CHAPTER – 1

INTRODUCTION

1.0 BACKGROUND OF THE REPORTThe Gevra OCM is an existing mega opencast project in the thick seam zone

of Korba coalfields in SECL command area. It is under the administrative control of

Gevra Area of SECL. The Project Report for Gevra Expansion Opencast Project

(25.0 to 35.0 Mty) was approved in June 2010 for a normative production of 35.0

Mty. Presently, Gevra Expn. OCM is having Environment Clearance for a peak coal

production of 41.0Mty against the normative production of 35.0 Mty. The mine has

achieved the coal production of 41.0 Mty in the year 2015-16. Recently the Project

Report for Gevra Expansion Opencast Project (35.0 to 70.0 Mty) was approved by

CIL Board on dated 5th March 2016.

Based on “Road Map for Enhancement Coal Production of CIL” the target of

SECL for the year 2016-17 has been projected as 149.70 Mt. To meet this growth in

production of SECL in the year 2016-17, Gevra OC has been identified for

enhancement of production from peak production of 41.0 Mty to proposed

normative production of 50.0 Mty due to unavoidable delay in opening of other new

projects.

Accordingly this mining plan for enhancement of production from 35.0 Mty to

50.0 Mty has been prepared to produce 50.0 Mty of coal from Gevra Expn.

Opencast Project. As on 01.04.2016, the balance coal within the approved quarry

boundary is 568.86 Mt and balance OB within the approved quarry boundary is

947.76 Mcum. Based on this balance coal and OB the revised production

programme has been worked out to estimate the required OB quantity to produce

the proposed production of 50.0 Mty. As per the revised production programme the

balance life of the project works out to about 12 years considering normative coal

production of 50.0 Mty.

1.1 ENVIRONMENTAL CLEARENCEPresently, under sec 7(ii) of EIA Notification 2006, Gevra OCP is having

Environment Clearance for a peak coal production of 41.0Mty for an area of


---------------------------------------------------------------------------------------------------------------------------------------2

4058.146 Ha of land issued vide letter No. J-11015/85/2010-IA-II(M) DT. 06-02-

2015.

The proposed mining plan for enhancement of production from 35.0 Mty to

50.0 Mty, EMP would be prepared for a normative coal production of 50.0 Mty,

within the area of already acquired 4184.486 Ha land.

1.2 PREPARATION OF MINING PLANThe mining plan for enhancement of production from 35.0 Mty to 50.0 Mty has

been prepared in three parts, which are as given below

1. Coal production programme: To deal with enhancement of coal production

to 50.0mty.

2. Despatch capacity: To have dispatch arrangement for the proposed

enhancement of coal production.

3. Time line for gradual shifting of the mine production to 70Mty (Peak

production 87.5Mty) as per the Approved project report of Gevra OC

Expansion (35.0-70.0Mty).

The mining plan has been prepared as stop gap arrangement to produce

50.0 Mty of production to cater the increased production of SECL. All efforts would

be made to acquire the additional land and obtain EC as soon as possible so that the

mine produces 70Mty as projected in the PR, preferably within 3 years time.

CHAPTER – 2SALIENT FEATURE OF APPROVED PR

OF GEVRA OC EXPANSION (35.0-70.0 Mty)

2.0 APPROVED REPORTSProject Report for Gevra Opencast Project for an annual capacity of 6.00 Mt

of coal was prepared by CMPDI in March 1979. This was to meet the coal

requirement of Korba Super Thermal Power Stations (KSTPS) of NTPC (first stage)

for 1100 MW, amounting to about 4.25 Mty of coal. The excess capacity was

envisaged to meet a part of the demand for expansion of KSTPS by 1000 MW.

However, the Government approved the Project Report in December 1979 for an

annual capacity of 5 Mt at an estimated capital of Rs.50.08 crores.

Later, after the approval of Gevra Opencast Project, coal clearance was

given to NTPC for expansion of the MSTPS by 2 x 500 = 1000 MW. Thus, the total

capacity of the power house became 2100 MW and the ultimate annual coal

requirement was estimated at about 8 Mt. PR for Gevra Opencast Project

(Expansion) was prepared in March 1982 for an annual production of 10.0 Mt, to

meet the ultimate requirement of coal of KSTPS and to bridge the general shortfall of

coal supply in Western India. The report was approved by Government of India on

18.9.85 for a capital investment of Rs.224.39 crores.

In the year 1992-93, a scheme for Gevra OCM was prepared for

augmentation of production by another 2.0 Mty with a proposed capital investment of

Rs.39.62 crores. This scheme was sanctioned on 19.9.92 by CIL Board. The

balance reserves as per the scheme (as on 1.4.92) were estimated as 496.31 Mt.

