT) on minerals mined from forest regions.

The FDT proposal comes in the wake of the demand raised by several provinces like Orissa for the levy of a mineral resource rent tax (MRRT) with a minimum of 50% on super profits earned by miners.

The Orissa government had suggested modelling an MRRT along the lines of new mining tax laws in Australia.

“However, the objective of the FDT would not be that of an MRRT, since defining ‘Super Profits’ under Indian mining conditions would be difficult within the ambit of existing laws”, Mines Ministry officials said.

Working out the basis for calculation of the FDT had proved challenging. According to one mechanism under consideration, the levy would be calculated on the sale value of the mineral extracted. However, while the Indian Bureau of Mines periodically announces the sale value of minerals like iron ore, chromite and manganese, no standardised sale value was available for several other minerals like bauxite and copper.

“A mechanism to collate data and determine the sale value of these minerals would have to be completed first”, an official said.

Another vexatious issue facing the task force was the end-use of the fund accumulated through the FDT. One option tentatively being considered was to have the Ministry of Environment and Forests to administer the fund, but Ministry officials were worried that this could run into opposition from provincial states, which would insist on access to the fund, since governance of forest areas falls within the purview of provincial laws.

Under the Mines and Minerals Development and Regulation Bill currently before India’s Parliament, it would be mandatory for mining companies to share 26% of profits and 100% equivalent to royalty payments with the local population. These funds were to be allocated to district level authority for spending on project-affected families.

The task force has argued that district level authorities would not have the capabilities for development, redevelopment or maintenance of forests spanning vast geographies and often cutting across provincial borders.

The task force has referred the issue to the Law Ministry, since provincial government Forests Departments were not permitted to levy any tax under existing mining and mineral laws.

Moreover, given the rampant illegal mining across the country, it would be daunting to monitor, if minerals were being extracted from either forest or nonforest areas, since

a single reserve often cuts across both types of land. Mines Ministry officials said it was beyond even IBM’s capabilities to monitor every ton of mineral extracted from each mine.

1.0 introduCtionAir pollution is a major environmental problem across the globe. Various studies by economists and epidemiologists have tried to understand the relationship between health and air pollution and other relevant factors. The effects of air pollution on health are very complex as there are many different pollutants and their individual effects vary from one to the other. Despite this, the World Health Organization (WHO) estimates that every year 800,000 people die prematurely from lung cancer, cardiovascular and respiratory diseases caused by outdoor pollution. Other adverse health effects include increased incidence of chronic bronchitis and acute respiratory illness, exacerbation of asthma and impairment of lung function.

The majority of environmental policies and regulations worldwide therefore are motivated by public health concerns, and most economic valuation exercises have found that health impact constitutes the largest portion of environmental damages. It has long been recognized that the environment in which people live-from household to the global level – significantly affect their health. Until recently, however, neither it was possible to quantify the magnitude of health impacts from exposure to various environmental factors, nor it was possible to compare the cost effectiveness of preventive measures to reduce such exposure with health sector activities to cure the resulting illness (Lvovsky, 2000).

2.0 eConoMiC tHeorY of MeaSurinG HeaLtH benefitSThe economic theory of measuring welfare changes is based on individuals’ Willingness To Pay (WTP) for a certain change in the provision of a good (e.g. air quality).

AbstractAir pollution is a serious problem because of the increased urbanization, and industrialization. It has long been recognized that the environment in which people live, from household to the global level, significantly affect their health. The effects of air pollution on health are very complex as there are many different pollutants and their individual effects vary from one to the other. The majority of environmental policies and regulations worldwide therefore are motivated by public health concerns, and most economic valuation exercises have found that health impact constitutes the largest portion of environmental damages. A review of various approaches of economic valuation of air pollution has been presented in this paper.

costs of air pollution reduction (the cost of reduction of one additional unit) (URBAIR, 1993).

3.0 MetHodoLoGY for eStiMatinG HeaLtH effeCtSHealth damage is generally expressed in terms of mortality and morbidity. It is well established that there is relationship between health damage and air pollution. The estimation of health and economic effects of air pollution involves the determination of following four factors; the dose response relationship, the susceptible populations, the relevant change in air pollution, and an economic valuation of the health end point. Epidemiological literature provides the dose response relationships between levels of air pollution and their adverse effects on human health, productivity, and in extreme cases human longevity (Ostro, 1994). The equations are expressed in the form: Change in condition = * (Change in air quality) (1) (Mortality / Morbidity) (SPM, SO×, NO×)

, is the partial derivative or slope of dose response curve

The dose response functions are of three types:

a. the first type relate to ambient levels of pollutant concentration to excess mortality;

b. the second type relate to ambient levels of pollutant concentration to specific symptoms, such as coronary heart diseases, bronchitis, asthma attacks, etc.;

c. the third type relate to ambient levels of pollutant concentration to non specific symptoms, such as Restricted Activities Days (RADs) and/or Work Loss Days (WLDs).

