GEOLOGY OF THE AREA
Regional Geology:
The quarry lease applied area constitutes a part of Granite and Granitic Gneissic terrain of Archean
age. Pink and Grey Coloured Granites, Pink Alkali - Feldspar Granites are the important litho units in
the area. Grano - Diorites with basic enclaves of Supra - Crystals like Horneblende Schists, Biotite
Schists also occupy the area. These rock types are exhibiting various landforms like Domes,
Inselbergs, Castle -Koppies, Whalebacks and Linear Ridges.
The geological succession of the area as worked out by GSI (1991) is as follows:
RECENT ALLUVIUM / SOIL COVER
Younger Quartz Veins, Pegmatites Dolerites, Gabbro, Pyroxenite Dykes Fine Grained Pink Alkali Feldspar Granite, Medium to Coarse Grained Pink Alkali Feldspar Granite Granite With Mega Crysts of K-Feldspar, very coarse grained Pink Alkali Feldspar Granite
Precambrian Granitiod - Migmatite Complex
Medium to Coarse Grained Pink Granite Migmatite II Fine grained Grey Alkali Feldspar Granite Medium to Coarse Grained Grey Alkali Feldspar Granite Very Coarse - Grained Grey Alkali Feldspar Granite Migmatite I Grano - Diorite
Pink Alkali Feldspar is the most dominant rock type in the area with variations in grain size,
scattered outcrops of Migmatites containing Neosomes of medium to Coarse - Grained Grey Alkali
Feldspar Granites occurs at many places. A number of Quartz, grey and pink pegmatities and
epidote veins criss are crossing the host rock. Basic dykes of Dolerite, Gabbro & pyroxenitic
Composition traverse the granites in NW-SE, NNW-ESS,& NE-SW directions. Thin veneer of alluvium
is found limited to streams.
Geology of the area
Entire quarry lease applied area is covered with colour granite which is rising upto 30 M above
ground level, the strike length of the body measured 451 M in the area with an average width of 134
M.
Three sets of joints are recorded in the formation
1. N - S Vertical
2. E-W Vertical

3. Horizontal / Sheet Joints
Regionally the area constitute a part of Peninsular Gneissic complex of Achaean, and occupied by
Grey granite, white, grey and pink colour alaskitic granite, with patches of amphibolites,
hornblende schist bonded magnetite quartzites as enclaves in both grey and alaskitic granite.
The major litho units are extensively invaded by younger quartz, pegmatite, epitode, calcite
veins and also by dykes basic rocks.
The grey granite along with intermixing of pink alaskitic granitie forming as mounds, ridges
and hillocks in the area; contact of the rocks clearly indicate intrusive relationship, young
alaskites intruded into older grey granite; which is locally showing poorly developed foliation
trending NW - SE.
The older basic enclaves of amphibolites hornblende schist show signs of metasomatism in the
form of flakes of biotitic. Number of acidic veins like pegmatite, quartz is traversing the grey
granite trending in NNE - SSW. NE - SW to NNW - SSE to NW - SE.

Details of Mining Carried Out
The colour granite deposit is forming a hill, raised 25 M above ground level within the quarry lease
applied area.
No mining is carried out in the area as the subject area is applied for gran of quarry lease.
ESTIMATION OF GEOLOGICAL RESERVES
Geological traverses in the quarry lease applied area and the study exposures in the vicinity of
quarries facilitated to assess the shape and size of the deposit in the area. It is a mound deposit
rising 25 M above ground level within the quarry lease applied area (The lowest contour is 520 M
and highest contour is 545 M). The surface of sheet rock is wavy and irregular.
Method of Estimation of Reserves
As no detailed exploration was taken up in the area by drilling boreholes. A conservative depth of
20 M below the ground level is considered as Proved Deposit upto RL 420 and 20 M below the
Proved Category, Probable Resources are estimated upto RL 500. The exposed granite deposit is
found to be irregular in shape; the volume of the deposit is computed by Cross Sectional Area
method by multiplying the Sectional Influence to arrive the volume.
The cross sections were drawn perpendicular to the strike direction, the cross sectional area of the
individual sections are calculated to arrive at sectional area, the area thus arrived is multiplied by
the sectional influence area of 40 M (Average) to arrive the volume of rock mass.
