Review of Compliance Position of salient Features of Mining Plan:
Exploration:
The lease area has been under mining since 1986 onwards and renewal from 2006. There
are number of pits. The mine owner drilled one bore hole for drinking water purpose. The
dolomite is exposed over the entire lease area and now the depth of workings has exposed the
dolomite from top MRL to 349 MRL i.e. 322 meters. However, from continuity, the bore for
drinking water gave column of 90 m. as reported in scheme of mining of 2012. No additional
exploration was carried out. There has been a proposal of drilling 2 boreholes for 30 m. depth in
scheme of mining. The lessee has not carried out these proposed boreholes.

8 Scheme of Mining of Malegaon Dolomite Mine
(Area: 8.094 Hect.)
Mine Development AND Production as per approved Mining Plan:
The mining/exploitation of dolomite was proposed by opencast method of mining by
developing 3m x 3m benches (Two benches) and removal of overburden i.e. soil and mining of
dolomite would be simultaneous. The lessee has developed the mine more or less as per mining
plan. The details regarding quantum of proposed development and production of dolomite over 5
years period is given below.

2010-11 2352 118 334 2000
Total 9385 470 935 7980
The total production during this period has been 13,150 tonnes as against proposed 19,950
tonnes. The production year wise during 2006-07 to 2010-11 is given below:
Year Proposed production

2009-10 5000 3450
2010-11 5000 6300
Total 19950 13150
It could be seen that only 13,150 tonnes of dolomite produced during 5 years of the
mining plan period from 2006-07 to 2010-11 against the production of 19,950 tonnes.
Waste Management:
The overburden is in the form of soil. The argillaceous intercalations as well as the
siliceous material in the form of chert, it was expected to generate waste as 10% of the ROM to
be dumped along western boundary.
Afforeestation:
It was proposed to plant 25 nos. of trees/year along boundary to compensate the damage
caused to environment by mining activity. It was reported in mining plan that lessee planted 200
trees during plan period with 60% survival rate.
Mine Reclamation:
During last five years backfilling/reclamation was not proposed as the expected mine
waste is not substantial and reserves are large enough to continue mining.

The rocks occurring in the district range in age from mesoproterozoic to quaternary. The
tirodi biotite gneiss (TBG) and supracrustal sausar group (SSG) of rocks occur in the southern
part of the district. The rocks of gondwana supergroup which occur in the north and northwest
comprise talchir, barakar, motur, bijori, panchmarhi, denwa, bagra and Jabalpur formations. The
talchir formation comprises tillite and diamictite and soft to moderately hard current bedded
sandstone with coal measures and carbonaceous shale. Motur formation comprises course grained
sandstone with pebby interbands, variegated shale and clay and the bijori formation comprises
olive and buff coloured clays and shale alternating with massive sandstone. The panchmarhi
formation consists of thick beds of course to granular, white arsenate or quartz wacked, separated
by lenses or thin layers of clast supported by conglomerate and thin red clay bands. The denwa
formation consists mainly of alternating bands of sandstone and red to variegated calcareous clay.
the bagra formation comprises of conglomerate, variegated shales and subordinate limestone
bands. The youngest Jabalpur formation consist mainly of massive sandstone alternating with

(Area: 8.094 Hect.)
The basaltic lava flows of Deccan traps, which is classified under amarkantak group are
well exposed in the eastern and southern part of the district. The group is further divided into 8
formations such as manla, dhuma, pipardahi, linga, multai, amarwara, khamla and kuleru
formations in the descending order. These flows are mainly of simple and compound pahoehoe
type, non porphyritic to porphyritic and some flows are mega porphriytic in nature. Numerous E-
W trending dykes and skills, mostly of doleritic composition intrude the gondwana rocks and
basaltic flows. They range in length from few hundred meters to few kilometers with width
ranging from few meters to few hundred meters.
The district is endowed with mineral deposits like manganese which occur as lenses
varying from 1.5 m to as much as 6m thickness in the quartz mica schist and as pockets and pods
in the pink marble.

