The multi colour Granite deposits of this area is rich in orthoclase feldspar with
excellent wave pattern. It is commercially called as Red Multi. The light colour
Granite deposits of this area appears similar to Indian Jubrana. It mainly composed of
mineral constituents such as biotite, Quartz, orthoclase feldspar and less plagioclase
feldspar. It is a type of Para gneiss with alternative bands of orthoclase and dark
minerals. The biotite is fine grained and other minerals like alkaline and soda
feldspars are medium grained. The graphic texture and intergrowth of quartz and
feldspar indicates that younger intrusive was invaded into the pre-existing country
rock, which preferably would have been a biotite gneisses (Peninsular Gneisses)
which was converted into a type of a Migmatite with rich orthoclase feldspar.
Dimensional cutting and polishing of these type of hard and compact rocks exhibits an
attractive alternative bands of Light Pink and dark minerals with excellent wave
patterns.
By virtue of its excellent appearance, it find a niche in the commercial market in
the building Industry for decorative purposes in the form of labs, tiles, monuments,
cut to size, markers etc and to some extent in Engineering Industries also.

3.0 GEOLOGY AND EXPLORATION
a) Physiography :
The area applied for quarry lease is an elevated ground to a height of 5-10m from the
adjacent ground level, sloping gently towards SW. No major Pond or H.T. electric line
is found nearby. Water table is located at a depth of 24m from the surface in the open
wells in the neighbor areas. It is a waste land with rock exposure and bushes.
Temperature of the region is reported to be 30ºC to a max. of 40º C during summer.
Rain fall of this area is about 400 mm during monsoons in a year. Regional crops are
ragi, paddy and maize. There is no monuments or area of public interest are found in
the vicinity. Nearest Rail head is Hosur 38 kms from the area. Post office is available

b) Regional Geology:
Krishnagiri District is comprised of Archaean peninsular gneisses such as
Charnockites, Hornblende gneisses, Biotite gneisses and migmatites, dolerites and are
intruded by younger formations like pegmatite and quartz veins. The peninsular
23
gneiss \ migmatite consists of biotite mica, plagioclase and orthoclase feldspars and
Quartz and are found as sheet rocks running to several kms from NE –SW as a
massive rock formation.
The order of superposition of geological sequence are given as under,
Description Geological Age
Top soil - Morum (2m Thick) - Recent Age
Pegmatite and Quartz veins - Archaean Age
Dolerite Dyke - Archaean Age
Migmatites (Paradiso & Red- Multi) - Archaean “( Kolar Group)
Biotite gneisses - Archaean complex
The regional rocks mostly composed of Quartz, plagioclase feldspar,
orthoclase feldspar and accessories like mica.
c) GEOLOGY OF THE PRECISE AREA
i) Mineralogy :
The area of mining lease is comprised of Migmatite with rich orthoclase feldspar
(Light Pink). Its mineral constituents are biotite, Quartz, orthocalse feldspar and less
plagioclase feldspar. The biotite is fine grained and other minerals are medium
grained. The graphic texture and intergrowth of quartz and feldspar indicates that
younger intrusive were invaded into the pre-existing country rock, which preferably
would have been a biotite gneisses (Peninsular Gneisses). The regional flow structure
and texture of wave pattern indicates that the rock would be a type of Migmatite.
Dimensional cutting and polishing of these type of hard and compact rocks exhibits an
attractive pinkish and Brown shades of background with less wave patterns. It is a
part of Peninsular gneisses migmatised by younger intrusives. It is commercially called
as Red-Multi by the buyers in view of its rich assemblages of light Pink feldspar. It is
Multi colour granite covered partly by Morum soil at the top. The rock is hard, compact
and sheet in nature so as to cut required sizes of blocks. The mineral constituents of
24
the rock mass shall be about Orthoclase feldspar 45%, quartz roughly 20%,
Plagioclase feldspar 15% , mica 15 % and others 5%.
Dolerite dyke is found about 6m away on the NW side of the lease area trending in
west to east direction.
ii) Geological setting and structure
The order of geological sequence are,
Description Geological Age
Top soil - Morum soil (Intermittent) - Recent
Dolerite Dyke - Arcaean
Migmatite (Red Multi) with wave pattern - Archaean
Biotite Gneisses (Peninsular Gneisses) - Archaean
The top soil cover is found on lower elevation of the area but on the higher elevations
fresh massive migmatite are exposed on the NE and eastern sides. The strike of the
granite body is almost NE-SW and dips vertical. The regional trend is shown in the
geological plan. The multi colour granite that occur in this area is massive with less
boulders or fractures. It is suitable for commercial exploitation of gang saw size rough
blocks.
The following photograph illustrates the nature of granite formation in this area,
25
Fig.9 Shows massive sheets of red multi granites on NE side
d) DRIANAGE PATTERN: No drainage is found nearby.
e) EXPLORATION
i) Already carried out:
No exploration was carried out as the outcrop occur as massive sheets. It is shown in
the geological map drawn in 1: 1000 scale (Plates III).
ii) Propose to be carried out :
As outcrops are very well exposed at the surface. It does not required any detailed
exploration like drilling, pitting etc. to delineate the rock body. Necessary mining
geological details can be observed during mining by employing a Qualified Geologist to
identify the texture and structure of geological formations for proper extraction of
blocks and orientation working faces to minimise the wastes and to increase the
recovery. However it would be advisable to drill two core drill holes to confirm the
26
colour, massiveness of the formation at depth for long term investment decision
making.
f) METHOD OF ESTIMATION OF RESERVES
The geological and mineable reserves are estimated by cross-sectional method.
Since the granite band is occur widely over the entire area and dips vertically and
further exposed in the working pits, the depth of mining is taken as 18m from the
surface. Leaving the top soil and boulders , the average thickness of granite available
for extraction is 18m. The following recovery rate is taken for estimation of reserves
based on field conditions.
Bench Height (m) Depth(m) Recovery
Bench 2m 0-2 0%
Slice or Bench II-IV 6m 2-18m 20%
g) GEOLOGICAL RESERVES
The geological reserves is estimated for the area allowed for mining by the Cross-
Sectional method is as 29484 cubic meters up to a depth of 18m , having considered
the depth of mining, recovery, safety barriers etc. Details of estimation of geological
reserves is given in the Annexure I.
h) MINEABLE RESERVES AND ANTICIPATED LIFE OF MINE
The mineable reserves is estimated by cross-sectional method having considered
the recovery factor, depth of mining, safety barriers etc., The mineable reserves is
estimated as 20930 cubic meters. Details of estimation of mineable reserve is given
in Annexure II.
The overall pit slope is taken as 60 deg. from the horizontal. The recovery factor is
taken as 20% for benches II-III(2-18m ) depth based on the field experience of
adjacent mines. Depth of mining is taken as 18m from the ground level.
The life of the mine is computed as 52 years at a production rate of 400 cubic
meters per annum.