Health damage through air pollution can thus be expressed in excess mortality, increased incidence of specific diseases,

MEJ, Vol. 13, No. 10 May 201213

and in general health indicators such as RADs and/or WLDs (URBAIR, 1993). The next step involves multiplying β i.e. slope of dose-response curve by relevant population that is believed to be exposed and susceptible to the air pollution effect under consideration. The third step in the calculation of health effect of air pollution involves the estimation of change in air quality under consideration. The estimated heath impact can be represented as

dHi =β * POPi *dA (2)

Where dHi = Change in population risk of health effect I, POPi = Population at risk of health effect i dA – Change in air pollution under consideration

The last step involves calculation of the economic value of the estimated health impacts (Vi). The valuation could be developed from estimates of WTP for reducing risk, or a modified Cost of Illness (COI) approach, to value changes in morbidity. The three health impacts can be valued as

a. Excess mortality is valued with Value of a Statistical Life (VSL),

b. Specific diseases are valued on the basis of actual expenditure for prevention, detection and treatment of the diseases.

c. RADs and WLDs are valued on the basis of estimated loss of productivity, measured by average daily wages of the exposed population.

Thus, the change in total socio economic value of the health effects (dT) due to the change in air pollution under consideration in the summation of all the effects and can be represented as (Ostro, 1994):

dT = Vi * dHi (3)

3.1air Pollution dose-response StudiesAs outlined in the previous section dose-response functions correlate mortality and morbidity outcomes for susceptible population groups with ambient concentrations of a given pollutant. Mortality effects of exposure to particulates will be focused, as reduction in excess mortality valued with statistical value of life can be used for economic evaluation for intervention design. Chronic exposures to particulates can lead to premature death by exacerbating respiratory illness, pulmonary diseases, and cardiovascular diseases.

The reported epidemiological studies involve two principal study designs; time series and cross-sectional. The more common time series studies correlate daily variation in air pollution with variation in daily mortality in a given city and measure, primarily, the effects of acute exposure to air pollution. A cross sectional analysis compares the rate of prevalence of given health outcomes across several locations for a given period of time. The advantage of time series

studies are they do not have to control for a large number of confounding factors, since the population characteristics (age, smoking, occupational exposure, health habits and so on) are basically unchanged. On the basis of meta-analysis of acute mo4rtality studies that measures the ambient levels of particulates of less that 10 microns in aerodynamic diameter (PM10), estimates the average percentage change in total mortality per 10 µg ³ changes in PM10 ranges from 0.74 to 1.23 (World Bank, 1998).

Ostro (1994) reviewed some of the time series studies linking particulate matter mortality given in Table 1. The mean effect of a 10 µg/m³ change in PM10 implied by these studies varies between 0.31 to 1.49 percent, with a mean 0,96 percent.

Thus Central percent change in mortality = 0.096 *Change in PM10.

A recent study by Cropper et al. (1997) regarding the health effects of air pollution in Delhi, India compared the time series study in Delhi with other studies. They concluded that listed studies find a significant and positive relationship between (excluding Delhi) of six percent for a 100µg/m³ increase in TSP. by contrast, in Delhi a 100µg/m³ changes in TSP is associated with only a 2.3% change in total non-trauma mortality. The cause for low excess mortality can be, that a large proportion of particulate pollution in Delhi arises from natural sources rather than combustion of fossil fuels, and hence the chemical composition of the particulates in such that they pose a lower risk to health.

4.0 VaLuation of HeaLtH iMPaCtSThe methods used for valuation of health costs associated with environmental pollution can be grouped into two broad categories. The first includes methods that measure only the loss of direct income (lost wages and additional expenditures). The measures do not include inconvenience,

MEJ, Vol. 13, No. 10 May 201214

suffering, and other less tangible impacts to individual and family. Therefore they indicate only the lower bound of social costs and understate the total cost to individuals. The second category includes approaches that attempt to capture individual’s willingness to pay to avoid or reduce the risk of death or ill health. These techniques are summarized in Table 2.

