Geology:
Physiography:
The quarry lease area is located on a part of plain land. The area is unfit for agriculture and
surrounded by black galaxy granite quarries. The drainage network is due West & SW.
Musi river flows at the distance of 4.6 Km due SW of the quarry lease area.
Topography:
The quarry lease area is a part of plain land raised about 1 m above ground level within the
quarry lease area with topo relief in South direction. The lowest contour is 200 M and
highest contour is 201 M in topo plan.
Regional Geology:
The quarry lease 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
Horneblend Schists, Biotite Schists also occupy the area. These rock types are exhibiting
various landforms like Domes, Inselbergs, Castle -Koppies, Whalebacks and Linear Ridges.
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
Pegmatites and Epidote Veins are criss crossing the host rock. Basic dykes of Dolerite,
Gabbro & Pyroxenitic Composition traverse the granites in NW-SE, NNW-SSE, E-W & NE-
SW directions. Thin veneer of alluvium is found limited to streams.

Local Geology:
Regionally the area constitute a part of Peninsular Gneissic complex of Archean, and
occupied by Porphyritic granite, white, grey and pink colour alaskitic granite, with patches
of amphibolites, hornblend schist bonded magnetite quartzites as enclaves in both
prophyritic and alaskitic granite.
The major litho units are extensively invaded by younger quartz, pegmatite, epitode, calcite
veins and also by dykes basic rocks.
The porphyritic 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 porphyritic granite; which is locally
showing poorly developed foliation trending NW - SE.
The older basic enclaves of amphibolites hornblend schist shows signs of metasomatism in
the form of flakes of biotitic. Number of acidic veins like pegmatite, quartz is traversing the
porphyritic granite trending in NNE - SSW, NE - SW to NNW - SSE to NW - SE.
Reserves:
The Geometry of the Deposit:
The geological traverses on the outcrops and the exploratory mining was facilitated to have
shape and size of the deposit in quarry lease area. The black galaxy granite deposit is
occurring as in the form of large boulders and sheets below ground level.
Method of Estimation of Reserves:
The deposit is exposed in 4 m below surface and hence cross sectional method is adopted
for Estimation of Geological Reserves. 4 Sections A-A1 & D-D1 were drawn across the
quarry lease area in the strike direction of the dyke to estimate the reserves.
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
multiplied by the appropriate sectional influence of 40 M (Average) to arrive the
volume of rock mass. A conservative recovery of 30% rough blocks is considered in
estimation.

Categorization of Reserves:
As no detailed exploration is conducted by boreholes, only exposed resources are
considered for Reserve Estimation upto RL 150 M.
Hence, only G1 (Proved) scale category as (111) code is calculated. No resources are
considered under G2 & G3 (Probable & Possible) scale of exploration.
Hence, the exposed deposit is proved category of reserves as 111 coding (Proved) under
UNFC guidelines.
The deposit upto RL 150 is considered as Proved Reserves.

Method of Mining (Open Cast other than fully Mechanized / Semi Mechanized):
The Black Galaxy Granite in the quarry lease area is exposed sub-surface. (Hence, it is
proposed to mine sheet by open cast, semi-mechanized methods, by developing the
benches of 6 M height in 2 phases of 3 M 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 excavation will be done by the machinery.
The secondary splitting, dressing of blocks will be done manually. Therefore,
mining operations have to be carried out in this area in 2 stages.
1) Development
2) Production
Stage - 1
The sheet 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 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.
Environmental Management Plan
9
• The large boulders will be subject 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 splited 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 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:
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.
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 Cm and 300 x 200 x 190 Cm.
Drilling & Blasting
Drill hole pattern for smooth blasting: Holes of 3 M depth will be drilled in a 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.
Environmental Management Plan
10
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 horizontal holes also are drilled to develop bottom level.
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
Gun Powder is used. The blast hole will be charged with 150 Grams of explosives by
stemming with smooth strand.
v) Explosive Type
For primary blasts pre-splitting 8 - 10 inches spacing 32 mm dia. Jackhammer holes
perfectly aligned along the desired plane are drilled. They are charged with gun
powder and detonating cord or gelatins with detonating cord with sufficiently packed
stemming column that gives a cut plane along the desired one. (Nitrate Mixture &
Detonators are used).