The corresponding OBR was estimated as 533.79 Mcum at an average stripping

ratio of 1.08 cum/t. (The scheme incorporated the additional provision of HEMM for

removing the additional volume of overburden. The balance life of the project was

estimated as 42 years at the enhanced capacity of 12 Mty). The scheme was

declared completed on 31.3.95.


---------------------------------------------------------------------------------------------------------------------------------------2

A capacity augmentation scheme for Gevra CHP (from 10 Mty to 12 Mty)was also prepared and sanctioned on 31.7.92 for a capital investment ofRs.13.63 crores. Thus, the total sanctioned capital for Gevra OC (12.00 Mty)became Rs.277.64 crores (Rs.224.39 cr. + Rs.39.62 cr. + Rs.13.63 cr.).

The Project report for Gevra O/C Expansion (25 Mty) was prepared byCMPDI and approved by GOI on 12.07.05. Working group/X Plan document hadindicated the demand of non-coking coal for XI Plan as 580 Mt and indigenoussupply of non-coking coal from CIL as 445 Mt. The updated production of May 2005have indicated the demand of non-coking coal for the XI plan as 622 Mt andindigenous supply of non-coking coal from CIL as 508 Mt. Projection of totalindigenous supply of non-coking coal as 562.32Mt leaves a gap of 59.68 Mt forwhich Emergency Coal Production Plan of CIL has been formulated.

Gevra Opencast has been identified as one of the project in the EmergencyCoal Production Plan of CIL. Thus the Expansion project report (25.0-35.0Mty) forGevra OC was prepared. The incremental capital estimated for Project Report (25 to35 Mty) dated October 2006 was Rs.618.16 crores. The updated capital estimatedfor the approved project was Rs.1008.12 crores in the month of September 2009.The salient features of this sanctioned Project Report (25-35 Mty) project is asfollows:-

Date of sanction - 01.06.2010

Gradient - 1 in 6 -1 in 12


---------------------------------------------------------------------------------------------------------------------------------------3

Due to increase in the demand for power grade coal, Gevra OC has been

identified as one of the coal mines where production can be enhanced. Moreover, it

has been projected that SECL as a whole has to produce 250Mt in the year 2019-20.

As such it was decided to prepare an Expansion project report for Gevra OC

and the same was included in the Annual Action Plan for the year 2014-15.

The Project report was prepared to enhance the capacity from 35.0Mty to

70.0Mty and the same was approved by CIL Board on 5th March 2016 for a

estimated additional capital investment of 9943.55 crores.

2.5 COAL TRANSPORT SYSTEM AS PER APPROVED PR

2.5.1 Present System of Coal Handling & Dispatch

Silo No.1&2 with storage capacity of 2400 te each are the existing silos of the

Gevra project. These silos are working with MGR system for delivery of coal to NTPC

Korba. Both, J-K series and L/R stream of belt conveyors feed coal to Silo No.1&2 via

a 30000 te ground bunker with C-series of conveyors and a 5000 te surge bunker

respectively. Thus, the existing silos with J-K series and L/R stream of belt conveyors

are engaged in dispatch of coal to NTPC Korba only. Coal from both Lower

Kusmunda and Upper Kusmunda seams comes to the existing silos through the J-K

series and L/R stream of belt conveyors. Designed coal handling capacity of this

system is 15 Mty.

There are five number of sidings with wharf wall loading system in the project.

Junadih Siding Nos. I&II are used by SECL for dispatch of coal to various consumers

whereas Siding Nos. III&IV (ACB sidings) and Siding No. V (GEB siding) have been

leased out to the washery holders for dispatch of washed coal by them. Each wharf


---------------------------------------------------------------------------------------------------------------------------------------6

wall siding has coal handling capacity of around 5 Mty. In addition, there are eight

number of mini CHPs with Feeder Breaker/ crusher and road weigh bridges for

dispatch of coal to various consumers by trucks through road sales.

2.5.2 PROPOSED COAL HANDLING AND DISPATCH SYSTEM2.5.2.1 In-pit Conveying System (Central Sector)

Coal won by surface miners in the lower Kusmunda seam will be transported

by two pairs of series of belt conveyors viz. J-K series and A-B series located in the

central corridor left for belt conveyors and haul road in the central sector.

J-K Series : J-K series will consist of conveyors J1/K1, J2/K2, J3/K3, J4/k4, J5/K5

and J6/K6. All the conveyors of this series will be with 1600 mm belting. Modified

J1/K1 & J32/K2 and new J3/k3 is expected to be commissioned by the end of 2015.

Conveyors J4/K4, J5/K5 and J6/K6 will be additional provision for the 70 Mty

expansion project and will be installed in phases. Accordingly, the truck receiving

station at the tail of conveyors J3/K3 will be shifted at the tail of the last pair of

conveyors. Each of J and K series will be of 2300 TPH capacity. One of them will be

working while the other will be stand by. However, in case of peak demand or failure

of other circuit, both J and K series may be required to run simultaneously.

