Job No.4101802 Page - 1 Executive Summary
BRIEF OF PROJECT REPORT
1.0 INTRODUCTION
The proposed PR has been envisaged by amalgamating property of Pauni-II OC
and Pauni-III OC. The Pauni-II OC mine was envisaged in Pauni Extension
geological block located in the south-western part of eastern limb of Wardha
Valley Coalfield. Pauni Extension Block is located west of Pauni OC mine. The
area of Pauni-III OC is located west of Pauni Extn. Block, which forms the south-
western most coal bearing area of eastern limb of Wardha Valley Coalfield. The
geological block is named as “Area west of Pauni Extn. Block”. The area falls in
the Rajura tehsil of Chandrapur district of Maharashtra State. The Chandrapur
district township is located at the distance of about 25 km from the block.
The entire geological block is virgin one and no mining activity is in progress. The
nearest working opencast mine i.e. Pauni O.C. is located east of Pauni Extn.
Block.

Job No.4101802 Page - 2 Executive Summary
Presently Pauni-II OC mine is an on-going project of WCL & land acquisition is
under process. However, due to increase in land cost by Maharashtra Govt. &
new R&R Policy of CIL, it is not possible to acquire the land of this project within
the sanctioned capital. For Pauni-III OC mine, Cost Plus agreement is not
finalized till yet and so the final approval of the PR is yet to be done.

1.2 EXPLORATION STATUS
Pauni-II OC Block
Total 14 nos. of boreholes have been drilled in quarriable area (upto 120 m depth
of Composite Seam) and adjacent area of Pauni-II OC Block in an area of about
0.54 km2. The total meterage is 1558 and the borehole density works out to 26.
Pauni-III OC Block
Total 43 nos. of boreholes have been drilled in quarriable area and adjacent area
of Pauni-III OC Block in an area of about 2.17 km2. The total meterage is 3724.20
and the borehole density wotks out to 20.
The borehole density for Amalgamated PR for Pauni-II & Pauni-III OC works out
to 21 in quarriable area of 2.71 km2 (0.54 sq. km + 2.17 sq. km).
1.3 MINING ACTIVITY
The PR of Pauni-II OC mine was approved by WCL Board on 13.11.2003 in Total
Hiring Option. It is an on-going project and land acquisition is under process. No
mining activity has been started in this mine. The PR of Pauni-III OC mine is
approved on Cost Plus basis in Departmental Option and final approval is yet to
be done. Thus, no mining activity has been started in both the projects.
1.4 JUSTIFICATION OF AMALGAMATED PROJECT REPORT
Many of the existing opencast mines of Ballarpur Area (Pauni OCM, Gauri OCM)
are reaching near to its approved limits. The exhaustion of these mines would
create additional gap between Demand & Supply & therefore opening of new
projects like Pauni-II & Pauni-III OC is very essential to bridge this gap of demand
& supply. Presently Pauni-II OC mine is an on-going project of WCL & land
acquisition is under process. However, due to increase in land cost by
Maharashtra Govt. & introduction of new R&R policy of CIL, it is not possible to
complete the land acquisition of this project within sanctioned capital of PR. The
PR of Pauni-III OC has been approved on Cost Plus basis and Cost Plus
agreement is yet to be done. As both Pauni-II OC and Pauni-III OC are adjacent
PR FOR AMALGAMATED PAUNI-II & III OC (JUNE’ 2015) CMPDI
Job No.4101802 Page - 4 Executive Summary
projects, common infrastructure can be shared by both the projects thus
optimizing the capital and revenue cost. Thus, the PR of Amalgamated Pauni-II
and Pauni-III OC mine can be planned economically viable in notified price by
sharing the common infrastructure as well as by enhancing the target capacity of
the projects. Moreover, following new guidelines of project formulation have to be
incorporated in the PR.
1. Administrative cost per tonne to be considered as 10% of last audited
accounts of WCL which is Rs.16.85/t. This is as per decision of 310th CIL
Board meeting held on 08.11.2014 subject to vetting by Institute of Cost
Accounts of India.
2. In pursuant to Central Credit Rules intimated by WCL, Service Tax is to be
excluded while calculating hiring rates for OB removal / coal extraction.
3. Mid-point of Basic to be considered for estimation of salaries and wages.
4. While estimating mineable reserves, 10% geological losses and 5%
mining losses have to be considered.
Thus to make both the projects economically viable in notified price of coal by
sharing common infrastructure, enhancing the target capacity and incorporating
various new guidelines, preparation of PR for Amalgamated Pauni-II & Pauni-III
OC mines is essential.
The present proposal would work as replacement mine to depleting opencast
mines of Ballarpur Area and help in partially bridging the gap between demand &
supply of coal. The proposed PR would also help in gainful utilization of existing
men and machinery of existing OCMs after exhaustion of approved reserves of
mines like Pauni OCM, Gauri OCM etc.
1.5 SALIENT FEATURES OF PROJECT REPORT
It was desired by WCL that an amalgamated PR of both Pauni-II and Pauni-III
OC mines with common infrastructure facilities should be planned for better
economics of the two projects. Accordingly, a Project Report for Amalgamated
Pauni-II & III OC mine was prepared by CMPDI in May, 2015. The target of this
PR FOR AMALGAMATED PAUNI-II & III OC (JUNE’ 2015) CMPDI
Job No.4101802 Page - 5 Executive Summary
amalgamated mine was envisaged as 3.25 Mty (0.75 Mty of Pauni-II OC and 2.50
Mty of Pauni-III OC) & maximum possible proved reserves in both the blocks
have been considered. Only Total hiring option has been detailed in the this
Amalgamated PR as project economics is not yielding requisite IRR for approval
of PR at notified price of coal in Departmental Option & Partial hiring Option.