4.1 Human Capital approachIn policy analysis involving decision, which affects changes in risk to life, it is often necessary to estimate the value of statistical life. Human capital approach considers individuals as units of human capital that produces goods and services for society. The value of life of an individual is computed as the summation of the foregone income stream discounted to its present value. Mathematically value of statistical life (VSL) (Ortolano, 1997) is

VSL =

t = j

Y Pjt

t

t - j

(1 + )

(4)

Where Yt = Present annual income Pj = Probability in year j of the person being alive Y = Discount rate

The values calculated are dependent on the age of death and on income, skill level and country of residence. The

factor such as possible increase in income in future and the reduced probability of being alive at each year is not accounted as these two factors act in opposite direction, the net effect on statistical value of life will be minimal.

4.2 Cost of illness (Coi) approachThis approach applies to the morbidity and is consistent with human capital approach. The direct cost of morbidity can be divided into two categories: medical expenditure for treating illness (a large portion of cost of hospital admissions and emergency room visits) and lost wages during days spent in bed, days missed from work, and other days when activities are significantly restricted due to illness.

The economic evaluation is estimated as per the following equation: E = b(dj) * COI(dj) * { RR(pi, dj) -1 } (5)

where, E = economic cost of morbidity by hospital

admission b(dj)= actual hospital admission and out-patient doctor

consultation due to a particular disease dj dj = diseases (e.g., respiratory or circulatory

diseases) COI= estimated cost of illness related to hospital

admissions and out-patient treatment due to dj RR = Relative risk for morbidity - pi, dj (air pollutant &

disease specific in respective order) pi = air pollutants (e.g. NO2, SO2, RPM etc.)

In practice, COI is first computed based on the statistics on hospital admission and the result obtained is subsequently applied in the model. In this way, the economic cost associated with hospital admission is the product of the total cost of illness and the relative risk (RR) of admission. RR is obtained by multiplying the exponential of the regression coefficient by the defined increase in the pollutant. For the calculation of COI for morbidity, where hospital admission is expected to be the key cost component, the direct and indirect cost related to the illness are identified as:------------------------------------------------------------------------------direct cost indirect cost------------------------------------------------------------------------------Self medication Output (earning) loss

Buying medication Off-work day (not seriousover the counter enough for admission)

Defensive expendituree.g., special diet, equipment

Hospital Admission:Average length of hospital stay Room rate per day Subsidies involved------------------------------------------------------------------------------

MEJ, Vol. 13, No. 10 May 201215

4.3 Preventive expenditure approachDefensive expenditures are the expenditures made by individuals to prevent or counteract the adverse effects of pollution. One of the means of avoiding the adverse effects of pollution is to move to a cleaner environment for extra expenditure.

4.4 Willingness to Pay approachThe mortality approach in the valuation literature has been mainly based on the estimation of the willingness to pay for (or willingness to accept as compensation for) a change in the risk of death. This is converted into the ‘value of a statistical life’ (VSL) by dividing ghe WTP with the change in risk. For example, if the estimated WTP is $ 100 for a reduction in the risk of death of 1/10000, the value of a statistical life is estimated at 100*10000, which equals one million dollars.

Mortality impacts are valued bu multiplying the change in risk of death by a “value of statistical life” (VSL). The values of VSL can be transferred to other countries through the use of an ‘income elasticity’. In order to facilitate the comparison of economic activity between countries, the UN’s International Comparison Programme (ICP) developed internationally comparable measures of GNP, known as purchasing power parity (PPP) estimates of GNP; these are derived using purchasing power parities as opposed to exchange rates as conversion factors. The PPP conversion factor is defined as the number of units of a country’s currency required to buy the same amounts of goods in the domestic market as one dollar would buy in the United States (World Bank,1996). In order to assist researchers in estimating the health benefits of employment World Bank, 1996 provides the VSL for different countries based on an income elasticity of 1 and the VSL for an elasticity of 0.35. Both sets of figures use a VSL for the US of $4.0mn. the PPP GDP per capita for the US is $25,880 based on data from the World Bank Development Report. On this basis PPP GNP of India is $1280 and VSL for India is $1397000 (World Bank, 1996).