A-B Series : A-B series will be a new set of conveyors consisting of A1/B1, A2/B2,

A3/B3, A4/B4 and A5/B5 conveyors with 2000 mm width belting and 5000 TPH

capacity. A-B series will be installed in the central corridor adjacent to the J-K series.

A series and B series will parallel to each other. One of the A and B series of

conveyors will be working while the other series will be stand by. However, in case of

peak demand or failure of other circuit, both A and B series may be required to run

simultaneously. Conveyors A1/B1, A2/B2, A3/B3 & A4/B4 will be installed in the first

phase whereas conveyors A5/B5 will be installed at a later stage. Conveyors A4/B4

will be fed by shiftable conveyors from the face. However, conveyors A4/B4 will be

directly fed by Chain Feeders installed near the tail of the conveyors which will be

shifted to the tail of A5/B5 after its installation at a later stage. These Chain Feeders

will be partially used to receive coal from the nearby locations by trucks and will be

fully utilized in case of any breakdown in the shiftable conveyors circuit. Conveyor A1

will discharge coal either on TH-2 through a fixed tripper or on the existing L-series of

conveyors of 1400mm belt width and 3 m/s speed, whereas conveyor B1 after

crossing the L-series will discharge coal to conveyor B0 of 2000 mm belting and 5000


---------------------------------------------------------------------------------------------------------------------------------------7

TPH capacity. Conveyor B0 will discharge coal through a two-way chute to the tripper

conveyors D7/D8 over the 50000 te overhead RCC bunker of the western circuit.

Shiftable Face Conveyors : Shiftable conveyors S1, S2 and S3 will be installed in

series at the face for transportation of coal from face to A-B series of conveyors. S1

and S2 will be of fixed length whereas length of S3 will vary according to the position

of the conveyors S1 and S2 with respect of the transfer point at the A-B series of

conveyors. Conveyor S3 will be provided with a radial swiveling belt conveyor S0 with

discharge chute which can be set to discharge coal onto either A or B conveyor. The

radial swiveling belt conveyor for transfer of coal from conveyor S3 to A or B conveyor

will be shifted from A4/B4 conveyors to A5/B5 conveyors after few extensions of the

shiftable conveyor S3. After installation of conveyor A5/B5, orientation of conveyor S3

may change and it may also become almost in-line with S1 and S2 conveyors. In that

case, location of the two truck receiving stations at the coal face may be spread out to

bring one of them nearer to S3. All the shiftable conveyors will mounted on slippers

and rail tracks will be laid along the conveyors to facilitate their shifting. Shifting of the

conveyors will be done with the help of crawler mounted conveyor shifting machine.

Coal won by surface miners will be loaded into trucks by pay loaders and dumped into

Chain Feeders of about 2000 TPH capacity. Two number of Chain Feeders will be

provided with each of the shiftable conveyors S1 & S2 for receipt of coal from the

trucks (Ref. Plate No. M6). Three out of the four Chain Feeders will be working

whereas one will be stand by. In case of concentration of coal winning in a smaller

patch, all the three working Chain Feeders may be deployed to discharge coal onto

either of S1 and S2 conveyors. Shifting of the conveyors S1 & S2 along with the

Chain Feeders and extension/shifting of the conveyor S3 will be done to maintain a

minimum clearance between the OB dump and the conveyors and an optimum lead

for the tipping trucks.

2.5.2.2 Surface Conveying SystemTwo circuits of surface belt conveyors along with bunkers and silos have been

envisaged along the western and eastern boundaries of the mine in the western and

eastern sectors respectively for transportation of coal won by surface miners in the

Upper Kusmunda seam and other upper seams viz. D (Bottom) & D (Top) seams and

E, F & EF seams. Coal from the face will be transported by trucks upto the truck

receiving stations of both the circuits.


---------------------------------------------------------------------------------------------------------------------------------------8

2.5.2.2.1 Western CircuitWestern circuit of surface conveyors will consist a truck receiving station

with two sets of 5 x 8m x 8m x 120 te steel hoppers (4 working & 1 standby) along

with 1000 TPH vibratory feeders, two series of belt conveyors (D series) of 2000 mm

belting parallel to each other, one overhead RCC bunker of 50000 te capacity and two

silos of 4000 te capacity each. One of the five hoppers in each set will be standby

