3.5. PROJECT DESCRIPTION

The economical depth of mining is taken as 35m having considered existing bore holes and

outcrops such as limit of lease boundary. Topsoil shall be removed; one benches of

weathered rock and four benches are designed to exploit the granite blocks by conventional

methods. The benches each of 5m height and width not less than the height are designed to

win the blocks.

Top soil shall be removed and stacked separately along lease boundary as earth bund which

will be used for afforestation purposes in phases. A bench height of 5m and a width not less

than the height and three working benches, each with a height of 5m as equal to the height of

the excavator boom and the width more than 5m is proposed to be maintained for safe

movement of machinery. The bench slope is maintained not more than 60° from horizontal.

S1 fencing shall be constructed at the top of high benches in order to safe guard the

9

unauthorized entry of men and machinery. In the case of entry, G1 fencing as a parapet

should be made to control trespassers.

3.5.1. Drilling and Blasting

Drilling of shot-holes will be carried out using compressor and Jack hammer combination.

Depth of holes shall be 1-2m. The spacing shall be 0.75m and burden shall be 0.60m from the

preface depends upon the size of block. To achieve a correct blasting geometry, certain

amount of trial blast is pre-requisite to effect a perfect pre-determined fragmentation and fly

rock control. In case of heavy blasting, a qualified Mines manager has to be appointed for

proper calculation of powder factor, control blasting, sequencing and arrangements of

explosives.

The massive formation shall be broken into pieces of portable size by jack hammer drilling

and shot hole blasting. Powder factor of explosives for breaking such hard rock shall be in the

order of 6-7 tonnes per Kg of explosives.

A controlled Blasting technique is adopted to open a pre-determined crack of the block from

the parent body. Shot-hole with 32-40mm dia. which are drilled by line drilling and Jack

hammers at a close spaced interval of 30cms will be initiated suitably with any one or more

of the following methods,

a) Pre-splitting

b) Cushing blasting with low strength and very low dia. Cartridges axial priming or

standard dia. cartridge with intermittent stemming materials.

c) Water impulsion with Detonating cords of sufficient power, preferably 10gms per

meter to develop cracks along the line of drilling.

3.6. RESOURCES

Total Geological resources (A) = 172823MT

Mineral reserves blocked under Mine benches (B) = 16247 MT

Mineral reserves blocked in safety zone (C) = 13226 MT

Then,

Total Mineable/Recoverable reserves = A-(B+C)

=172832-(16247+13226)

=172832-29473

Mineable reserves calculated as =143350 MT

4.3. TOPOGRAPHY

The area (Figure 4.3.) applied for Environmental Clearance. The area is almost hilly terrain

and its elevation ranges from 90-65m above mean level. Some part of lease area is disturbed

by quarrying .The other part of the area covered by the native plants and trees. There is no

water source found around the lease boundary. The Pathanamthitta district received the rain

under the influence of both southwest and northwest monsoons. The southwest monsoon

chiefly contributes to the rainfall in the district. Most of the precipitation occurs in the form

of cyclonic storms caused due to the depressions in Arabian Sea. The normal annual rainfall

over the district varies from about 2850mm.It is the minimum around Pathanamthitta in the

southeastern part of the district. The highest humidity is generally recorded in May with the

value of 87%. Throughout the month of August daytime temperatures will generally reach

highs of around 28°C that's about 83°F. At night the average minimum temperature drops

down to around 22°C, that's 72°F.

Chapter 5: Planning Brief

5.1. PLANNING CONCEPT

Excavation of building stone granite is planned and described in section 3.4 and 3.6.

Proposed land is a Patta land which does not come under Residential, Forest or any other

sensitive land classification. As a small project, it is not demanding any town or country

planning. However, approach roads and haul roads will be laid for the transportation of

excavated materials to the market and to the dump.

5.2. POPULATION PROJECTION

The proposed project will not affect the village population, and hence population projection is

not significant. However, it provides occupation to about 36 persons of which 80% of them

will be from the local villages. Other than mine employment, workshops, spare parts, tyres

and tubes and related several self-employment opportunities.

5.3. LAND USE PLANNING

The present and proposed land use pattern is given in clause 23 of Table 1.1.