WTP estimates go beyond the lost of earnings and medical costs. However, WTP values are mainly obtained from contingent valuation and they are grouped as follows:l WTP to avoid the symptoms of the diseases

concerned:l Light symptoms without the need for doctor

consultationl One symptom day suffered (descriptions of symptoms

provided)l Seven symptom day sufferedl WTP to avoid hospitalization specific to the diseases:l One day of hospitalization l One week of hospitalization

In substituting the WTP values to estimate the economic cost of morbidity, we use a similar equation to the one used for COI estimates for hospital admissions. COI input is substituted with WTP. The equation is given as :

E = [ b(dj) * ( RR(pi, dj) -1) ] * WTP(dj) (6)

where, E = economic cost of morbidity (by hospital admission

& out-patient attendances) b = actual hospital admission and out-patient doctor

consultation of a particular illness dj dj = illness (e.g., respiratory, circulatory diseases) RR = Relative risk for morbidity due to (pi, dj) (available

from study by HKU) pi = air pollutants (e.g. NO2, SO2, SPM etc.) WTP = estimated monetary value WTP to avoid dj

The average WTP value to avoid a day of hospital admission is taken into account. In addition, the average willingness to pay by individuals' to avoid the symptoms during the disease occurrence (non hospitalized cases) is also considered in the calculation.

4.5 Wage differential approachThe basic idea behind compensating wage differential is that jobs can be characterized by various attributes, including the risk of accidental death. The workers are described by the amount they require as compensation for different risk levels, while the firms are characterized by amount they are willing to offer workers to accept different risk levels. The matching of wage offers and acceptance determines the hedonic wage equation, which describes the compensation received for bearing risk at market equilibrium (Simon et al., 1999). The value estimated from observed labour market data and converted to values of statistical life(VSL) are used to value reduction in risk of death achieved by environmental health programmes. Valuing mortality risks using earnings-they so called human capital approach – likely to under state what people themselves would pay for small risk changes. Value of statistical life in India, using estimates of compensating wage differentials obtained from Occupation Wage Survey (OWS) data obtained from Indian Labour Bureau for Indian manufacturing industry was found to be in the range Rs.64,17,341 to Rs.1,50,40,642 i.e, US $1,53,000 - US $3,58,000. Ratio of VSL to forgone earning is in ratio 20-48 (Simon et al., 1999). In another study, VSL for India considering technicians in cotton textiles and man made textiles was determined to be 8.4 million rupees (Gaggar, 1995).

monetary value of improved health for children and adults. For any intervention with cost C, the benefit cost logic suggests that households have an incentive to adopt the intervention as long as benefits are more than the costs.

introductionSun is the sole important source of energy on earth. Without sun, life on earth would not be possible. The estimation of solar radiation incident on a particular horizontal surface is important in determining the performance of solar collector, passive cooling systems, freezing problems in liquid flat plate collectors etc. Global solar radiation is even helpful in determining the energy state of active surfaces and lower atmosphere. The global solar radiation is maximum in the morning and decreases by evening. Daily solar radiation is minimal in December and maximal in July. Solar radiation is estimated on a very small area and hence, it is impossible to estimate the solar radiation on a large area. Therefore, global solar estimations are arrived at using theoretical models [3].

The first attempt to estimate the global insolation incident on a horizontal surface is the Angstrom formula:

HH

nN= a + b

(1)

Where H and H 0 are monthly mean daily solar radiation on a horizontal surface and on the top of the atmosphere respectively.

The monthly average values of daily solar insolation are important for developing an insolation model. On clear sky days, the solar insolation is due to the direct beam radiation whereas on cloudy skies the solar insolation is due to the diffused radiation. The proposed models for estimation of the global solar radiation depend upon certain parameters like:1. Precipitable water2. Pressure3. Angstroms spectral turbidity coefficient4. Angstroms wavelength

AbstractThe main objective of the current study is to develop a prediction model which can be used to estimate the global insolation on a horizontal surface at Vellore region using clearness index (KT). The latitude of the desired location, time and the amount of total precipitable water content are the two most important parameters taken into account. The developed results could be applied to design and sizing of a solar thermal or solar photovoltaic system. In this work, the predicted global radiation, kWh/m2 is plotted with the time (January to December) at the selected location i.e. VIT University, Vellore.

All these parameters do not participate equally in the clearness index. Clearness index is a very important concept in solar energy estimation and it varies with time, season , climatic condition and geographic location[2]. Therefore to develop a model for the clearness index is very essential. Some of the models to determine the solar insolation are described below:

1. Hoyt’s model: This model is dependent on scattering ratios of air and dust, and absorption ratios of water vapour, carbon-dioxide, ozone, oxygen and dust. These parameters cannot be measured directly and depend on other parameters. Hence, this method of acquiring parameters is very expensive.

2. Excell’s model: Fourier series is used to calculate daily global solar radiation. This method for the estimation of the clearness index is very complex.

3. Atwar balls model: This model is based on two parameters i.e absorption and transmission the radiation. Which cannot be measured and hence, are dependent on other parameters. Therefore this is expensive and difficult.