One series of surface conveyors will consist of conveyors D1 & D3 whereas the other

series will consist of surface conveyors D2 & D4 of 4000 TPH capacity each. One of

them will be working while the other will be stand by. However, in case of peak

demand or failure of other circuit both the series may be required to run

simultaneously. Conveyors D3/D4 will discharge coal onto the tripper conveyors

D5/D6 of 5000 TPH capacity each over the 50000 te bunker. Coal from the bunker will

be reclaimed by plough feeders of 5000 TPH capacity and will be discharged onto the

reclaim conveyors D7/D8 of 5000 TPH capacity each. Two number plough feeders will

be installed over each of the two reclaim conveyors D7 & D8. Conveyors D7/D8 will

discharge coal into Silo No.5 through two-way chutes. Conveyors D9/D10 of 5000

TPH capacity each will receive coal from the two-way chutes at Silo No.5 and

discharge it to the adjoining Silo No.6. Both the silos i.e. Silo No.5 and Silo No.6 will

be fitted with double discharge chutes and pre-weigh hoppers. Minimum self-flowing

capacity of the pre-weigh hoppers will be 72 te each. Double railway lines will pass

under each of the silos such that each of the chutes of the silos will be placed over

separate railway lines.

2.5.2.2.2 Eastern CircuitEastern circuit of surface conveyors will consist a truck receiving station

with two sets of 4 x 8m x 8m x 120 te steel hoppers (3 working & 1 standby) along

with 1000 TPH vibratory feeders, two series of belt conveyors (G series) of 1600 mm

belting and 2800 TPH capacity parallel to each other, one overhead RCC bunker of

30000 te capacity and two numbers rail load out systems with 500 te capacity surge

bin and 100 te capacity weigh bin each. One series of surface conveyors will consist

of conveyors G1 & G3 whereas the other series will consist of surface conveyors G2

& G4. One of them will be working while the other will be stand by. However, in case

of peak demand or failure of other circuit both the series may be required to run

simultaneously. Conveyors G3/G4 will discharge coal onto the tripper conveyors

G5/G6 over the 30000 te bunker. However, Conveyors G1/G2 & G3/G4 will come


---------------------------------------------------------------------------------------------------------------------------------------9

after about ten years, the tripper conveyors G5/G6 will be fed by another pair of belt

conveyors G9/G10 which will reclaim coal from a nearby truck receiving station

consisting of two sets of 4 x 8m x 8m x 120 te steel hoppers (3 working & 1 standby)

along with 1000 TPH vibratory feeders. This truck receiving station will be dismantled

after installation of conveyors G1/G2 & G3/G4 and reinstalled at the tail end of G1/G2.

Coal from the bunker will be reclaimed by plough feeders of 4000 TPH capacity and

will be discharged onto the reclaim conveyors G7/G8. Conveyors G7/G8 will be of

4000 TPH nominal capacity. Two number plough feeders of 4000 TPH nominal

capacity each will be installed over each of the two reclaim conveyors G7 & G8.

Conveyors G7/G8 will discharge coal into the surge bins of the two numbers rail load

out systems. The surge bins will be fitted with weigh bins and telescopic chutes for

discharge of coal into rail wagons.

2.5.3 Coal Storage and Dispatch System2.5.3.1 Overhead RCC Bunkers

Two no. of overhead RCC bunkers of 50000 te and 30000 te capacity have

been envisaged in the western and eastern sectors of the mine respectively. The

tripper conveyors, reclaim conveyors and plough feeders of the 50000 te bunker will

of 5000 TPH capacity whereas tripper conveyors for the 30000 te bunker will be of

2800 TPH capacity and the plough feeders and the reclaim conveyors of this bunker

will be of 4000 TPH capacity. The 50000 te bunker will be attached to Silo No. 5&6

whereas the 30000 te bunker will be attached to two numbers 500 te surge bins of

two numbers rail load out systems. The bunkers will be fitted with high level and low

level indicator switches.

2.5.3.2 Rapid Loading Systems2.5.3.2.1 Western Sector

Rapid Loading Systems in the western sector will consist of two numbers of

silos i.e. Silo No.5&6 of 4000 te capacity each. The silos will be of RCC construction

and fitted with double discharge chutes and pre-weigh hoppers for weighment of coal.

The RLS will load coal into railway wagons.

The slanting surface of the silos will be lined with 10 mm thick stainless

steel liners (SS 409) and will be extended upto 3 m in vertical section. The remaining

vertical portion will be lined with epoxy based ferrosite/ ironite lining of 25 mm thick for

easy flow of coal. The silos will be designed and constructed on mass flow concept to

reduce the possibility of rat holing /arching taking place during the evacuation /loading


---------------------------------------------------------------------------------------------------------------------------------------10

process. For this, proper slopes will be provided in the slanting faces of the silos.

