2. INTRODUCTION OF THE PROJECT / BACKGROUND INFORMATION:
(i) Identification of project and project proponent. In case of
mining project, a copy of mining lease / letter of intent should be
given.
M/s Golden Rock Export possess mining lease for production of colour
granite over an extent of 1.20 Ha in Sy.No.01 of Addukonda Village,
Tekkali Mandal, Srikakulam District, Andhra Pradesh. (Details of the
mining lease are enclosed as Annexure -1).
As the lease area is less than 5 ha. the proposed project is being
submitted to DEIAA, as per MoEF&CC Notification No. S.O.141 (E)
Dated 15.01.2016 for obtaining Environmental Clearance. Letter is
enclosed as Annexure-2
The above proposal was submitted to SEIAA/SEAC Vide letter no.
GRP/2015/1 Dated 15.04.2015. The same was examined by
SEIAA/SEAC meeting held on 29.05.2015 where in it was observed
that the project was falling in the cluster and the committee
recommended the project proponent to approach MoEF&CC. Now the
new notification was issued by MoEF&CC notification vide letter no.
S.O. 2269(E) dated 01.07.2016 where in it was mentioned that the
leases which was granted on or after 09.09.2013 does not attracts the
cluster concept. The letter is enclosed as Annexure-3.
(ii) Brief Description of the Nature of the Project.
Project is Colour Granite mine located in an area of 1.20 Ha. It is
proposed to produce Colour granite of 3,392 m3/annum by means of
Open cast Semi-Mechanized mining method using drilling with jack
hammers, blasting, manual sizing/dressing and loading into trucks.
(iii) Need for the Project and its importance to the country.
Granites are most adaptable as interior veneers in sky scrapers. In
architecture, granites are mostly used for artistic veneers as they
enrich other aspects of buildings.
In India granite is used as kitchen platform, kitchen sink, name
plates, foundation/inaugural stones etc., granites ashtrays; flower
vases and other art pieces have both domestic and export markets.
Other users for dressed or cutter shaped forms of different sizes are
flagging stones in the form of flat slabs or rectangular or irregular
shapes oversteps, walk ways, parks and terraces, parking streets and
high ways or other traffic areas with rectangular blocks.
The Colour granite has got good colour, peculiar texture and polish
taking nature. So it has got good demand in domestic and
international market. Colour Granite is exported to Chennai, Jaipur,
Bangalore and also being marketed internationally. Marketing of
Granite internationally is different as the foreign buyers for both
dimensional blocks and finished products in terms of quality,
consistent colour, polish, price etc. So there will be increased demand
in local and international market for the Colour Granite in the years
to come.
(iv) Employment Generation (Direct and Indirect) Due to Project.
The employment potential of the project would be about 28 persons.

(v) Project Description with Process details (a schematic
diagram/ Flow chart showing the project layout, components of
the project etc. should be given.
a) Type of Mining
Mining is proposed to be carried out by opencast semi-mechanized
method using Compressors, Jack Hammers, Wedges, crane, Excavator
and Tippers. Transportation of mineral will be done by trucks. The
loading of Colour Granite will be done by excavators.
Project Flow Chart
b) Brief Description (Method of working)
Opencast semi mechanized method of mining will be carried out in
this Quarry. The mining will be followed in the form of linear cut
method. This involves loosing of the primary block from the mother
rock. Hence primary cutting will be done by line drilling method where
close spaced parallel holes along straight line will be made. Line
drilling method is used for separation of primary blocks.
Drill holes of 9 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 6.0 M will be tackled in two steps. Primary
block will be cut in to secondary blocks by jack hammer drilling and
wedge cutting and this block will be dislodged from in-situ position by
an excavator.
Drilling Wedging
Manual sizing/ dressing Loading by excavators
and Transportation by trucks
Open - pit mining Waste to dumps
Back Filling
c) Drilling & Blasting
Line drilling method will be used for cutting the primary blocks which
involve drilling and blasting. The holes will be charged with chemical
compound for smooth blasting. Thus the block will separate from the
mother rock, which is pulled off from the face with cranes or shovel.
d) Removal / Excavation of O.B. and other Quarry Waste
During the Lease period of mine the total quantity of waste likely to be
generated 1,94,442 m3. It consists of granite blocks of various sizes,
shape and dimensions. Soil component will be minimal but will be
stacked separately from the mine waste.
The waste that will be generated during the mining will be dumped in
the zone separately reserved for dumping in the area. The dumps will
be designed in such that it will have slopes equal to the angle of
repose of such material. Garland drains will be provided around the
leading edge of the dump.
f) Separation of large primary Blocks from the mother rock by
pre- splitting (Primary)
For splitting the mass from mother rock, the line drilling and wedging
method will be in use with jack hammers and this waste will be
dumped at dumping yard using tipper.
The large boulders 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 burner cutters will be deployed for shaping the boulders.
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.
Thus the block will get separated from the mother rock, and then the
block will be pulled off from the face with cranes or shovel.
g) Secondary Splitting
After separation from the mother rock, block will be 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.
h) Dressing
The rough blocks obtained after primary cut will be dressed for
obtaining good geometric shape of coloured granite. The secondary
rough blocks are squared into regular perfect rectangular sizes,
thereby avoiding uneven bulge or cavities and other defects. Jack
hammers with compressor, feather end wedges and sledgehammers
are the equipment generally used for dressing the block.
i) Extent of Mechanization
Semi-mechanized mining operation will be adopted. The following
mentioned mine machinery will be deployed.