Job No.4101802 Page - 7 Executive Summary
1.6 CONSTRAINTS / RISK IN MINING
Major constrains / risks associated with the project are as follows:
a) Diversion of Lendi Nalla and Seasonal nala
Lendi nala is passing through coal bearing area of Pauni-III OC, which is
proposed to be diverted as per route shown in Quarry and Surface Layout Plan.
The proposed diverted length of lendi nala is 1.50 km and proposed to meet in
Sakhri nala. The seasonal nala are proposed to divert and meet in Lendi nala.
However, no capital provision has been made for diversion of seasonal nala.
b) Diversion of Sakhari Nala
Sakhri Nala is passing through coal bearing area of Pauni-II and Pauni-III OC,
which is proposed to be diverted as per route shown in Quarry and Surface
Layout Plan. The proposed diverted length of Sakhri nala is 2.00 km and
proposed to meet in Pauni nala.
c) Diversion of 66 kV power line, 11 kV power line & other rural feeders
66 kV HT line, 11 kV power line and other rural feeders passing over the quarry
area are proposed to be diverted. As per discussion with Ballarpur Area officials,
temporary diversion of 66 kV HT line has also been proposed. The temporary &
permanent diversion of 66 kV HT line has been proposed as per route shown in
Quarry & Surface layout Plan.
d) Diversion of Chincholi- Sakhri road
Chincholi- Sakhri road is passing through property of Pauni-II OC which is
proposed to be diverted. As per discussion with Ballarpur Area officials,
temporary diversion of Chincholi-Sakhri road has also been proposed. The
temporary & permanent diversion of Chincholi-Sakhri road has been proposed as
per route shown in Quarry & Surface layout Plan.
e) Land Acquisition
Land acquisition will be a major challenge. For Pauni-II OC, 21.61 ha land is
already acquired for Pauni OC mine which is to be transferred by boundary
readjustment. Acquisition of land (305.80 ha) for Pauni-II OC is in advanced
stage. For Pauni-III OC, 825.25 ha land is proposed for acquisition. Out of 825.25
PR FOR AMALGAMATED PAUNI-II & III OC (JUNE’ 2015) CMPDI
Job No.4101802 Page - 8 Executive Summary
ha land for Pauni-III OC, 12.07 ha forest land is to be acquired which is a critical
activity.
2.0 MARKETABILITY & JUSTIFICATION
The mines of WCL are under constant pressure to meet the increasing
demand of non-coking coal for power plants and other bulk consumers from
Western as well as Southern part of country. The justification of this mine has
been studied in the light of estimated demand for coal from WCL and production
forecast from existing, completed, ongoing and future projects of WCL.
Following table shows the deficit in availability of coal, including middlings from
the various Existing, Completed, On-going, and Future Projects of WCL:
Sl.
No. Sector
Projections of Surplus / Deficit of Coal (Mt)
2015-16 2016-17 2017-18 2018-19 2019-20
1 Demand for coal 69.08 69.28 70.08 70.58 70.58
2 Availability of coal 45.000 48.00 50.00 55.00 60.00
3 Surplus / Deficit (+/-) (-) 24.08 (-) 21.28 (-) 20.08 (-) 15.18 (-) 10.58
The availability of coal shown above includes the coal production from
Amalgamated Pauni – II & III OC mine. From the above table, it is clear that the
deficit in supply of coal from WCL as a whole will be (-) 24.08 Mt in 2015-16
which will be narrowed down to (-) 10.58 Mt in 2019-20 provided WCL achieved
the target of 60.00 Mt production in 2019-20. New mines/ projects have to be
opened or expansion of existing operating mines has to be done by WCL in order
to meet the ever increasing demand of coal. There is a deficit in supply of coal
from the mines of WCL and therefore a ready market exists for the coal produced
from proposed Amalgamated Pauni – II & III OC mine.
PR FOR AMALGAMATED PAUNI-II & III OC (JUNE’ 2015) CMPDI
Job No.4101802 Page - 9 Executive Summary
Thus, there will be no problem in marketing of 3.25 Mty coal from Amalgamated
Pauni – II & III OC mine in view of large deficit in availability of coal from the
mines of WCL.