Provision for installation of air blasters/ air cannons will be made at suitable locations

to keep the coal agitated to avoid rat holing and arching inside the silo so that

continuous coal flow is ensured. Both the silos will be fitted with ultrasonic type high

level limit switches to stop the plough feeder below the bunker if a pre-determined

high level is reached in the silo. Low level limit switches will be provided to close the

silo discharge gates if a predetermined low level is reached i.e. approx. 600 te in the

silo. Temperature monitoring devices will also be provided at various levels in the silo

to monitor temperature of coal inside the silo and give audio-visual alarms in the

control room for necessary action. These will operate through battery in case of power

required to complete the loading of the rake ("Tons to Go"), to the PLC of the reclaim

system of the associated bunker i.e. the plough feeders and the reclaim conveyors, to

enable proper control and to coordinate the reclaim rate with the loading rate of the

load out chute. A modem with the necessary software will be provided for remote

support of the load out system and for providing system upgrades without a service

man requiring to attend the site. Lightning arrestors will also be provided on the surge

bins. All limit switches, pressure switches, temperature switches and all other

electrical components and enclosures will have a IP65 or better rating.

Two train traffic light signals, each traffic light consisting of one red and one

green light with mounting assembly will be provided. One train traffic control light

system will be mounted prior to the entrance to the load out facility. The second train

traffic control light will be mounted on the exit end of the load out structure. These

lights will provide the train driver an indication of when it is safe to begin loading. Upon

approach of train, signal will be set to red, signaling the train to stop prior to the load

out station. When the system is set and ready to load, the control room operator will

notify the train driver by switching the traffic signal to green, signaling the train driver

to spot the first wagon under the loading position. Once the train is in position and the

load out chute is positioned out over the rail wagon, the second train traffic light

control will signal the train driver to begin the loading process.

CHAPTER – 4PROPOSAL FOR ENHANCEMENT OF PRODUCTION

FROM 35.00 Mty TO 50.00 Mty4.1 NEED FOR ENHANCEMENT

As already explained based on “Road Map for Enhancement Coal Production of

CIL” the targeted production of SECL for the year 2016-17 is 149.70 Mt. Gevra OC

has been identified to produce 50.0 Mty to meet this growth in demand of SECL.

Accordingly this mining plan for enhancement of production has been prepared to

produce 50.0 Mty of coal (normative capacity) from Gevra Opencast Project. The

mining plan envisages to produce the enhanced capacity of coal from the land

already notified i.e. 4184.486 Ha, no additional land is being proposed to be acquired

in the mining plan.

As on 01.04.2016, the balance coal within the approved quarry boundary is

568.86 Mt and balance OB within the approved quarry boundary is 947.76 Mcum.

Based on this balance coal and OB the revised production programme is calculated

to estimate the required OB quantity to produce 50.0 Mty of coal. As per the revised

production programme the balance life of the project works out to about 12 years

considering normative coal production of 50.0 Mty.

4.2 FEASIBILITY FOR ENHANCEMENTThe existing Gevra OCM is producing 41.00 Mty coal since last two years i.e. in the

year 2014-15 and 2015-16, which is the limiting capacity of production as per

approved EC conditions. The mine is having potential of enhancement of production

beyond 41 Mty by deploying additional resources considering the present geo-mining

conditions. It may also be noted from the available records that in the year 2015-16

Gevra OC has dispatched 44.42 Mt of coal with the existing infrastructure available.

In the year 2015-16, NTPC Seepat has consumed coal 13.24 Mt of coal from this

mine. There is a possibility that NTPC Korba may consume coal 8.00 Mty from

Gevra OC. SILO 3 & 4 and related inpit conveyor system are in construction stage

and are likely to be commissioned by 31st Dec 2016.


---------------------------------------------------------------------------------------------------------------------------------------2

Besides this there are five nos. of sidings for dispatch of coal through rail. The

proposed dispatch modes alongwith the quantities after commissioning of silo 3 and

4 is as follows:-

4.3 BALANCE COAL AND OB REMOVALAs on 01.04.2016 balance coal is estimated about 568.86 Mt and balance OB

is estimated about 947.76 Mcum within approved mine boundary of EC.

The stripping ratio of balance coal reserve and balance OB removal works out

to 1.67 cum/t.

4.4 PRODUCTION PROGRAMME FOR 50.0 MTYCalendar programme calculated based on estimated balance coal and OB to

produce 50 Mty of coal within the mine boundary approved for EC, which is as given

below.

S.No Customers Quantity proposedto be dispatched

TOTAL 568.86 947.76 1.67


---------------------------------------------------------------------------------------------------------------------------------------3

The peak annual OB removal will be maximum 82.00 Mcum. The calendar

programme shows that the OB removal required to produce enhanced capacity of

coal, beyond Departmental capacity for OB removal as per approved PR, would

proposed to be outsourced. It is envisaged that all the OB would be dumped

internally in the individual benches of 30 m (maximum proposed dump height 90 m)

and the ultimate slope angle is proposed to be 280.