4.0 MINING
a) Proposed Method of Working:
Open cast method of Semi- mechanised mining shall be adopted to extract the
dimensional blocks of required size from this area. It is proposed to form benches and
road as per Plates VII-X. Man power and machinery to be engaged are discussed in
later chapter.
b) Year Wise Production and Development for the first five Years :
The development involves only removal of small amount of top soil and Rejects
amounts to 80%. The annual production is proposed as 400M3 for the first five years
and generation of rejects are shown as under,

d) OPEN CAST MINES
i) Mode of Working :
The Granite blocks of the following standard sizes will be extracted from this mine
by Open cast semi-mechanised method of mining using Shot hole drilling with a aid
of compressor and Jack hammers ,smooth blasting, block lifting using cranes and
waste and rejects removal using Hydraulic excavators and tippers combination.
Working plans and sections showing the layout of faces and direction of mining are
given in Plate VII-X.
The economical depth of mining is taken as 18m having considered several field
phenomenon such as limit of lease boundary. Three benches are designed to exploit
the granite blocks by conventional methods. The benches each of 6m height and width
not less than the height are designed to win the blocks.
BENCH DESIGN PARAMETERS :
Top soil shall be removed and stacked separately along Lease boundary as
earth Bund which will be used for afforestation purposes in phases. Granite benches
will be formed to a height of 6m and width not less than 10m for movement of
machineries while working and the final slope shall be 60°. Initially the granite
benches will be vertical for dimensional cutting of blocks. The applicant is proposed to
produce dimensional blocks to measure ,
Minimum size = 1.50 x 1.00 x 1.00 m = 1.50 cu.m.
Maximum size = 3.40 x 1.90 x 1.80m = 11.62 cu.m.
Construction of parapet as a fencing around such ultimate pit limit on top of opencast
workings will be arranged to safeguard the mine from inadvertent entry and hazards.

PRE-SPLITTING :
Preface development is must for extraction of dimensional blocks without cracking
or fissuring of the body during drilling and blasting . To achieve such preface a pre
splitting technique using Jet burners on the advanced direction are resorted to a
distance of 6 –10m so as to isolate the working face from the remaining area. This
practice are followed to minimise the formation of artificial cracks and tensional
fissures that are developed after blasting in the advance direction.
Shot - hole drilling with jack hammers and line drilling with top hammers will be
used at close spaced intervals to develop cracks along the line of drilling and to open
the blocks. Low strength explosives or merely detonating fuse may be used to create
a “pre-determined line of cracks “ so as to pull out the blocks from the working
faces.
Block - Lifting is an art to remove the cracked rough block from the face by a
Crane/Excavator. The debris and rejects and waste will be cleared from the face by
Hydraulic Excavator and tipper combinations. The rough blocks will further subjected
to dressing to a desired size by secondary cut at the surface.
The rough dimensional blocks will be supplied to the potential domestic and
overseas customers. The waste will be dumped on the specified place earmarked for
dumping as shown in the Plate VII-X.
32
e) EXTENT OF MECHANISATION
The machineries proposed to engage in the mines for systematic operation and
development of quarry to augment extraction of blocks are in Annexure IV.