Since the anticipated recovery of the marketable blocks and tiles may be around 25%. The same
recovery percentage is considered for extracting the dimensional stones.
The cross sections in N - S direction are drawn at equal interval of 40 M. 4 Cross Sections A-A1 - D-
D1 were drawn.
Categorization of reserves:
As no detailed exploration was taken up in the area by drilling boreholes. A conservative depth of 20
M below the ground level is considered as Proved Deposit upto RL 420 and 20 M below the Proved
Category, Probable Resources are estimated upto RL 500. The exposed granite deposit is found to be
9 | P a g e
irregular in shape; the volume of the deposit is computed by Cross Sectional Area method by
multiplying the Sectional Influence to arrive the volume.
Hence, G1 (Proved) scale category as (111) code & G2 (Probable) scale category as (122) is
calculated. No resources are considered under G3 scale of exploration.

ECONOMIC MARKETABLE RESERVES
The Colour Granite is having good export market, rough blocks free from defects like fractures, Joints,
Shears, Hair Line Cracks, Segregation Veins, Drastic Colour variation and having 120 Up Size (Gang Saw Size)
are mostly preferred by exporters and international buyers. These are known as Economic or Market
Grade (But in this quarry such sizes rarely found). The size blocks used for manufacturing of tiles generally
recovered from this quarry, which forms nearly 25% recovery of economic grade and 75% of market grade.
TOTAL RESERVES = 5, 73,096.00 M2
(a) Economic Grade (Large Blocks) 25% = 1,43,274.00 M3
(b) Marginal Grade 75% = 4,29,822.00 M3
Method of Mining (Open Cast other than fully Mechanized / Semi Mechanized):
The Colour Granite in the quarry lease applied area is exposed on the surface with boulders. Hence,
it is proposed to mine the boulders / sheet by open cast, semi-mechanized methods by developing
the bench of 3 M height each. Wire Saw cutting will be deployed based on the favourable
conditions. The development of benches in the sheet rock will be maintained @ 60° safety slopes.
The separation of blocks from the mother rock will be carried out by drilling, wedge cutting, blasting
and the excavation will be done by the machinery.
The secondary splitting, dressing of blocks will be done manually. Therefore, mining operations are
to be carried out in this area in 2 sages
1) Development
2) Production
Stage -1
The removal of weathered and under sized boulders will be cleared in lease applied area for the
next five years by using excavator.
The sheet exposed will be subjected to drilling, blasting and splitting from mother rock
Rock Splitting / Wedging:
Thus 20' x 20' to 40' x 20' to 40' mass will be separated from mother rock by drilling the slotter holes
12 | P a g e
on both sides of the mass and a top hole intersecting these two holes and wiresaw rope is passed
through and cutting is done horizontally and vertically and by this there will be mass opening on all
the sides from the mother mass.
Stage - 2
After removal of weathered and under sized boulders.
• The sheet exposed will be subjected to splitting into required sizes of blocks by using Jack
Hammers by drilling series of deep holes at right angles at regular intervals, later by
inserting feather and wedges in these holes and hammering with sledge hammer will release
the blocks.
• The boulders will be splitted to the required sizes with drilling and if required by
using chemical compound at the source only. The boulders separated will be
brought to the dressing yard for dressing.
• If the boulders, which fit into the required market grade size will be transformed into
cuboids.
Secondary Splitting:
After separation from the mother rock, it is properly checked by washing with water to identify
defects and cracks. Based on this observation, the size is decided and the blocks are marked and
separated by drilling and wedging.
The separated pieces will be examined for defects and lines, then the block or blocks are marked in
clear area and holes are drilled along the line of marking, with the help of feathers and wedges and
the waste portions are separated forming a rectangular blocks. Any bulges will be removed by
drilling and wedging making it perfect blocks. A perfect block is that all the sides shall make with
each other 90°.
Dressing
i) Dressing of dimensional rough blocks for export:
Dressing is final phase of mining operation, wherein the secondary rough blocks are
squared into regular perfect rectangular sizes, thereby avoiding uneven bulge or cavities and
other defects. Jackhammers with compressor, feather end wedges and sledgehammers are
equipments generally used for dressing the block.