Summary Total:
A) Proved = 32,92,375 tonnes
B) Probable = 26,15,625 tonnes
……………………………………….…………………… Total = 59,08,000 tonnes
……………………………………….……………………
Reserves under 7.5 m barrier calculated = 745,312 tonnes
Reserves calculated in the pit slope = 11,95,000 tonnes
The Bocked up reserves are = 745,312 tonnes (7.5 m barrier)
= 11,95,000 tonnes (in pit slope)
= 19,40,312 tonnes
A. Thus the net mineable reserves will be = Proved +Probable
= 59,08,000 tonnes
B. The total Bocked reserves are deducted = 19,40,312 tonnes
= 39,67,688 tonnes
Thus the reserves calculated and the net mineable reserves (Proved + probable) after
considering dolomite reserves blocked under 7.5 m barrier and pit slope are 39,67,688 tonnes
Life of deposit/mine: Considering large mineable reserves and the proposed rate of
production of 89,100 tonnes/year ROM, the life of deposit comes to 45 years.
Proposed Exploration:
The dolomite is exposed from top of the hill, down to surface level 315 MRL. It is likely
that the dolomite will persist down depth for at least 30 m. and hence the drilling of 4 boreholes at
100 m interval and down to 30 m. are proposed to confirm the dolomite persistence say upto 295
MRL. This will be done to convert 122 category reserve into 111 UNFC category. The location of
boreholes are shown geological plan Plate No. 3. The location is given below.

CHAPTER–4
4.0 CONCEPTUAL MINING:
Exploration:
There is a proposal to carry out 4 drill holes vertical for 30 m depth at 100 m. interval
from the present pit bottom. The reserves calculated are large enough to sustain the production @
89,100 tonnes/year for 3 blocks of 5 years as conceptual mining. However, the lessee will carry
out exploration during 2017-18 to know and confirm the depth persistency of dolomite.
Production & Development:
The mining will continue by open cast method of mining forming 6 m x 8m. benches. The
lease period is upto 2026.
The conceptual plan and sections is shown in Plate No.7 & 7A.
Afforestation:
The afforestation programme will continue @75 plant/year which will cover an area of
0.2250 Hect. in 1st Five year block and another 0.2250 Hect. in Second block. The afforestation
/plantation is shown in Plate No.7.
Back filling/Reclamation:
The mining will continue and reach a level upto 322 MRL. There is as such no proposal of
backfilling as well reclaim any matured pit/quarry in this mine.
Land use at the end of Conceptual Mining: The mining operations would have been
covered a large area reaching a depth upto 322 MRL. Plantation, etc. would be carried out. The
details are

5.0 MINING AND BLASTING:
Present Mining:
The lessee has been mining dolomite for the last 30 years and has developed the
developed quarry, some soil dumps and waste/reject dumps. The depth of mine has reached
324.26 m. pit depth ranging from 356 MRL to 323 MRL (min.). Surface Plan is placed as Plate
No. 5.
The total area under mining, taking all the pits into consideration is 5.4000 Hect. The land
use at present is 5.58 Hect. There has been hardly any plantation which has survived.

(1) Sufficient warning by signal is given over the entire area falling within the danger
zone & ensure that all persons within such area have taken proper shelter.
(2) Wet drilling is to be done in hand holes & as well as jack hammer drilling.
(3) Suitable air respirator will be provided to drillers. During blasting controlled blasting
will be done and not more than ten holes will be blasted at a time and no hole will be
charged with more than 400 grms. of explosive at a time.( As the case may be
Dolomite zone.
Muffle blasting will be done to prevent flying fragments, which may cause injury to local
inhabitations within danger zone. Muffle blasting will be carried out by keeping sand filled bags
on wire net placed on holes.

In spite of the fact that the grade variation in the production may arise, presently all the
grades have good marketing. So the sub grade shall be blended with the higher grade in order to
meet the specification of the end users.
Any change in proposed method of mining and development of machinery.
As discussed, the mining in the area to be done by semi mechanized method with following
machineries:
1. Drilling by Jackhammer drill.
2. Disposal of mineral rejects from mining faces to stockyard by trucks & tippers.
3. Supply of drinking water will be ensured top workers.

(Area: 8.094 Hect.)
Loading and Transportation: -
The loading of ore is being done by excavator cum loader to the dumper / tipper and the
over burden loading is done by pay loader. Further transportation to the consumption site,
dumpers are used.
Calculation for nos. of dumpers required: -
Ore to be transported (Max) = 89100 T per annum
= 297T / day
Capacity of the dumper = 30 MT
Availability of the dumper = Whole day
Minimum a Dumper will be completing 11 trips for transport the mineral from mines to
stack yard per day.
No. of Dumpers required = 297 / 30 / 9.9 = 10 Nos.
Stand by = 1 Nos.
Total no. of dumpers required = 1 Nos.
For over burden transport:
Average run of dumper site is taken both up and down travel distance would be 1 km.
minimum one hour shall be taken a Dumper for loading and un loading the waste material from
mines to Dumping yard. So a dumper will be doing 2 trips for transport the Waste from mines to
dump yard per day.
Waste likely to be generated daily 8 cum / day.
Capacity of the dumper = 5cum
No. of Dumpers required = 8/5 = 1 dumper can made 2 trips in a day.
Dumper used for the mineral will make extra for the waste/ over burden transport.
Calculation for nos. of Poclains required: -
1. Poclain availability = 85%
2. Poclain utilization = 70%
3. In 8hr shift effective working hours for a poclain
8 x 0.85 x 0.70 = 4.76 hrs or 285.6mt
4. Therefore, in one shift one Poclain would excavate 285.6/0.7 = 408 times
5. Quantity of materials carried in one boom = 2.0 MT
6. Maximum excavation expected by poclain = 408x2 x 300=248400t
7. A Poclain is targeted to excavate (297 x 300) = 89,100T per annum
8. The Projected maximum production of ore would be 89,100T per annum
Hence the nos. of Poclain required (for Ore + waste handling) is 39600/244800= 0.016t
Excavation of 10% (Av) Overburden + Mineral will require one no. of poclain.