In the present study. model is being developed based on two factors

1. Latitude of Vellore

2. Precipitable water at the location

Latitude of Vellore is determined using a GPS (Global positioning system) receiver. Precipitable water at a location is determined using daily humidity data received. Hence, the model developed is quick and cost effective.

The estimation of solar radiation is used for sizing any solar energy system which requires the knowledge of the availability of solar radiation data at the interested location.

MEJ, Vol. 13, No. 10 May 201218

The average distribution of solar radiation over the day is of fundamental importance in many areas of solar energy [4]. It provides the basis for predicting the instantaneous solar radiation from the commonly available monthly averages of daily insolation.

ModellingThe monthly average of daily global solar radiation data are collected over different locations in Vellore .These data are reduced to monthly average clearness index by taking the ratio of measured global radiation to the calculated extra terrestrial horizontal insolation. This is calculated from the following expression.

H0=(24I0/π){cos().cos().sinsr+ sr sin()sin()} kWh/m2 (2)H0 = extra terrestrial horizontal insolation in kWh/m2I0= extra terrestrial irradiance in kW/m2

The horizontal insolation depends on the day of the year and latitude of the place. Therefore it can be calculated for any day of the year which does not include any atmospheric effects.I0 = Isc{1+0.033cos(360N/365)} (3)

Where, Isc = solar constant=1.367kW/m2 N = day of the year = latitude of the location = declination angle =23.45sin{2π(N-80)/365} (4)

sr =cos-1(-tan .tan ) (5)

From the above expression we conclude that the extraterrestrial horizontal insolation depends on latitude and day of the year. However the calculated insolation does not take any atmospheric effects into account [5].

The clearness index KT, gives the measure of the atmospheric effects at a place on the insolation . However the clearness index depends on time of year, season climatic condition and geographic location. A plot of KT versus day of the year shows that the variation of KT over a period of one year is a periodic function.KT is represented by the following fourier series:KT =f(x,w,t)+e (6)where, f(x,w,t)= A1+A2sint+A3sin2t+A4sin4t+A5cost +A6cos2t+A7cos3t (7)where,x=latitude of given locationt=arguments of trigonometric termsN=day of the yearA1,A2,....A7= functions of latitude

w=total precipitable water vapour in the atmosphereAi= ai1 + ai2x + ai3x2 + ai4w + ai5w2 (8)

f(x,w,t) = (a11 + a12x + a13x2 + a14w + a15w2) + (a21 + a22x + a23x2 + a24w + a25w2 )sin t + (a31 + a32x + a33x2 + a34w + a35w2)sin2t + (a41 +a42x + a43x2 + a44w + a45w2) sin3t + (a51 + a52x + a53x2 + a54w + a55w2)cost + (a61 + a62x + a63x2 + a64w + a65w2)cos2t + (a71 + a72x + a73x2 + a74w + a75w2)cos3t (9)

results and discussion

fig 1: Variation of clearness index withdifferent months of a year

Figure 1 shows the variation of clearness index with the change in months. It shows that the clearness index is increasing from the month of January to June and then falls from June onwards till December. This shows that during summer, the atmosphere is more clear and the incoming global solar radiation is more as compared to the winter season where the atmosphere is not so clear and the incoming global solar radiation is less. This global solar

MEJ, Vol. 13, No. 10 May 201219

radiation is directly proportional to clearness index which gradually changes over different months of a year.

fig 2: Global insolation result over Vellore region

Figure 2 shows the variations of global radiation that change with the months of a year. From the figure it is clear that the global radiation increases delivering the period January to August and then decreases by December. The peak global insolation observed as 6.25 kWh/m2.

ConclusionA prediction model has been developed to estimate the solar radiation at Vellore using Fourier coefficients. This model has been applied to some of the cities in the Indian sub-continent and validated. It is developed for Vellore and the results are estimated.

Central Institute of Mining & Fuel Research, Nagpur carried out the study of “Rippability Assessment of Rock Mass at an Iron Ore Mine in Karnataka” by using seismic profiling techniques. The study was conducted with a view to avoid the Environmental effects to the surrounding Sensitive Structures as a result of drilling and blasting. The refraction seismic survey was conducted on all the 4 benches of the mine to determine the compressional (P-wave) wave velocity, which has got the established correlation with rippability. The Refraction seismic survey was conducted to aid in the evaluation of the rippability of the subsurface material (Iron Ore) of the mine. The state of the art instrumentd Geode (Make:Geometrics controllers Inc., USA) was used for acquiring the seismic data and the method of profiling carried out was refraction seismic survey. The in-situ P-wave velocity obtained from all the test sites was in the range of 2000-3000 m/s, which was rippable as per the guidelines provided by the standard Ripper-Dozer manufacturers.