4.5 SCOPE OF WORK FOR PRODUCTION ENHANCEMENT TO 50.0 MTYThe scope of work for enhancement of production from existing acquired land

of 4184.486 Ha of land will be in line with the approved Project report of Gevra OC

Expansion (35.0-70.0Mty)

1. Additional Quantity of OB removal

The calendar programme shows that there is requirement for additional quantity

of OB removal to mine out 50.0 Mty of coal. As per approved PR of Gevra OC

Expansion (35.0-70.0Mty), removal of OB was proposed to be done by departmental

HEMM. Procurement and Deployment of departmental HEMM would take time. In

case of delay in the procurement of additional HEMMs, OB equivalent to capacity of

delayed HEMM can be outsourced till the procurement of these HEMMs.

2. Additional Quantity of Coal extraction

As per approved PR of Gevra OCM (35-70Mty), extraction of coal to be done by

Surface Miner on outsourcing basis. The same would be continued for this mining

plan also.

3. Infrastructures for Transportation and Dispatch of coal.

Development of Infrastructures for transportation and dispatch of coal will be as

per the Project report of Gevra OC Expansion (35.0-70.0Mty)

4. Other Developmental activities and manpower requirement.

As per the Project report of Gevra OC Expansion (35.0-70.0Mty).

5. Mine closure activities

As per the Project report of Gevra OC Expansion (35.0-70.0Mty).


---------------------------------------------------------------------------------------------------------------------------------------4

4.6 FUTURE PLANNINGThe approved PR has been planned to produce 70.0Mty of coal. The strike

length of 9.5 km has been planned in the approved PR. The mining plan has been

prepared as stop gap arrangement to produce 50.0 Mty of production to cater the

increased production of SECL. All efforts would be made to acquire the additional

land and obtain EC as soon as possible so that the mine produces 70Mty as

projected in the PR, preferably within 3 years time. The time line for major activities

to implement approved 70 Mty PR is as indicated in following paras.

The schedule for acquisition of land is as follows:

Completion of section 11 for land acquisition as per CBA Act of remaining

land -2017-18

Forestry clearance of forest land within the approved PR of Gevra OC

Expansion (35.0-70.0Mty)-2018-19.

All the major infrastructures as per the approved PR for Gevra OC Expansion (35.0-

70.0Mty) are to be constructed within the approved EC land of 4184.486Ha. The

schedule for the infrastructure development would be as follows:

Construction of silo nos. 5&6 and inpit conveyors/surface conveyors:-2018-19

Construction of load out system and inpit conveyors/surface conveyors-2018-19

In addition to this all out efforts will be made for commencement of EAST-WEST Rail

corridor by 2018-19.

After completion of major activities and forestry clearance application will be

processed for EC of 87.5Mty later on.

4.7 CONCLUSIONThis mining plan would facilitate Gevra OCM to gradually reach to its projected

approved target of 70 Mty from the existing approved EC capacity of 41 Mty. It is

proposed that production of 50 Mty would be reached by gainful utilisation of the

existing infrastructure however, as the infrastructure to produce & handle 70 Mty is

available in due course of time, the mine would produce its projected approved


---------------------------------------------------------------------------------------------------------------------------------------5

target of 70 Mty. It is envisaged that the required infrastructure to produce & handle

70 Mty would be constructed within 3 years time frame.

Considering the feasibility to produce and dispatch 50 Mty by utilising existing

infrastructure within existing acquired land, the mining plan to Gevra Expn. OCP may

be considered for approval by competent authority.

CHAPTER- 5

ENVIRONMENT MANAGEMENT

5.1 Existing Environment Quality:

Gevra OCP is an operating mine under Gevra Area, SECL and comprises mostly

of agricultural land. Presently, 41 Mty of coal is being extracted from 4184.486 Ha of

land. In order to enhance coal production of Gevra OC, it was planned to acquire

additional land. But this additional land to be acquired contains forest right at the

boundary of expansion. Obtaining forest clearance for this forest land would take

considerable amount of time, so it has been proposed by competent authority that coal

production be enhanced in the present acquired land (4184.486 Ha.). Availability of

sufficient coal reserves in the present land in use makes this proposal feasible for

enhancement of coal production from 41 Mty to 50 Mty.

Environmental base line data for Gevra OC Expansion was generated in the year

of 2008 and subsequently monitoring data is carried out at different locations in core &

buffer zones. These data have been used in the preparation of this chapter. These data

will enable in obtaining a comprehensive idea of environmental quality in and around the

proposed project area in respect to air quality, water quality, noise level, flora fauna,

socio economic data etc. Detail existing environmental base line data is being generated

for the season April-June 2016. This data will be incorporated in the final EIA/EMP

report, which will be submitted to MoEF & CC.