4.4 DESCRIPTION OF COAL SEAMS
The details of coal seams in Pauni-Extension Block (Pauni-II Block) and West of
Pauni Extension Block (Pauni-III Block) are described below :
Pauni –II block The major part of Wardha Valley Coalfield is characterized by presence of one
thick Composite Seam varying in thickness from 15 m to 20 m composed of
mainly 2 to 3 correlatable sections separated by well defined partings. In Pauni-II
OC Mining Block, the Composite Seam having thickness ranging from 17.65 m
(CMWG-80) to 20.79 m (CMWG-118) including all dirt bands and parting occurs
in the middle part of the Barakar Formation. The study of seam structure of
Composite Seam reveals that prominent fine grained sandstone, alternate shale
and sandstone and carb. Shale, etc occurring within the seam divides it into two
sections i.e. Top and Bottom.
For proving the quarriable potentiality of Pauni-II Mining Block, both the sections
i.e. Top Section & Bottom Section of the Composite Seam have been considered
as single coal bed horizon after excluding the parting between both sections. The
details of seam description for the individual seam sections i.e. Top Section and
Bottom Section as well as for the Composite Seam in the proposed Pauni-II OC
mining area (upto 120m depth at the floor of bottom section) are as follows :-

5.1 MINE BOUNDARY DELINEATION
Pauni-II Block
The proposed Pauni-II OC Mine has been planned in Pauni Extension Geological
block which is bounded in north by fault F1-F1 (70m throw) and in south by
another fault F2-F2 (100m throw). Thus these two faults form the natural mine
boundary at the floor of coals seam of proposed Pauni II OC mine in northern and
southern side.
The top and bottom sections of composite seam subcrop in western side. The
subcrop of top section forms the mine boundary (in coal) in the western side
where bottom section also exists. The subcrop of bottom section has been
excluded because of high cut off ratio due to non-existence of top section at that

The geological block is bounded by faults in three directions & sub-crop of seam
in fourth direction. The block is divided in to five sectors i.e. ‘A’, ‘B’, ‘C’, ‘D’ & ‘E’
as detailed in para 4.6. The proposed mine is envisaged to mine coal in sectors
‘A’,’B’ & ‘C’ only, considering the geo-mining parameters, stripping ratio, etc.
Exploration is being carried out near sector ‘D’ and no geological reserves have
been projected in sector ‘E’ as it is having negligible width bounded with two
major faults.
The mining reserves in sector ‘A’, ‘B’ & ‘C’ have been considered upto dip side
major fault F2-F2 (max. depth about 200m). Faults namely F5-F5, F6-F6 & F8-F8
which exist towards east side of the property, make the eastern boundary of the
proposed mine. Reserves east of these faults (in Sector D) have not been
considered in this report as the extension of eastern side is still under geological

