2-4: Year wise Exploration Proposed to be carried out during the ensuring
five-year period. Location of Trial pit or Bore Holes to be depicted on
Geological Scheme:-

Chapter – 3
3.0 Mining:-
It is Proposed to mine Black Granite by manual open cast method.
The mining will be continued at higher levels on East side of the existing
working Pit after leaving buffer zone along the boundary line. The mining
activity is being carried out by drilling and blasting. The workings are
carried out in two benches from East of working Pit. So it is Proposed to
rise average about 1011 m3 of Black Granite per year in the next five year
Scheme of mining period. The year wise production details are given in
Annexure – A and year wise workings are shown in Scheme of section
Plate No.-4
3.1. Year wise granite production for next five years
13
a) Year wise Development : There is a vertical and free face is available in
depth of the working pit. So that in East of the working pit area is selected to
work for next five years production. It is envisaged to produce average 10113m of salable granite blocks in each year. To raise this target production about
4573 3m of rock mass has to be mined. The site inspection reveals that the East
side of the existing working pit is suitable for development during next 5 years
programme. Most of this area is covered by the sheet rock from top to bottom
of the pit. Year wise quarry development schedule is described below and year
wise production and waste generation details are given in table No.3.
1 year: During first year operations it is Proposed to develop East side of the
existing working pit in leaving safe distance by covering the existing face into
two bench of 6 m height. The bench will be oriented in NS directions of working
pit and obtained about 1003 3m of granite blocks and 9023 3m of waste granite in
this year.
2nd year: During second year operations it is Proposed to develop towards East
side of 1st year workings leaving safe distance by covering the existing face into
two bench of 6m height. The bench will be oriented in NS directions and obtained
about 1010 3m of granite blocks and 9088 3m of waste granite in this year.
3rd year: During third year operations it is Proposed to develop towards East
of 2nd year workings in middle portion of old pit leaving safe distance by
covering the existing face into two bench of 6m height. The bench will be
oriented in NS directions and obtained about 1024 3m of granite blocks and 92183m of waste granite in this year.
4th year: During forth year operations it is Proposed to develop towards East
side of 3rd year workings leaving safe distance by covering the existing face into
two bench of 6m height. The bench will be oriented in NS directions and obtained
about 1019 3m of granite blocks and 9169 3m of waste granite in this year.
5th year: During fifth year operations it is Proposed to develop towards East
side of 4th year workings leaving safe distance by covering the existing face into
two bench of 6m height. The bench will be oriented in NS directions and obtained
about 1001 3m of granite blocks and 9007 3m of waste granite in this year.
14
During this five years operations average total rock mass of 10112 3m will
be excavated and 1011 3m of granite blocks will be recoverable from this rock
mass and remaining material average of about 9101 3m will go as mineral waste.
Any change in the Proposed method of mining Drilling Blasting and
Development of Machinery if so give details :
List of Machinery in below table:
S.No. Name of Machinery No. of machinery Power 1 KOMATSU 450 EXCAVATOR 1 246 KW 2 DC-120 ROCK DRILL 1 37 KW 3 GENERATOR 1 125 KV 4 LEYLAND TIPPER 1 100 HP 5 ATLAS COMPRESSOR 1 116 KV 6 JACK HAMMERS 2 -- 7 WIRESAW MACHINE 1 60 HP
In approved M.P it was Proposed to be carried out the mining of Black
Granite with the help of digging tools like excavator, tippers, compressors
and jackhammers are used. The Drilling and Blasting is required to quarry
the Black Granite. There is no over burden available in Proposed mining
area. The blast holes will be drilled to maximum depths of 1.5mts
depending on the bench height, by keeping burden and spacing at 3mts &
1.6-2m respectively, with the help of Jackhammer. Each hole of drilled
and blasted will be charged with 400-500 grams of explosives.
3.4 Precaution to be observed During drilling & Blasting:-
The lessee has Proposed to go for a M & S type portable magazine
to store explosives required for blasting. Blasting at shallow holes will not
cause much vibration and damage.
CHAPTER – 4
4.0 Disposal of mine waste and Separate staking of Sub-Grade
mineral (S) :-
4.1 Nature of waste and its rate of yearly generation:-
There is no topsoil in Proposed mining area for next five years. So there
will not be any soil excavation in this Scheme of mining period. During this
Scheme period 45506m3 of mineral waste, consisting of weathered
15
material will be generated during next five years. The year wise waste
generation details are given in annexure - A.
There is a stock yard Proposed in South West side of lease area near to
site services with a size of 65m length and 25 m width to keep the
production material.
4.2 Selection of Dumping Site:-
During this Scheme period the Mineral waste which is going to be
generated from the mining will be stocked on SW side of QL area in over a
length at 65 mts, width of 25 mts and to a height upto 15mts.
The Proposed dump location is shown in Plate-5.
4.3 Method of Dumping and maximum Height and spread of Dumping: During the Plan period the waste materials is being dumped on
North side of the QL area. It is Proposed to stock the waste adjacent in to
old dump on South West side over an extent of 1987 M2 as shown Plate-
5. 4.4 Precautions for confinement of dumps to prevent pollution
of surface water bodies/ Courses:-
Around the Dump a retaining wall will be constructed with the help of
waste rock to prevent the water pollution and erosion of Dumps.
4.5 Arrangement of separate staking of Sub- Grade Minerals:-
The low-grade Black Granite will be stock in the Stock Yard temporarily
and this will be sold to the user industries later. Stock Yard is Proposed in
NE side of QL area with a size of 30m length and 20m width to keep the
production material which is marked in Plate-5 &6.

CHAPTER – 8
8-0 Conceptual Mining Scheme :-
During the next five years i.e. after this Scheme period the
production will be obtained by advancing the East of the working pit
towards EW over a length of 60mts and in East-West 40m width and 6m
depth. During last 5 years at the lease period, the benches of 2nd five
years pit will be worked out. In this 5 years period the one bench of the 18
first five-year pit will be advanced towards West over a length 60mts and
to a width of 40 mts. In this 5 years lease period 45506m3 of mineral
waste will be stocked on SW side of QL area over a length of about 65 M
and width of 25m to a height up to 15mts. During 5 years about 150mts
length of North side buffer zone will be planted. At the end of the life of
the mine the waste will be used for reclamation of pit. But there will not
be any reclamation in this lease period.
8.1- Time frame of completion of mineral exploration programme in lease
area. Give broad description identifying potential areas to be covered in
the given time frame:-
No exploration in Proposal for this Scheme period.
8-2- Weather ultimate pit limit has been determined on surface geological
Scheme.
The ultimate pit limit for the lease period is marked on conceptual
Scheme of Plate –6.
8-3- Weather the site for disposal of waste rock and un-saleable or has
been examined for adequacy of land and suitability of long term use in the
event of continuation of mining activity.
The mineral waste will be stocked on SW side of QL area over a
length of about 65M and width of 25m to a height up to 15 mts. The
waste is being dumped after 5 years in non-mineralized zones of the QL
area.
8-4- Whether back filling of the pit after recovery of mineral up to techno
economically feasible depth. If so describe the broad features of
Proposals:-
In this Scheme period no back filling is Proposed because the
bottom Black Granite has to be recovered.
8-5 Post mining land use Envisaged: - If the end of the life of the
mine part of the pit will be reclamated with the waste generations from
mining and balance pit will be used for rainwater harvesting.
