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.

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

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