6.2 SELECTION OF MINING METHOD
The target of proposed quarry has been envisaged as 3.25 Mty. Production is
proposed from multi sections (two sections) of composite seam. Property of
Pauni-II OC is having limited strike length, steep gradient (1 in 6 to 1 in 7) and
property of Pauni-III OC has several faults hence, deployment of Surface miner is
ruled out in the proposed PR. Deployment of dragline has not been proposed
considering the geo-mining conditions and lesser mine life (13 years revenue
life). Underground mining has been ruled out considering conservation of coal in
thick seam and better economics in an opencast compared to underground
mining.
Presently shovel-Dumper combination is being practiced very successfully in
existing mines of WCL. Hence, in proposed Amalgamated Pauni-II & III OC mine
also shovel-dumper combination has been proposed.
6.3 EQUIPMENT SELECTION
The proposed Amalgamated Pauni-II & III OC mine has been planned for Total
Hiring option and the entire coal and OB will be extracted by hiring / out-sourcing
agency.
Some Common departmental equipment have been proposed in the mine which
are as follows :
Sl. No. HEMM (For Common) Nos.
1. Fire Fighting Truck 1
2. 8-12 t crane 2
3. 2.8 m3 Backhoe 2
4. 3.1-4.6 m3 Front End Loader 1
5. Water Sprinkler 2
6.4 MINING SYSTEM & SYSTEM PARAMETERS 6.4.1 Width & height of benches
The height of benches in OB has been considered as 10m while height of
benches in coal has been considered as per thickness of seam. However,
PR FOR AMALGAMATED PAUNI-II & III OC (JUNE’ 2015) CMPDI
Job No.4101802 Page - 24 Executive Summary
maximum height of bench in coal seam has been considered as 5 m. The width
of working and non-working benches for top overburden removal have been
considered as 30m and 20m respectively. The height of benches for parting
removal has been considered as per thickness of parting. The width of coal and
parting bench has been considered as 20m. The height and width of uppermost
two benches in OB has been considered as 5m.
6.4.2 Slope of benches & quarry
i) During mining operation The slope of topmost two OB benches in quarry has been considered as 450. The
slope of Individual OB and coal benches has been considered as 700. The rise
side quarry slope has been considered as 370 and dipside working slope of
quarry has been considered about 220 during mining operation.
ii) At the end of quarry
At the end of quarry, the slope of topmost two OB benches has been considered
as 450 whereas the slope of individual OB benches in hard strata and coal
benches has been considered as 700. Quarry slope has been considered as 370
in rise side & dip side of quarry.
It is proposed in this Project Report to carry out scientific study for slope and
design of benches in quarry. Based on above scientific study, bench and quarry
profile may change.
7.0 MINING AND DUMPING STRATEGY 7.1 CONSTRAINTS ON MINE DEVELOPMENT
Major constrains / risks associated with the project are as follows:
a) Diversion of Lendi Nalla and Seasonal nala
Lendi nala is passing through coal bearing area of Pauni-III OC, which is
proposed to be diverted as per route shown in Quarry and Surface Layout Plan.
The proposed diverted length of lendi nala is 1.50 km and proposed to meet in
Sakhri nala. The seasonal nala are proposed to divert and meet in Lendi nala.
However, no capital provision has been made for diversion of seasonal nala.

Job No.4101802 Page - 25 Executive Summary
b) Diversion of Sakhari Nala
Sakhri Nala is passing through coal bearing area of Pauni-II and Pauni-III OC,
which is proposed to be diverted as per route shown in Quarry and Surface
Layout Plan. The proposed diverted length of Sakhri nala is 2.00 km and
proposed to meet in Pauni nala.
c) Diversion of 66 kV power line, 11 kV power line & other rural feeders
66 kV HT line, 11 kV power line and other rural feeders passing over the quarry
area are proposed to be diverted. As per discussion with Ballarpur Area officials,
temporary diversion of 66 kV HT line has also been proposed. The temporary &
permanent diversion of 66 kV HT line has been proposed as per route shown in
Quarry & Surface layout Plan.
d) Diversion of Chincholi- Sakhri road
Chincholi- Sakhri road is passing through property of Pauni-II OC which is
proposed to be diverted. As per discussion with Ballarpur Area officials,
temporary diversion of Chincholi-Sakhri road has also been proposed. The
temporary & permanent diversion of Chincholi-Sakhri road has been proposed as
per route shown in Quarry & Surface layout Plan.
e) Land Acquisition Land acquisition will be a major challenge. For Pauni-II OC, 21.61 ha land is
already acquired for Pauni OC mine which is to be transferred by boundary
readjustment. Acquisition of land (305.80 ha) for Pauni-II OC is in advanced
stage. For Pauni-III OC, 825.25 ha land is proposed for acquisition. Out of 825.25
ha land for Pauni-III OC, 12.07 ha forest land is to be acquired which is a critical
activity.