6.0 DISPOSAL OF MINE WASTE AND SEPARATE STACKING OF REJECT/
SUBGRADE MATERIAL:
There is no doubt that a soil cover of about of about 0.5 to 1 m. However, the earlier
mining has already exposed the dolomite in all the 7 pits and has no soil section. There recovery
of dolomite has been taken as 90%. The 10% material from ROM will be mostly the shale as well
as the chert, while dolomite is exploited. All such material will be carried out from sorting plots
or from face to pre-decided waste dumps by Tippers, etc. after loading by JCB. The year wise
generation of waste is given in table below:

Total 49500
The height of dumps will be kept at 5 m and year wise it will terraced/spread for
stabilization. The little quantities of soil if generated will be used for plantation as proposed.
The lessee will construct the retaining wall for these dumps, if required, in future as the
quantities of waste every year generated are small. The terracing will be attended and some
plantation on these steps will be done to stabilize these dumps.

vi) Area under Plantation -- 0.2250
There is no water problem. There are no deep pits to get rain waters also. There is no
planning for back filling, etc.
4.2 Water Quality Management:
The water table is at high levels i.e. 20 to 25 m below ground. The necessary water
requirements for drinking to workers and for water sprinkling will be met from other source
outside lease. The potable water is available near their other mines of 3 Hect. There is no
processing unit for any toxic pollution. The water analysis report will be sent to IBM.
4.3 Air Quality Management:
The present mining of dolomite has not made any bad impact on air quality. The dust
generation is very low, no crusher near mines. The vehicles exhaust and the drilling/blasting may
pollute the air with NO2, CO, SO2. However, the SPM, RPM, APM and CO2, NO2, SO2, etc. will
be checked by Air sample analysis and measures will be adopted to keep the limit to normal.
4.4 Waste Management:
While mining the dolomite, the waste material likely to be generated as shale chips and
chert boulders and are sorted. The 10% waste from ROM is separately stacked as reject dumps
and shown on the Plate No.6, 7, EMP & PMCP. The total quantities of such reject during 5 years
will be 49,500 tonnes total.
4.5 Top Soil Management:
Though there is a thin soil cover, which has already been recovered while working in 7
pits. There will be no soil generation during 2016-17 to 2020-21 and no stacking is proposed.

4.6 Tailing Dam Management:
Not applicable.
4.7 Infrastructure:
The haul road in the lease and approach road has been developed and maintained. The
other facilities like office, rest shelters, drinking water points and blasters shade etc. will be
developed.
4.8 Safety & Security:
The necessary measures will be planned while exploiting the dolomite by maintaining
bench height and slopes. The dumping areas will be
stablised by terracing and maintaining a height of 5m. and slopes at 35o. Plantation will be done if
required for stabilizing.
4.9 Disposal of Mining Machinery:
It is not proposed and planned as the life span period of each machine deployed is not
over. The maintenance will secure the life of machine.
4.10 Disaster Management:
The lease area does not come under ant seismic zones. The small hillocks with dolomite
are stable enough. However, the land slide etc. during rainy season will be tackled. There are no
chances of floods. However, all emergency plans will be prepared and displayed on notice boards
and training will be imparted for handling such situation as routine to workers. The mock
rehearsal will be carried out. A safety and security officer will be appointed.
4.11 Care & Maintenance during Temporary discontinuance:
All those measures like fencing to working pits, collapse of dumps, etc and red flags etc
will be provided; notices displaced. i.e. All such precautionary measures will be practiced as per
MCDR, 1988 Rules and Mines Safety Rules, 1961.
5.0 ECONOMIC REPERCUSSIONS OF CLOSURE OF MINE AND MANPOWER
RETRENCHMENT:
a) Not applicable at present as the mining activity is going to continue for at least 10 to 12
years.
b) Employees will be appointed as per the lessees requirement and norms before mining
operations takes place on large scale.
c) Manpower retrenchment is not a issue and that will come up at the end of lease period or
exhaustion of the mineral reserves.