5.1.1 Ambient Air quality in core and buffer zone:

To assess the ambient air quality, eight monitoring stations were fixed on the basis

of physiography of the area, meteorological parameters like predominant wind direction,

wind speed etc. The details of air quality monitoring locations are given below in Table

5.1.4 Flora and FaunaForest, Flora & Fauna

Baseline data for Flora & Fauna for Gevra OC have been generated in June-

August 2015 and the same has been taken as a reference for this section. The study

area for the Flora & Fauna covers 10 KM radius from periphery of the Core Zone of the

Gevra OCP in the Gevra area of South Eastern Coalfield Limited (SECL). The flora and

fauna report of Gevra OC generated reveals the following summarized list of flora and

fauna normally found in that forest.

Conservation and Management of Biological diversity:There are no reserve forests either in the core area (MLA) or in the buffer area

(Area enclosed within 10 Km radius from periphery of core zone of Gevra OCO). But

there are a few Protected Sal forests are found in the buffer zone of the mine lease

area (MLA). The reserve forests were dominated by Sal (Shorearobusta) with Butea

monospermaand Madhucalongifoliaas the codominant species. They are open with tree

density ranging from a low of 36 to a high of 340 trees per hectare. A few areas were

colonized by Bamboo (Dendrocalamusstrictus). Lantana camaraalong with the coppiced

shoots of Butea monospermawas the most widely scattered shrubs in the gaps within

the reserve forests. The protected Sal plantations are harvested periodically for timber.

Conservation of Flora & Fauna:Open cast Mining iscapable of causing extensive

damage to the flora and the associated fauna of the mining site. But the impacts can be

reversed and the flora and fauna can be rehabilitated and restored through location and

site specific eco-restoration process. The floral conservation plan is mainly focused on

artificial regeneration of a good tree cover through afforestation of the overburden

dumps, back filled sites and the abandoned vacant areas. Water available in the mine

pits could be diverted for sapling nursery and plantations. The restored areas will be

protected from biotic pressure by fencing. It is evident from the baseline data of the flora

and fauna of the core area as well as from the eye witness accounts that no Rare or

endangered or endemic or threatened (REET) species or species included in Schedule I

of the Wildlife Protection Act of 1972 were spotted in the Mine lease area (MLA) during

the past 10 years by the local observers. The presence of such species in the buffer

area is also unlikely.

However, the buffer zone is covered by a good diversity of plant species that

comprised of herbs, shrubs and tree species. The small plants such as herbs, medicinal

herbs and commonly available weeds were found to be good in number and these

plants were having the potential of rapid regeneration and spread. Due to self-

regenerative capacity of these plants, the propagation strategy is not required. Except

for a few plant species, all the plant species found in this region were found to be

commonly available flora of all the regions. To improve the vegetation cover, it is

suggested that the saplings of diverse tree species such as Acacia catechu,

Anogeissuslatifolia, Butea monosperma, Diospyrosmelanoxylon, Madhucalongifolia,

Lagerstroemia parviflora, Lanneacoromandelica, Shorearobusta, Terminalia bellirica,

Boswelliaserrata, Dendrocalamusstrictus, Cassia siamea, Eucalyptus globules, Acacia

auriculiformis, Albizialebbeck, Azadirachtaindica, Dalbergiasisoo, Gmelinaarborea,

Phyllanthusemblica, Pongamiapinnataand Tectonagrandiscould be planted to fill the

gaps at a regular intervals. The natural forests should be protected as envisaged by the

forest conservation act.The flora & fauna identified in the study area is summarized below.

5.3 Environnent Management5.3.1Air Quality Management

Following air pollution control measures are will be practiced within the mining area

and at coal handling plants and railway siding.

1. Water spraying will be done regularly on approach roads within the mining area to

minimise the dust generation.

2. Mist sprinkling arrangement will be provided at the transfer point of coal.

3. Intensive plantation of adequate width all along the haul road and other road will be

raised to minimise transport generated pollutants.

4. Crusher house of CHP will be provided with dust extraction arrangements.

5. Minimising the transport of coal from the crusher house to silo loading system, belt

conveyor has been provided.

6. Coal transportation to railway siding will be done in covered trucks.

7. Exposed overburden dumps will be covered through an appropriate plantation

8. The drills will be equipped with dust arresting devices or wet drilling arrangement.

9. Optimum blast-hole geometry will be followed to reduce the dust during blasting.

10. Regular monitoring of ambient air quality of project area.

5.3.2 Water Quality Management

Management of surface water drainage: -

Garland drainage will be made around the periphery of the quarry. These drains

will be connected to Laxmannala, flowing in the north side of the mine. In the workings,

heavy duty pumps will be deployed in rainy season which after passing through settling

ponds will throw the accumulated water from the working face into these garland

drains.

Mine Water Discharge

The collected water at the floor of mine sump will be pumped to the settling tank

where suspended solids will get settled. The clear water after sedimentation & treatment

will be reused for water sprinkling, plantation & agriculture purpose, ground water

recharge & for use by the local villagers etc. Workshop effluents will be discharged

through Oil and Grease trap and sedimentation tank.