1. introduCtionA refraction seismic survey was conducted on all the benches of the mine to measure compressional-wave seismic velocities (P-wave) to aid in the evaluation of the rippability of the subsurface i.e. Iron ore of the mine. The state of the art instrument called Geode (Make:Geometrics controllers Inc., USA) was used for acquiring the seismic data and the method of profiling carried out was refraction seismic survey.

Surface-wave tohography is an efficient way to obtain images of the group velocity at a test area of rock formation, because Rayleigh-wave group velocity depends on frequency. There are separate images for each frequency and at each point in these images the group velocities define a dispersion curve, a curve that relates group velocity to frequency. Extending the common use of surface wave analysis techniques from estimating shear wave velocities and compressional wave velocities for detection and/or imaging required a multichannel approach to data acquisition and processing. Integrating the multichannel analysis of surface waves (MASW) method with a common mid-point (CMP)-style data acquisition permits the generation of a laterally continuous two dimensional (2-D) shear wave velocity field cross-section (Park et al., 1999; Xia et al., 1999). The MASW method as used here requires minimal processing and is relatively insensitive to cultural interference. Mating MASW with the redundant sampling approach used in CMP data acquisition

provides a non-invasive method of delineating horizontal and vertical variations in near-surface material properties.

Continuous acquisition of multi channel surface wave data along linear transects has recently shown great promise in detecting shallow voids and tunnels, mapping the bedrock surface, locating remnants of underground mines and delineating fracture systems (Park et al., 1999). Extending this technology from sporadic sampling to continuous imaging requiredsthe incorporation of MASW with concepts from the CDP method (Mayne, 1962). Integrating these two methodologies resulted in the generation of a laterally continuous 2-D cross-section of the shear wave velocity field. Cross-sections generated in this fashion contain specific information about the horizontal and vertical continuity and physical properties of materials at shallow depths (few inches to over 300 ft.) Seismic reflection surveys are generally designed to image structural and stratigraphic features with a high degree of resolution and accuracy. On such surveys, surface waves are considered noise. For our application, however, it is possible to exploit the sensitivity of the surface wave to changes in material velocities that make up half-space it travels through. Surface wave propagation depends on frequency (depth of penetration), phase velocity (compressional and shear), and density. All of these properties will affect the surface wave dispersion curve (phase velocity vs. frequency) in a predictable fashion. Since shear wave velocity has the greatest impact on the properties of a surface wave, we can invert the dispersion curve in such a way as to obtain the shear wave velocity as a function of depth (Xia et al., 1999). Borton (2007) says that the phenomena of seismic anisotrophy giving lower stiffness perpendicular to layering than in parallel, has been used since nineteenth century for investigating fractured rock at depth. The same analogy holds good for compressional wave velocity also. The objective of this experimental work has been to find out the compressional-wave (Vp) structure and from these dispersion curves to get the inferences regarding the structural quality of the strata. Ramulu et al (2011) extensively used the seismic refraction technique for determination of Vp of rock mass for blast optimization by impedance matching of explosives. This paper deals with the application of seismic profiling for rock mass characterization for rippability analysis of various benches of the mine.

Belt referable as the “Dharwars” a group of Precambrian schistose rocks of Mysore. The lithological units include green stones which are the metamorphosed basic igneous rocks occupying the valley regions, with phyllite – quartzite’s forming the canoe – shaped amphitheatre of hills trending NNW – SSE and enclosing Sandur. The phyllite is locally shaly and the quartzite’s are of the nature of banded hematite jaspers and banded hematite quartzite’s, inter banded with each other. The Bellary – Hospet area is bounded by 15° 13’ 45” latitudes and 76° 25’ 30” longitude and is covered in Survey of India of Toposheet No. 57 A/8.

LOCAL GEOLOGY:The general sequence of rock formation in the area is Soil, Iron ore floats, Iron ore reef, Banded hematite quartzite and Shale/Phyllites. The strike of the iron ore deposit is 900 m in north west & south east direction and average width of the deposit is 45 m in north east & south west direction and the quality of iron is analyzing 64% Fe to 66% Fe. The recovery of the ore is 85% and balance 15% is consisting of sub grade.