7.2 MINING STRATEGY 7.2.1 Quarry & Access Trench
The proposed Amalgamated Pauni II & III OC mine has two quarries namely
Pauni-II OC & Pauni-III OC.
In Pauni-II OC, the Access Trench is proposed to touch the composite coal seam
near the sub-crop of Bottom section near fault F2-F2 (where top section also
exists). Slight variation in the position of fault F2-F2 can not be ruled out and it is
therefore proposed in this report to make confirmatory boreholes prior to making
the Access Trench to confirm the sub-crop of composite seam near the touching
point of Access Trench as well as to confirm the position of fault F2-F2.
Similarly, in Pauni-III OC, Access trench would be driven at a gradient of 1 in 16
to touch at subcrop of bottom section of seam (where thickness is 2.0m) in sector
‘A’. The Access Trench would be driven through the rise side batter to optimize
the OB excavation. Another Access trench is proposed to be driven for Sector ‘B’
& ‘C’. Part of this access trench would be common for both the sectors.
7.2.2 Cut-wise Coal, OB & Stripping Ratio
Both the quarries of Pauni-II & III OC have been divided into various Cuts. There
are six Cuts in Pauni-II quarry and ten Cuts in Pauni-III quarry. The different Cuts

As detailed above, entire mining area is divided in 2 quarries namely Pauni-II OC
& Pauni-III OC. Due to limited strike length of the quarry in Pauni-II OC and steep
gradient of seam sections, no internal dumping is proposed in the quarry and
therefore the entire overburden will be dumped externally. The layout of these OB
PR FOR AMALGAMATED PAUNI-II & III OC (JUNE’ 2015) CMPDI
Job No.4101802 Page - 28 Executive Summary
dumps are shown in Quarry and Surface layout plan. External Dump ‘D” having
dumping capacity of 25.45 Mm3 and maximum height of 90m for dumping of hard
OB of Pauni-II OC, has three benches each of 30m height and final angle of
slope is proposed to be kept at maximum 25o. It is proposed to remove soil upto
3m depth in 120m trench along periphery of proposed external dump ‘D’ to
increase the stability of dump. However, it is proposed in this report to involve
some scientific agency to conduct the study on slope stability and the final angle
of slope as suggested by the above agency will be implemented. Provision for
the same has been made in PR.
Another external dump ‘C’ on coal bearing area between Pauni-II & Pauni-III OC,
having dumping capacity of 12.80 Mm3 and maximum height of 30m at slope
angle of 370 has been proposed for dumping of Black cotton soil of Pauni-II (3.63
Mm3), part of black cotton soil of Pauni-III OC (6.24 Mm3), trench cutting OB from
the site of Dump ‘A’ Of Pauni-III OC (1.88 Mm3) and trench cutting OB from the
site of Dump ‘D’ Of Pauni-II OC (1.05 Mm3). It is proposed to rehandle entire
12.80 Mm3 of black cotton soil dump quantity in void of Pauni-III OC as shown in
Calender programme of excavation. It is also proposed to construct an
embankment (6m high above HFL & top width of 20m) against Lendi nala, Sakhri
nala, Pauni nala and seasonal nala. 2.82 Mm3 of hard OB from Pauni-II OC will
be used for construction of this embankment.
The volume of different OB Dumps for Pauni-II OC are tabulated below:

8.0 MINING SCHEDULE AND EQUIPMENT PHASING
8.1 DESIGN CRITERIA
Project report for Amalgamated Pauni-II & III OC mine has envisaged 330 days of
working in a year based on 7 days schedule of mine working. As per the
prevalent practice in WCL, there will be three working shifts in a day each of 8
hours duration. The excavation category of OB material has been assumed as
50% Category III + 50% Category IV, whereas for Coal it is assumed as Category
IV. The insitu volume weight of OB material has been considered as 2.2 t/m3
whereas for coal it is 1.60 t/m3.
8.2 ANNUAL PRODUCTIVITY OF HEMM WITH DIFFERENT LEAD
The entire coal and OB will be extracted through outsourcing agency and
therefore, the productivity of HEMM will depend on the HEMM to be deployed by
outsourcing agency. However, the lead for coal and for OB has been estimated
based on quarry and dump profile and distance of dump from quarry.
Based on the quarry profile, dump location & distance between different cuts of
quarry & dumps, the following haul distances have been assessed for OB and
coal.
Sl. No. COAL / OB LEAD

