2.5. Geology of the precise area
The proposed area of contain light to dark blue color Charnockite mainly
composed of Quartz and orthoclase feldspar with some ferromagnesian minerals. The
term charnockite in this sense is consequently not the name of a rock, but of an
assemblage of rock types. The assemblage is connected by origin, the differentiation of
the same parent magma. The banded structure which these rocks commonly present in
the field is only in a small measure due to plastic deformation, but is to a large extent
original, and has been produced by flow in a viscous crystallizing intrusive magma,
together with differentiation or segregation of the mass into bands of different chemical
and mineralogical composition.
The Charnockite is part of peninsulur gneisses, a high grade metamorphic rock of
Western Ghats. Massive formation of bluish gray colour of charnockite is also called as
blue metal or rough stone. It is suitable of construction purposes because of its high
strength, colour, high density, low porosity etc. The trend of formation is parallel to
Western Ghats and dips steeply.

Project Description
3.1. Reserves Estimation
3.1.1. Method of Estimation
The geological and Mineable reserves are estimated by cross-sectional Methods
up to a depth of 38m from above the mean sea level. Recovery of Charnockites is taken
as 95% and 5% shall be fines, mining losses and safe benches
3.1.2. Computation of reserves
The geological resources is estimated by cross sectional method is as 280079m3 of
rough stone up to a depth of 38m from the surface. Due consideration is given to depth
of mining, recovery and safety barriers etc. A detail of estimation of geological reserves
is given in Plate No.III and the mining plan.
3.1.3. Conceptual Mining Plan (Final Mine Closure)
The ultimate pit size is so designed based on certain practical factors such as the
economical depth of mining, safety zones followed, available area for mining. The
ultimate pit size of the mine in bench-wise is calculated as in table 3.3.
Table 3.3.: Ultimate Pit Dimension

Under, Reg.106 (2) (a) of MMR, 1961, the bench height is designed as 6m and the bench
width should not be less than bench height. The slope of the benches should not exceed
60° from horizontal. As far as the mining of Miner mineral is concerned, observance of
provisions of the regulations 106 (2) (a) as above is seldom due to various inherent
petro genetic and mining difficulties. The bench height is designed equal to height of
boom of the excavator. Hence, the applicant is suitably directed to obtain necessary
relaxation from the chief inspector of mines, for which provision is available within the
regulation 106 (2) (a)
3.4.2. Drilling
Drilling of shot-holes will be carried out using compressor and Jack Hammers
combination. Depth of holes shall be 1-2m.The spacing shall be 0.75m and burden shall
be 0.60m from the preface. To achieve a correct blasting geometry certain amount of
trial blast is prerequisite to effect a perfect pre-determined fragmentation and fly rock
control. In case of heavy blasting qualified mine manager has to be appointed for proper
calculation of powder factor and control blasting sequencing and arrangement of
explosives etc.

3.4.3. Blasting
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 tones per Kg of explosives. Blasting parameter
proposed to be adopted for shot holes shall be,
Depth (m) * Burden (m) *Spacing (m) = Volume (M3)
1.00 x 0.60 x 0.75 = 0.45 M3
Quantity of broken rock per hole = 0.45 x 2.6 = 1.17 MT
Blasting efficiency @90% = 1.17 x 90% = 1.05 MT/hole
Charge per hole = 140 gm of 25 mm dia. cartridge.
Quantity of rock broken per day = 69.17m3 or 173M.T.
Requirement of explosives per day = 25 Kg

