1.1.3 Brief Description of the Nature of the Project

The proposed project is for expansion of quantity of Varada Bauxite Mine from 27189TPA to 324430 TPA ROM.

The mine lease is a piece of non-irrigated barren land. Total reserves of 1614265 MT.

In Varada Bauxite Mine the nature of deposit is bedded, mineral bauxite is present in form of bed, which is

overlain by a thin cover of Soil, The proposed project entails open cast semi mechanized mining in the mining

lease of Varada-I & Varada-II. As the mining lease was already worked out therefore on the basis of geological

data gathered from the working pits, trial pits, ore reserve were estimated.

Category wise reserves of Bauxite are summarized in Table 1.1

1.1.4 Demand-Supply Gap

This is an existing captive mine for supply of high grade material to Orient Abrasive Limited’s Plant located

at Porbandar. The plant is under expansion, the Supply and Demand gap is 40%, and the project clearance

will further reduce the Demand & Supply gap. Hence demand supply issues whilst important, are

considered in the current situation.

1.1.5 Imports v/s Indigenous Production

This is an existing mine for the supply of high grade material to OAL’s plant located at Porbandar and OAL has

not imported high grade material yet.

Indirect

Few people would be engaged in providing support services to the mining operation including transportation of

ROM, supply of Drinking water, water tanker for Dust suppression etc.. The exact number of such persons

is likely to be in the order of ~ 20-30 for each lease area.

Bauxite produced from mine will be processed in OAL plant at Porbandar and final product will be sold to

customers for use or further processing. This will generate additional economic demand that could translate into

additional employment.

Life of Mine

Mining will be carried out at a maximum production of 324430 TPA and as per IBM approved Scheme of Mining

the life of mine would be 6 years. Entire lease area leaving statutory barrier will be mined out in 6 years.


As per estimated Mineable reserves of 474429 MT of Bauxite available with average annual production proposed

of Bauxite is 120000 MT, the balance Mine Life period is 5 years.


As per estimated Mineable reserves of 772383 MT of Bauxite available with average annual production proposed

of Bauxite is 130000 MT, the balance Mine Life is 6 years.

1.2.6 Conceptual Mining Plan

Ultimate Pit Limit

In the Mining lease area the mineralized limits are determined either by the limit of the mining lease boundary

or by the limits of the ore body. These limits have been duly marked in the geological plan. The life of mine is 6

years. During mine life period entire lease area leaving statutory barrier will be converted into one common pit

and pat of this pit will be backfilled and remaining part will be converted into reservoir. The conceptual plan has

been prepared up to the life of the mine is 6 years only. The lease area of Varada-I will be converted into one

pit having dimension 710 m in length. Width varies from 40m to 290m and average depth will be about 4.4m.

The lease area of Varada-II will be converted into one pit having dimension 1060m in length. Width varies from

20m to 190m and average depth will be about 5.5m.

Stacking of mineral reject and disposal of waste:-


The backfilling will be done in the area after winning full thickness of bauxite. The OB and waste generated

during scheme period will be back filled in the mined out area in west part of the lease area. The waste generated

during three years mining scheme period will be backfilled in mined out area at the time of generation if self

hence question of its height and spread does not arise. As volume of voids (area to be worked) is much more

than material available for backfilling of backfilling of entire mined out land upto original ground level will not

possible. Therefore waste part of the area will be backfilled and another part of the lease area will be used as

water reservoir.

Raw Materials

Proposed project is mining of ROM for recovery of high grade bauxite for captive use in OAL’s plant located at

Porbandar.


MINING OF 324430







Marketing

Company has got lease for its captive consumption. So high grade material is completely used for companies

own plant situated at Porbandar. The low grade which lessee get with abrasive and refractory grade is dumped

separately & lessee sale it when get permission from state govt.

Volume Closing stock of material

Mode of Transport

Bauxite will be transported by tractor to stacking and sorting ground. High grade bauxite will be transported by

hired /owned truck to company’s manufacturing unit at Porbandar. Low grade bauxite will be stacked separately.

1.2.11 Resource Optimization / Recycling and Reuse Envisaged in the Project

The following will be done

The mineralized waste generated during the mining period will be backfilled in order to reduce the change

in land cover or topography of the area. This backfilled area will be used for greenbelt development

Complete backfilling is not possible so a part of mine out area will be used as water reservoir and

stored water will be used for watering the plantation and for dust suppression. In addition to this water

stored in mined out pits will be used by farmers and villagers in nearby area thus reducing the ground

water dependency.


MINING OF 324430







Mine will be worked only in day time (8 hr/ day) and around 98 persons will work, therefore the

domestic waste generated will be low and it is possible to recycle. As it doesn’t require electricity

because working will be only in Day time.

1.2.12 Availability of Water its Source and Energy/Power Requirement

Water

For domestic use water will be supplied by the means of tankers from the nearby village.

For greenbelt development and dust suppression water stored in mined out pits will be used.

For domestic purpose: 3.815 KLD

For dust suppression: 44 KLD

For plantation: 1.05 KLD

Fuel/Power Requirement

The mine will be worked during an eight hours shift i.e. during day time only and hence no electricity is required

for lighting. Diesel, ~3 lit/hr will be used as fuel for running pump for dewatering in rainy season that too for

some time.

2.2.13 Waste Generation and Management

Nature of Waste & Rate of yearly generation

In the proposed mining scheme the OB is likely to be generated during scheme period will be Soil and will be

spread on backfilled area.

The waste that is likely to be generated will be in the form of associated clay with the bauxite horizon as mineral

waste which is below the threshold grade, which has no sale value. That will be backfilled in mined out pits.

Quantity of Waste

The waste generated during scheme period will be as under:-


Year Soil Volume in M3 Volume of Waste (in M3)

Selection of Dumping Site

In the proposed mining scheme, it is proposed that waste generated during scheme period will be backfilled in

the mined out area west part of Varada-I mining lease area & east part of Varada-II mining lease area

simultaneously and soil will be spread on backfilled area. Part of mined out land will be used as water reservoir. Method of Dumping & Maximum Height and Spread of dumps



during scheme period will be back filled in the mined out area in west part of the lease area. The waste generated

during three years mining scheme period will be backfilled in mined out area at the time of generation if self

hence question of its height and spread does not arise. As volume of voids (area to be worked) is much more

than material available for backfilling of backfilling of entire mined out land upto original ground level will not

possible. Therefore waste part of the area will be backfilled and another part of the lease area will be used as

water reservoir.

2.8 Analysis of proposal (Final Recommendations)

2.8.1 Financial and Social Benefits with Special Emphasis on the Benefit to the Local People

including Tribal Population, if any, in the Area

Critical analysis of the existing socio-economic profile of the area vis-à-vis its scenario with proposed

project activities identifies the following:

About 98 miners will be engaged in mining activities for the project and about 60 people for ancillary

activities.

The proposed activities shall generate indirect employment in the region due to the requirement of

workers in supply auxiliary such as higher machinery service and Ore Transport service afford from the

ancillary works, which would marginally improve the economic status of the people.

Further the additional benefits from the downstream units such as iron industry, steel industry, cement

plant, and metallurgical industry also add value to the society.