As observed in the workings, the type of ore is powdery and in some places hard, colour of the deposit is blue & red and ratio of fines & Lumpy ore will be 60 : 40. In northern portion of the lease area, float ore can be seen and this float one area covers about 20 Ha and thick ness of the float ore is ranging from 0.50 m to 2 m and average thickness is only 1m. The size of the float ore body is 10mm to 300 mm and quality is 62% Fe to 65% Fe and samples from mine faces were collected and prepared by quarter & coning method. The Fe content in the drill holes is 64% to 66%. No other structural disturbances like folds & faults are observed in the leased area.

3. fieLd inVeStiGationSRefraction seismic data were acquired at three different locations, covering all types of rock formations. Stakes were placed at the end of each seismic line and stations along

the lines were marked with flagging/coloring. The tests were conducted at ER Section (ROM) of RL-738, MR section of RL-748 and ER section (Development) of RL-744 in Phase-I experiments and at ER Section (ROM) of RL-738, MR section of RL-735 and MR section (Development) of RL-748 in Phase-II experiments, which are the hardest exposed formations in the mine.

The 24-channel refraction seismic data were acquired with medium frequency geophones, and a 10-pound sledge hammer source. The geophones were located 3m apart and source impacts were made at various distance offsets and along the seismic profile. The geophones were located on a straight line and distances were measured with tape. Relative elevations were surveyed and determined with the help of GPS based device. The seismic data were stacked, normally,15-20 times at each source point to increase the signal-to-noise ratio. Stacking with hammer, or signal enhancement, involved repeated source impacts at the same point into the same set of geophones. The quality of the recorded seismic data was excellent and easily identifiable on first arrival of seismic energy. The experimental set up is shown in Figures 1-2.

4. data anaLYSiS and reSuLtSThe refraction seismic data were processed and interpreted by using the PICWIN seismic wave analysis software provided with the system. The general processing and interpretation flow consisted of the initial selection of the seismic first breaks, creation of data files for input into the interpretation program, and interpretation of the data using modeling and iterative ray-tracing techniques. The output of the data analysis for all the three test sites is given in Figures 3-5.

The in-situ compressional wave velocities of iron ore lumps collected from different test sites by refraction seismic survey are given in the Table-1. The laboratory tests were also

7. ConCLuSionSThe following conclusions can be made from the above study:

1. The P-wave velocity for the waste rock is less than the Ore by about 35%

2. The P-wave velocity profiles clearly indicate that all the benches of the Iron Ore Mine are RIPPABLE by the Komatsu Ripper-dozer, Model D475 Giant Ripper as the maximum P-wave velocity observed was below 3000m/s from the hardest section of the mine.

3. The Rippability analysis was conducted up to 35m depth only and similar study should be conducted at depths beyond 35m.

For implementing Safety Management System all performed activities are to be identified. An activity flow chart that starts from, marking of overall and annual stripping limit and ends at the last activity of dispatch, should be made. In its path it should also cover activities that are outsourced inside the mine (egs. OEM jobs on contract or outsourced and performed outside the mine that will have bearing for safety inside the mine like fabrication of parts in outside facility). Procedure for procurement should also be included as an activity as, the performance of equipment will have direct bearing on safety.

Once activities are identified they should be classified location-wise or equipment-wise or activity-wise. Purpose of this is to ensure that all jobs are covered under hazard identification and later control measures application. These should be dissected to as small components as possible. Success of implementation will depend upon the fineness of dissection. (Annexure 1).

Each such component should be gone into in detail for the risk assessment by assigning proper numerical value for

probability, exposure and consequence, as given in DGMS circular 13 of 2002 (See table below). Assigning values should have consensus of the team and should not be unilateral. Similarly control measures should be practicable, adoptable, convenient, cost effective and understandable by those who execute it. Control measures should not be used to settle intradepartmental or personal scores. Should it be necessary, training by OEM or training centers should be included. A control measure that is not properly executed can by itself become a hazard and may have higher risk rate than without it.

Hazards: Source of potential harm, injury or loss

risk: Combination of the likelihood of a specific unwanted event and the potential consequences if it occurs.

risk assessment: It is a process that involves measurement of risk to determine priorities and to enable identification of appropriate level of risk treatment

risk rating: It is the category or level or risk assigned following risk assessment (eg. High, Medium, Low)

MEJ, Vol. 13, No. 10 May 201231

risk Control: It is implementation of strategies to prevent or control hazards

HierarCHY of ControL(riSK ControL MeaSureS)

elimination: Removal to eliminate the hazard completely (100%)

Substitution: Replacement with less hazardous material, substance or process (75%)

Separation: Isolating the hazard from person by guarding, space or time separation (50%)

administration: Adjusting the time or conditions of risk exposures (30%)

training: Improving skills making tasks less hazardous to persons involved (20%)

Personal protective equipment: Used as the last resort to appropriately designed and properly fitted equipment where other controls are not practicable (5%)

baSe & reSiduaL riSKBase Risk Assessment ignores existing controls and therefore, evaluates the inherent risk associated with an activity or situation.