Chapter-4
Environmental Management plan
4.1. Air Environment
Dust generation during drilling of shot holes, haul road, smoke from vehicles shall be
controlled by following practices:
Dust extractor or wet drilling to be followed to control dust at source of emission
during drilling.
Sharp drill bits will be used for drilling and regrinding will be done periodically to
reduce the dust generation.
Emission level in all machineries and transport vehicles to be tested once in a year
to keep them in control with proper maintenance and service as per TNPCB
Standards
Water sprinklers along the sides of haul road shall be fixed to control fly of dust
while transporting minerals and waste. Provision for automatic water sprinkle
system on permanent road and water spray by tankers on temporary road shall be
made.
Avenue trees along roads and green belt around ML boundary shall be planted as
per the norms of MoEF to control fly of dust, noise etc
Ambient air pollution monitoring will be carried out as per the regulations.
4.2. Water Environment
Depth of Mining is planned as 38m which is above the ground water table (40 m).
Therefore pumping of ground water does not arise in this mine. The turbid rain water
during rainy season is proposed to settle in a pit before discharging in to the natural
stream for settling the suspended particles.Pump having required capacity is installed
to lift accumulated rain water from working pit to the settling tank. The rain water
should be collected by garland drain around the lease boundary/pit and allowed to a
settling tank.
It shall be ensured that quality of drinking water for the worker is hygienic and
good sanitation system shall be made available.
4.3. Land Environment
Significant impact on land occurs due to change in land use pattern, degradation of soil
quality and dumping of waste. The project is site specific due to the availability of
mineral resources. Hence there is no alternative location suggested for mining.
Some of the measures followed to minimize the impacts are as follows:
The mining activities will be restricted within the lease area only.
The waste material will be utilized for the construction of road and also used by the
local people for construction work.

Consultant: Aadhi Boomi Mining and Enviro Tech (P) Ltd., Salem 42
The surface run off from the lease area will be retain within the lease and used for
plantation, dust suppression and block cutting. So there will be no soil erosion from
the lease area and its surrounding due to mining activity.
The dump will have inward slope with catch drains at inward side of the terrace and
the catch drain of the individual terrace will be connected to the garland drain
outside the periphery of the dump. Retaining wall and garland drain will be
constructed around the dumps and the surface runoff water pass through the
garland drain and finally settled in a settling pit before released outside.
Retaining wall and garland drains for the proposed waste dump will be constructed
to arrest wash offs from the dump.
Maintenance/ repair of vehicles and machineries will not be inside the mining area.
However sudden leakage of oil will be properly disposed off.
4.4. Sound and Vibration
Generation of noise during blasting shall be controlled by delay arrangements in
blasting and use of proper quantity of explosives and strength. Diesel powered
machineries, which is major source of noise in open cast mining will be properly
maintained. Attention shall be paid towards rigorous maintenance of the silencer of the
diesel engines. Protective devices shall be provided for use of persons employed in the
vicinity. Wherever the noise level is found in excess of the stipulated limits, necessary
protective devices like ear plugs will be provided to the employees exposed to such
conditions. No activity to test vibration of longitudinal waves and its peak particle
velocity.
4.5. Solid waste management
Generation of rejects and dumping of waste is discussed under chapter 3. The solid
waste shall be dumped systematically with proper repose angle and stabilization as
follows:
Gradation of dump shall be done automatically as coarser materials go to the
bottom and finer at the top and therefore drain of rain water flow freely to the
bottom without endangering the stability of dump
Stabilization of dump with top soil and tree plantation shall make the dump more
stable on long
4.6. Program of Afforestation
Local trees like Casuarinas, Teak, Eucalyptus and other regional trees etc will be
planted along the lease boundary and avenues as well as over Non-active dumps at a
rate of 30 trees per annum with interval 5m in between. The rate of survival expected to
be 80% in this area. Land use and afforestation Plan is given Plate-X. Density of trees
shall be 1000 per Hectares. The program of tree planting is given in table 4.1.

4.7. Restoration and Rehabilitation Plan
No historical monuments or area of special interest or any other sanctuaries found
around 1 km from this area. Village also located about 1km away and no dwellings
around 500m. Therefore rehabilitation of human settlement or protection of historical
places or monuments does not arise.In the event of closure of mine, the mine worker
shall get alternate work or business like agriculture etc. No serious repercussions
envisaged in the event of cessation of mining activity, as they will be provided
employment in other mines belong to the company. An amount of Rs. 1,50,000 is being
allotted Budgetary provisions for Rehabilitation of Area especially Dump Grading.
No immediate abandoned plan, being a shallow operation. S1-type of stone
fencing will be constructed around the open pit mines and watch and ward shall be to
safeguard the mine from access to surface openings
After completion of mining the land will be used as storage of rain water to
percolation that the ground water will be charged to increase ground water level. And
fishy culture will be developed with aesthetic planting around mines like park. Top Soil,
a precious product of mother earth will be made used for this rehabilitation and land
reforming.