5.4. INFRASTRUCTURE DEMAND

Labour shed, Surface latrines and urinals are required to be constructed for making easy

accessibility from the working area. No other infrastructures required.

5.5. AMENITIES/ FACILITIES

List of equipments and materials required for drilling, loading, transporting is given in table

5.6. HAZARDS AND RISK MANAGEMENT

5.6.1. Explosives

Blasting is done by means of explosives which are hazardous during of handling, storage and

blasting.

5.6.1.1. Storage and Handling

The Applicant is advised to store the explosives as per the Indian Explosives Act, 1958 and

the Explosive Rules, 1983. Necessary permissions should be obtained from the Joint

Controller of Explosives to store and uses of explosives in the quarry in the magazine permit

under Form - 23 or Agreement shall be made with holder of Form - 22 who can supply and

fire explosives as per safety practices. However blasting in the mine or quarry shall be done

as per the MMR, 1961 under the supervision of Mines Blaster certificate holder, appointed

under Reg. 160 of Metalliferous Mines Regulations, 1961.

5.6.1.2. Blasting

Poorly designed shots can result in misfires early ignition and flying rock. Safety can be

ensured by planning for round of shots to ensure face properly surveyed, holes correctly

drilled, direction logged, the weight of explosion for good fragmentation. Blast design,

charge and fire around of explosives should be carried out by a trained person.

5.6.2. Drilling

Slipping and Falling of labours from the edge of a bench during drilling is possible. Part of

training should include instructions to face towards the open edge of the bench so any

inadvertent backward step is away from the edge. Suitable portable rail fencing which can be

erected between the drilling operations and the edge of the mine can be provided.

Attachment of a safety line to the drilling rig and provide harness for the driller to wear can

be done. Newer drill machines are provided with cabin which controls noise level within

cabins. Driller operators should be protected with ear protection.

5.6.3. Loading

Possible risks during loading of mined rocks are falling of rock on the driver, plant toppling

aver due to uneven ground, failure of hydraulic system, fires, fall while gaining access to

operating cabin, electrocution in Draglines, failure of wire ropes in Dragline. In order to

overcome these risks:

Operator cabin should be of suitable strength to protect the driver in event of rock fall.

Electrical supply to dragline should be properly installed with adequate earth

continuity and earth leakage protection.

Wire rope should be suitable for work undertaken and be examined periodically.

Ensure that loaders are positioned sufficiently away from face edges

5.6.4. Transportation

Brake failure, lack of all-around visibility from driver position, vehicle movements

particularly while reversing, rollover, Vibrations, Noise, Dust and improper / no signalling

are some of the factors causing risk. This can be avoided by following measures:

23

Visibility defects can be eliminated by the use of visibility aids such as closed circuit

television and suitable mirrors.

Edge protection is necessary to prevent inadvertent movement.

Seatbelt to protect driver in event of vehicle rollover.

Good maintenance and regular testing necessary to reduce possibility of brake failure.

Avoid driving at the edge of roadway under construction

Heavy earth moving equipment and vehicle drivers and those giving signals should be

well trained.

5.6.5. Unstable face

Chances of Rock fall or slide exists. Regular examination of face must be done and remedial

measures must be taken to make it safe if there is any doubt that a collapse could take place.

Working should be advanced in a direction taken into account the geology such that face and

quarry side remain stable.

5.6.6. General safety measures

Provisions of the Mines Act, Rules and Regulations orders made there under shall be

complied with, so that the safety of the mine, machinery and persons will be ensured.

Permission, relaxation or exemption wherever required for the safe and scientific mining of

the deposit will be obtained from the Department of Mine Safety.

Safety kits should be located in easily accessible place with major first aid materials

in it.

Entry of any unauthorized person into mine and plant areas shall be completely

prohibited

Arrangements for fire fighting in the mine’s office complex and mining area

Provision of all the safety appliances such as safety boot, helmets, goggles, ear plugs

etc. shall be made available for the employees

Mining will be undertaken in coexistence with the requirements of the Mining Plan

which shall be updated from time to time

Handling of explosives, charging and blasting shall be undertaken only by a

competent person

Adequate safety equipment shall be provided at the explosive magazine

All the mining equipment shall be maintained as per the guidelines of the

manufacturer

Elevating the awareness of employees, contract workers and public as a whole by celebrating