Base risk assessment is used to identify whether an activity or situation has sufficient level of associated risk to merit its management through safety management system (i.e. responsibilities allocated, performance monitored & audited, performance recorded, training given etc.)

residual risk assessmentResidual risk assessment takes into account the level of risk while the activity is under the control of the organization.

Residual risk is therefore, used to measure how well an activity or situation is managed. Where the level of residual risk is unacceptably high, controls need to be modified or the risk eliminated. This type of risk assessment is often used to identify objectives for improvement of system.

Hazards and their base risk ratings are arranged in descending order. For each risk all possible control measures are to be identified and after applying control measures, residual risk is to be worked out. Residual risk may or may not be in descending order. Where activities have overlapping tendency (Egs. loading by excavator takes both excavator as well as dumper operation) impact of one control measure on the other needs to be assessed. The most practical measures that would bring residual risk within tolerable zones will determine the acceptability or otherwise

of the control measure; ideal being bringing the risk rating to trivial level.

Values for consequence, probability and exposure are site specific Egs Hauling load down gradient could be in a

• Hillyterrainorfromtopbenchtolowerlevelssaybackfilling

• The area having high rainfall and monsoon or lowrainfall area and monsoon,

• Foggyatmosphere,

• Slipperyhaulroadduetopoorloadbearingcapacityoffloor below or due to rains or due to tread pattern and mud clogging.

• Type of material handled (large boulders/aggregateof fines and medium sized stones/ silt accumulated at pit)

• Technicalcaliberofmanpowerforoperation(selectionof gear ratio)

• Technicalbackupandrepairfacility,repairbyOEMonoutsourcing and if so, overriding clauses or passing buck situations

• Conditionofequipmentold/new/stateoftheart

Thus, activity remaining constant, values would vary. Values so assigned should be accepted by all in the team.

If residual risk falls in moderate or substantial category, efforts should be made to further reduce the risk and risk reduction control measures implemented. The aim of control measures would be ALARA (As Low As Reasonably Acceptable)

If activity is unavoidable, an emergency procedure to meet eventualities called Emergency Management Plan (EMP) is to be made. This should clearly specify the unsafe conditions that would exist, precautions to be adhered and reasons for failure of control measures and indicators that would warn for abandoning such activity (triggers).

egsHandling of silt from pit bottom that could slide and engulf loading machine. Pre closure activities and reduction in bench width that could effect on slope stability, unloading of waste in water logged area

The values that are assigned cannot be universal therefore, categorizing as trivial, tolerable, moderate etc also will depend upon site variables. Categorisation will depend upon rating and rating will intern depends upon site based perception by the team

Exercises like monitoring and fine tuning would follow. These exercises are not one time affair but are continuous and get honed over a period of time

risk based control plan

risk level action and time scale

triViaL No action is required and no documentary record needs to be kept.

toLerabLe No additional controls are required. Consideration may be given to a more cost effective solution or improvement that impulses no additional cost burden. Monitoring is required to ensure that the controls are maintained.

Moderate Efforts should be made to reduce the risk. But the cost on prevention should be carefully measured and limited. Risk reduction measures should be implemented.

SubStantiaL Work should not be started until the risk has been reduced. Considerable resources may have to be allocated to reduce the risk. Where the risk involves work in progress, urgent action should be taken.

intoLerabLe Work should not be started or continued until the risk has been reduced. If it is not possible to reduce the risk the activity should be suspended

A small workout for a few activities connected with wheel loader is made and is indicated at Annexures 2 & 3.

In case of risk of wheel loader while loading is to be worked out, a combined risk rate would come in and the higher value risk will have to be taken into consideration first and lower one later.

While wheel loader is engaged as LHD for feeding crusher, impact on crusher also would need to be taken into consideration.

Similarly if size of fragment and effect on loading as well as hauling unit is to be considered ,fly rock risk due over charge and excess throw is also to be worked out,

Thus risk rating should not be done in isolation.

Conclusion. Identifying hazard, assessing risk and applying control measures go a long way in the making the mine personal aware of the hazards and risk involved therein. Ignorance of these is a major contributor to accidents. A goal setting or self regulatory process always has better participation as compared to prescriptive legislation.