As described earlier, the entire coal and OB will be excavated by
hiring/outsourcing of equipment. The cost of OB and parting removal and coal
extraction by hiring/outsourcing of equipment depends on type of strata and lead.
In the proposed Amalgamated Pauni- II & III OC mine, the strata under
consideration is medium hard strata. The rates for OB by hiring of equipment for
the proposed mine have been estimated on the basis of FD approved rates
circulated by WCL, updated with change in price of diesel for April’2015 (Rs
53.46/litre).

Job No.4101802 Page - 37 Executive Summary
Rates for excavation for hiring/ outsourcing of HEMM are being adopted in this
report for planning purpose and economic evaluation of the project. These rates
may vary at the time of actual implementation. The rates include excavation,
transport, drilling, dozing at face & dumps, water spraying and Land Reclamation.
It is also suggested here that before awarding the work to hiring agency,
geological structure should be further confirmed by drilling additional boreholes.
Lead for OB, bench-wise, horizon-wise has been calculated for each cut on
weighted average basis keeping into account the OB dumping programme. The
lead for coal is calculated based on floor RL of each cut to coal stock yard. On
actual implementation of report these rates and lead may vary based on site
conditions. It is suggested to re-assess hiring rates again based on site
conditions while awarding tender.
8.6 DRILLING & BLASTING
Drilling pattern in overburden, with a bench height of 10 m has been envisaged
with the burden as 5.0-6.0 m and spacing as 6.5-7.0 m. The powder factor of
3.65 m3/kg has been considered for overburden for planning purpose.
For coal, depending upon the thickness available in the horizons, bench height of
maximum 5 m is being proposed. For coal bench, drilling pattern with burden
and spacing of 2.5 m & 3.0 m respectively has been proposed. A powder factor
of 5.48 t/kg has been considered for blasting in coal for planning purpose.
However at the time of operation of mine, drilling parameters have to be
optimized on the basis of actual field trial depending upon joint pattern, bedding
plane and local geology of the blast site and accordingly powder factor for OB &

16.0 ENVIRONMENTAL MANAGEMENT
Pauni-II OC mine is an on-going project of WCL and Environment Clearances for
Pauni-II OC (Capacity 0.60 MTPA) vide letter no J-11015/71/2005-IA.II (M) dated
02/02/2006 is available. Environment Clearances for Pauni-III OC is not accorded
till date. However for enhanced capacity of Amalgamated Pauni-II & Pauni-III OC
mine (Target capacity of 3.25 Mty and Peak capacity of 4.06 Mty), Environment
Clearance will be required.
Although, the target capacity of the mine has been planned as 3.25 Mty, the mine
may achieve higher or lower than target capacity under following favourable or
unfavourable geo-mining, climatic and other conditions:
i) Availability of larger or smaller strike length and flatter or steep gradient of
seam. In the proposed mine the peak capacity of 4.06 Mty is likely to be
achieved during the period from 7th year to 8th year due to larger strike
length and flatter gradient.
ii) Less or more number of rainy days in particular years.
iii) Timely and efficient working by hiring/out-sourcing agency or vice versa..
iv) Encountering less or more geological disturbances than projected in the
geological report.
v) Upgradation of size and type of HEMM at the time of replacement due to
technological advancement.
Due to above conditions, it is possible that the production from mine may be
more or less than target capacity. In case of higher than target production, the
PR FOR AMALGAMATED PAUNI-II & III OC (JUNE’ 2015) CMPDI
Job No.4101802 Page - 51 Executive Summary
higher production is catered through cushion available in the system or by
increasing workload of out-sourcing agency as departmental capacity can not be
increased for short and irregular period of such higher than target capacity.
Hence, inclusion of peak capacity in calendar programme is not feasible. But, a
peak capacity of 25% more than target capacity (4.06 Mty) is very likely in some
years of mine life.
16.1 AIR QUALITY MANAGEMENT
Air pollution is likely to be generated due to dust, exhaust from vehicles, blasting
fumes etc. In opencast mines, dust is likely to be produced during blasting,
crushing of coal, handling of overburden and coal, drilling and operation of
HEMM. The following measures have been proposed to control air pollution :
i) Water spraying is to be carried out on haul road at regular interval during
each shift.
ii) Water spraying arrangement at dust generating points in CHP, feeder
breaker, conveyor transfer points etc.
iii) Proper maintenance of all internal combustion engines to reduce smoke and
exhaust fumes.
iv) Dust extractors in working condition in all the drills
v) Tree plantation in rows and blocks along the approach road of the mine and
also along the coal transportation road on both sides.
vi) Perimeter tipping of external overburden dumps. Tree plantation on the
slope of the perimeter dump.
vii) Water spraying mixed with safe and non-toxic dust suppression chemicals
on haul roads during dry months.
viii) Coal transportation in trucks covered with tarpaulin.
ix) Avoiding overloading of trucks.
x) Frequent cleaning of coal transportation road.