13 | P a g e
ii) Dressing of rough blocks for domestic processing plant:
Dressing by means of squaring and splitting will be done for rough blocks of the size varying
between 120 x 90 x 80 and 300 x 200 x 190 M.
iii) The applicant does not possess processing plant
Drilling & Blasting
A) Drill hole pattern for smooth blasting, holes of 3 M depth will be drilled of single
row with spacing of less than 0.3 M and burden of 1.6 M or more shall be maintained
uniformly. This arrangement will yield rock size of 3 M x 2 M cross section. A bench height
of 3.5 M will be tackled.
Drilling Parameters:
i. Drill Hole Diameter 32 MM up to 3 M Long.
ii. Depth and Inclination of Drill Hole: Generally drilled vertically in an alignment,
however in primary cutting in the absence of sheet joints to develop bottom level, horizontal
holes also are drilled.
iii. Spacing and Burden
The spacing shall be about 0.1 M to 0.3 M from hole to hole and burden goes up to 1.6 M for
the splitting of the rock.
iv. Stemming & Charging of Bore Hole
Chemical Powder is used. The blast hole will be charged with 150 Grams of chemical powder by
stemming with smooth strand.
v. Explosive Type: Wherever required chemical compound is used for splitting the rock.

WASTE WATER
The wastewater generated during identification of defects/cracks in granite blocks will be recycled
back. The only source of waste water generation is sanitary waste water, which will be treated in
septic tank followed by subsurface dispersion. No further processing of Colour Granite is envisaged.
It will be directly sold to outside parties.
18 | P a g e
IMPACT DUE TO VEHICULAR TRAFFIC
Maximum an average of 12 no. of trucks per day will be required to transport granite to
outside agencies.
The existing road is capable of absorbing this additional traffic.
Dust suppression will be taken up along the haulage roads & approach roads.
Hence there will not be much impact on traffic due to this proposed mine activity. AIR ENVIRONMENT
The pollutant emitted from quarrying activity will be dust; and major sources of dust will be due to
Quarrying operations and vehicular movement. The following measures will be adopted in quarrying
to eliminate the fugitive dust emission.
PROPOSED MITIGATION MEASURES
Wet drilling.
Water sprinkling on Quarry haul roads & approach road for dust suppression.
The dust rising due to drilling will be controlled by covering the drill rods with cloth, dust
extractors will also be employed.
LAND ENVIRONMENT
ANTICIPATED IMPACTS
Due to the proposed quarrying activity, central part of the QL area shall be excavated in
order to collect useful colour granite blocks.
Granite mining will alter the physiographic scene as a large pit of 28,326 m2 with 15 M depth
will be formed at the end of plan period.
During quarrying whatever solid waste is generated shall be dumped at dumping site in Q.L.
area.
SOLID WASTE
The granite body exposed to the surface. Hence, the weathering on the surface of the rock closely
spaced joints and shears along with inherent defects like moles, dark patches and acidic veins
contribute a large extent of waste generation during the mining.
The waste generated will be dumped in the Northern side of the quarry lease applied area (Within
19 | P a g e
the quarry lease applied area) between the grids N 275 - 425 & E 25 - 225 covering an area of
11,635 M2 with an average height of 30 M with 45° slope angle will be formed. A retaining wall will
be constructed around the dump for preventing the slanting of boulders.
It is estimated that in the next five years a total of 2,55,476.25 M3 of waste is expected to be
generated with an average of 51,095.25 M3 per annum. The year wise waste generation in next 5
years is as follows:
Year Waste Generation
Rock Waste @ 75% (M3)
1st 63,733.50
2nd 57,053.25
3rd 50,728.50
4th 44,772.75
5th 39,188.25
TOTAL 2,55,476.25
AVERAGE 51,095.25
In this quarry 51,095.25 m3 of waste will be generated during development and production in 5 years
period.
Average waste generation per Annum will be 51,065.25 m3.
Total Waste generation for in Lease Period - 51,065.25 x 19 = 9,70,235 cum
The dump yard will be Northern side of the QL area.
Total Waste generation for in 5 year plan Period - 51,065.25 x 5 = 2,55,326.25 cum