b) Fauna:
The fauna of the area is represented by rabbits and Fox. Rabbits are common in
this area. No sanctuaries or wild life is found nearby.
iv) Quality of Air, Ambient Noise level and water
Being a small area the Ambient Air Quality is not tested by the applicant. There is
no heavy Industries nearby, the noise level of the area will be as same as the regional
level. More over the noise level measurements does not raise for this area since very
low explosives will be used for mining and the machineries to be used shall hydraulic
types, it does not create much noise except the compressor, drilling and jet burners.
Water drawn from the tube and open wells are potable and the villagers are
using such water for a long period. No adverse health hazardous was reported due to

vii) Public Building Places of worship and Monuments:
No infrastructures like residential building, places of special interest like temples,
architects, Sanctuaries etc., are found around 5 kms radius.
b) ENVIRONMENTAL IMPACT ASSESSMENT (EIA)
Being a small mine impact of mining on environment will be negligible. There is
no chance for cutting of trees. On the other hand the applicant propose to plant more
trees as per the mining plan. There will not be any change in the quality of water to be
47
pumped from the mines during rainy season. Wherever the noise level is found in
excess of the stipulated limits, necessary protective devices like ear plug, mask will be
provide to the employees exposed to such noisy and dusty conditions. In addition,
dust will be controlled at the source by wet drilling, periodic spraying of water over
haul roads, etc The mining operation will provide more employment to the rural
people and environment friendly operations. It impact on environment will be
minimum or negligible. However generation of noise should be controlled or adequate
protective devices should be provided for use of persons employed in the vicinity.
c) ENVIRONMENT MANAGEMENT PLAN
i) Dust: Dust expected to be generated from drilling, hauling roads, place of
excavation etc will be suppressed by periodical wetting of land by spraying using MgCl2
solutions. Wet drilling and dust extractor arrangements will be provided to drilling
units so as to control raise of dust from the site of drilling. Operators, those exposed
directly to such conditions will be provide such protective equipments like mask, ear
plug, helmet, gloze etc as per the Mines Act.
ii) Temporary storage and Utilization of Top Soil :
Small quantity of Top soil shall be dumped separately for dump afforestation in
future.
iii) Proposal for reclamation land affected by mining activities during and at the end mining lease period:
The depth of granite deposit is not known. However for economical planning, the
depth is taken as 18m from the surface. Immediate reclamation of land does not raise
for this deposit. However it pit will be used for miscellaneous purposes like fish bond
etc., after completion of mining. All waste and reject materials will be dumped as per
the mining plan.
iv) Programme of Afforestation:
Regional trees like Casuarinas. Eucalyptus, Neem, acacia ,Tamarind etc will be
planted along the Lease boundary and avenues as well as over Non-active dumps at a
48
rate of 20 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.
v) Stabilisation and Vegetation of Dumps:
The materials to be dumped shall be very hard in nature and it does not require any
grading separately. The materials like granite rejects shall be graded automatically
during dumping by Excavator and tipper combinations. Part of top soil will be spread
over the Non-active dumps along the slope and edges to plant tree sapling to form
vegetal cover over the dumps. Such vegetal cover will prevent erosion of dumps
during rainy seasons. The program of tree planting is given as under,
Year Place Type of Trees Number rate of survival
I Lease Boundary Neem,acacia, Casuarina, 20 80
Eucalyptus, Tamarind etc.,

vi) Treatment and Disposal of water from mines :
The water to be pumped from the mine will pure and potable. It will not be
harmful and it does not require any treatment before discharging into the natural
course or tanks. Granite sheet extraction will not produce any waste which will pollute
the ground water. Drinking water to mine labour will be supplied from public source or
bore well to be drilled by the applicant.
vii) Measures for minimizing adverse affect on water regime :
The water to be pumped out will be very pure and potable and therefore it will not
affect any water regime s of the area. Depth of mining is also moderate and it does
not affect even the ground water table.
viii) Socio-economic benefits arising out of Mining:
49
The mining operation will create an employment of about 29 persons, of which 80 %
will be from local people (Son of Soil). After development of mine from this area, not
only provide employment opportunities but also the industrial culture and civilization
to the village people. Beneficiary villages are Sandanapalli and its hamlets
12.0 ANY OTHER RELEVENT INFORMATION
The Light colour granite of this area is commercially called as Red-Multi. But
geologically, it is type of Migmatite rock intruded in to the pre existing country rock.
The geological reserves and mineable reserves are estimated as 29484 and 20930 m3
respectively for the lease area up to a depth of 18m. Systematic mining with proper
orientation of working faces and blasting techniques will improve the recovery, by
which the mining cost will be so low from the present status of mining; also the
valuable rock will be conserved. Engaging Diamond wire saw cutting machine will
improve the rate of recovery to more than 20%.
Diamond wire saw cutting shall be followed for massive sheets of rocks where the
formation having less cracks or fissures.