16.2 WATER QUALITY MANAGEMENT
The quantity of mine water pumped out would vary according to the season. The
mine water may contain various impurities like coal dust, traces of grease, oil etc.
in various proportions. The mine water would be allowed to collect in the quarry
sump where primary settling would take place. The mine water would then be
pumped into secondary settling tanks on the surface. Here the water would be
allowed to settle and thereafter part of treated water will be utilized for meeting in
-house water requirement (like dust suppression, watering of plants, washing of
HEMM, potable use etc). Peripheral trenching is recommended near external OB
dumps for coursing the run-off and leached water from the dumps. If required, the
water may be sent to surface settling tanks before discharging it into the drainage
channels.
The used water from the industrial area comprising CHP, Workshop, Garage etc.
may be contaminated with grease, oil, coal dust, dirt etc. This water will be
allowed to settle and suitable treatment will be carried out in oil and grease trap.
Thereafter the treated water will be mostly recycled.
16.3 GROUND WATER MANAGEMENT
Due to proposed project, it is anticipated that the effect on ground water regime
will be pronounced upto around 500 m from mine edge and effect will be
pronounced in the down-dip side and milder in the up-dip side. But this effect will
be temporary in nature and once the project is over, after 2 – 3 rains, the regime
will regain its almost original status. Any shortage of water in the affected villages
during the temporary period will be supplemented through supply of treated water
pumped out from the mine.
16.4 NOISE AND GROUND VIBRATION MANAGEMENT
Existing noise level at the mine site (wrt pre-mining level) is likely to increase and
following measures are being suggested to reduce noise and ground vibration
effects :
PR FOR AMALGAMATED PAUNI-II & III OC (JUNE’ 2015) CMPDI
Job No.4101802 Page - 53 Executive Summary
i) With judicious use of explosives and correct blasting techniques, ground
vibration and noise pollution would be reduced.
ii) Structures prone to vibration or those with moving parts are suggested to be
inspected periodically and source of vibration should be damped to minimize
noise and vibration.
iii) Proper maintenance of HEMM and exhaust silencers.
iv) Vegetation barrier around the service buildings will act as effective acoustic
barrier.
v) Ground vibration and fly rock can be controlled by proper use of delay
detonators. This will help to reduce the noise pollution.
16.5 FLORA AND FAUNA MANAGEMENT
No Changes in the diversity of species or number of any species of animal and
no reduction in the number of any unique, rare or endangered species of animals
are anticipated. Any deterioration to existing fish or wild life habitat due to mining
is ruled out. Similarly, no changes in the diversity of species or number of any
species of plants and also no reduction of the number of unique, rare or
endangered species of plants are anticipated.
Adequate plantation has been proposed with native species to maintain the
diversity and also to attract the fauna.
16.6 LAND RESOURCE MANAGEMENT
Regarding land use during mining, in addition to excavation of quarry for coal,
overburden dump will be created along with development of other mine related
infrastructures. Overburden dump is proposed to be technically and biologically
reclaimed and sufficient greenery will be developed.
16.7 ENVIRONMENT MANAGEMENT SYSTEM
To have a close watch on the environmental condition and implementation of
various measures suggested, a multi- disciplinary approach is essential. At
present WCL headquarter acts as apex body which supervises the activities
relating to environment at project level through the General Manager. General