14

Domestic Effluent Treatment: -DETP has been provided for treatment of domestic effluent from the colony.

Water Conservation: -

The waste water recycling after due treatment will enable conservation of water.

Storage of conserved water in mine pits would be given due emphasis to provide water

round the year and the quality of water would be maintained. The balance left mined out

area of 659.25. Ha. would be treated as water body after mine closure. This would serve

as a considerable source of water for the use of local population.

Control measures adopted against impact on ground water regime:-

i) The impact will be limited to a smaller distance and for a temporary period. The

effected habitation will be provided with suitable drinking water supply by sinking

hand pumps in the habitat.

ii) The entire mine industrial water demand, would be met from the treated mine

discharge. The wastage of water will be minimized.

iii) The surplus treated mine water will be discharge into the agricultural fields.

Thereby, the mine water will behave as constant source of recharge and

improves the water levels in the mine area. This will also become a resource for

the local public and increase agriculture output.

iv) So also, after cessation of mining, part of the quarry area will be reclaimed with

highly permeable OB material. The final void would be converted into a water

reservoir. Thus, in post-mining, the recharge and source potential in core zone

will be much higher than the existing.

v) With the increase in secondary porosity, a significant improvement in the rainfall

infiltration rate, close to the mine area can be anticipated.

5.3.3 Noise ManagementThe present noise levels are below the prescribed limits. If the impulsive noise

levels increase due to mining operation, suitable measures will be adopted to maintain

the noise level within permissible limits at working zone. The following measures are

adopted and will be continued:


15

1. Planting of rows of trees with thick foliage along roads and other noise

generating centers to act as acoustic barriers.

2. Isolating/enclosing the noisy machines/sources by using resilient

mounting/altering structures.

3. Routine maintenance schedules for HEMM and other machineries to eliminate

noise as far as possible.

4. Balanced and properly aligned conditioning of machines to reduce vibration.

5. Provision of ear muffs/ear plugs to workers subjected to noise level above

recommended limits.

6. Controlled blasting.

7. Regular monitoring of noise level of project area.

5.3.4 Flora and Fauna Management

The location of Gevra OC Block does not have any importance as a holiday

resort. The surface to be disturbed by open cast mining operation does contain any rare

variety of flora or fauna. As such, consequent to the opencast mining operation,

deterioration in quality of life or loss of amenity is not envisaged. Conservation plans of

schedule I & II animals, if any, will be prepared and implemented.

Compensatory afforestation and Strengthening of safety zone will be done. SECL

will develop this integrated area, as habitat for the fauna. The following steps will be

taken for development of habitat:

Reclamation of mine void:

In the core zone, after the cessation of mining activity a void will be created. This

void will be used as a water body. This will be graded to a gentle slope so that it acts as

a safe approach / access to the water body for the faunal species. Through Community

development work in villages existing in the buffer zone existing water sources

particularly the village tanks will be improved to provide drinking water to the local

community so that biotic pressure on water resources present in the forest areas and

used by fauna is gradually reduced.


16

Control of forest fire, fire in coal seam and coal stock.

Fire can destroy the entire habitats (micro and macro) and its life supporting

potential in a forest area.Fire does not spare fauna also.SECL will implement the

existing DGMS stipulated fire protection norms on coal seams and coal stock. This will

ensure that a congenial atmosphere is created and fire does not affect the fauna and

flora as well.

5.3.5 Land Resource Management

The existing land use and post-mining land use are shown below:

Existing Land Use:

It is estimated that 4184.486 Ha. of land will be required for Gevra Opencast Project (50

Mty) including land for quarry, external dumps, industrial and residential complex, road

diversion, safety zone and rehabilitation colonies.

The break-up of land use is given below and shown in Table- 5.14.

Post Mining Land Use:

There would be a creation of about 2438.672 Ha. of forest by way of compensatory

afforestation , reclamation of dumps etc. against a degradation of 1038.63 Ha. of forest

by the mining activity. This is a positive impact. Details of plantation nos. as well as

Monitoring Schedule

Environmental monitoring will be carried out following the monitoring schedule for

Air, Water, and Noise levels as per Standards of MOEF (Vide GSR 742 (E) dated

25.9.2000)

Plantation Monitoring

The project authority at field level will continuously monitor the growth and

survival/mortality rates of the plantations till the end of 3 years. Once trees attain

desired growth, no further monitoring will be required.

Action Plan for Land Reclamation and Plantation

A total of 1661850 no. of plants is estimated to be planted in the reclamation of

internal dumps. An area of 659.25Ha would be left as final void/water body after mine

closure. The dump surface would be maintained flat and top soil would be spread over it

as a part of final reclamation.Year wise programme of OB removal, dumping, &
