PRE-FEASIBILITY REPORT FOR

KULDA EXPANSION OPEN CAST PROJECT (CAPACITY 15.0 MTY)

1. INTRODUCTION

Ib Valley Coalfield located in the districts of Jharsuguda, Sambalpur and

Sundergarh of Odisha is having latitudes 21031’ to 22014’N and longitudes

83032’ to 84010’E. The coalfield is named after the river Ib, a tributary of river

Mahanadi. Coal reserves of this coalfield are about 24.83 billion tonnes (as on

1.4.2015) of which about 15.10 billion tonnes lie within a depth range of 300m.

Quality of coal varies from grade C to G (largely F), suitable for power

generation.

Coal demand from Ib-valley coalfield has increased many fold due to its

strategic location with Howrah-Mumbai railway line passing through the

coalfield. Coal of this coalfield is suitable for thermal power plants.

Many pit head power plants and other coal based plants have come up due to

easy availability of coal and water. The southern, western & central India power

stations have to depend on Ib valley coalfield for their growth. The Howrah-

Mumbai line passes through the coalfield. So coal can move from this coalfield

to western India power houses via rail route. Coal to Tamil Nadu Electricity

Board is also supplied via rail-cum-sea route through Vishakhapatnam and

Haldia ports. Coal can easily move from this coalfield to Eastern India and

Northern India as well. Necessary infrastructure facilities like rail etc. are being

developed/ augmented in the region.

The proximity of Ib-valley coalfield to Hirakud reservoir has generated a lot of

opportunities for setting-up super thermal power stations in the vicinity of the

coalfield.

Gopalpur sector of Ib-valley coalfield forms the north western part of Ib River

coalfield which is a greenfield area with huge mining potential. Detailed

exploration was undertaken by CMPDI to assess the quarriable potentiality of

coal seams with primary view of opening up of new mining projects to the

CMPDI


extent possible. This sector has high potential for opencast mining operations.

Kulda Opencast Project is located in this sector.

Rail link from Jharsuguda to Barpali i.e. adjacent to Kulda OCP, is in very

advance stage of completion & will soon start it’s operation.

2. STATUS OF KULDA OCP

The Advance Action Proposal (AAP) of the project was sanctioned by Govt. in

October 1995 for a capital investment of Rs.8.624 crores.

PROJECT REPORT

Project Report (PR) was approved by MCL Board in March 1995 and

subsequently by CIL Board in May 1995. The PR could not be processed

further due to lack of forestry clearance and EMP clearance. Later project

report was revised with different size of HEMM. This proposal was approved by

MCL Board on 24.11.2001 and by CIL Board on 6.3.2002. Finally the proposal

of Kulda OCP (UCE-August, 2004 cost base) was sanctioned by CCEA in

January,2005 in coal and OB outsourcing variant .

MINING PLAN

Mining Plan for Kulda OCP (10.0 Mty) was approved by MoC, Govt. of India

vide letter no: 34012/(4)/2011-CPAM dated 1st July 2011.

STATUS OF EMP

Env. Clearance for Kulda OCP (10.00 Mty) was received vide letter

No.J/11015/10/95-IA.II(M) dated 24.12.2002 (Annexure-I).Total mine lease area

was 929.60 Ha inclusive of 279.20 Ha of forest land. But environmental

clearance was accorded for 878.29 Ha inclusive of 227.89 Ha of forestland for

which diversion proposal (forestry clearance)has been obtained by the project

for first phase of mining for initial 20 years.

STATUS OF FORESTRY CLEARANCE

Stage-I forestry clearance was received for land required for a period of 20

years from MOEF in two stages for 50.72 Ha on 25.07.2001 and 177.17 Ha on

CMPDI


22.01.2002 respectively. Stage-II clearance was obtained on 08.08.2007 for

227.89 Ha of land for 20 years of mine workings. (Annexure- IV)

Mining Plan/ Mine Closure Plan for Kulda Expansion OC Project

(Revision-I), Expansion from 10.0 to 15.0 Mty, has been prepared within

notified area of MCL for which stage-II forest clearance has been obtained

(634.205 Ha excluding the area under Lalma Forest). Although additional non

forest land is available to be included in the present lease area but presence of

scattered forest land does not permit these areas to be included in phase-I

mining operation. Remaining part of the block including Lalma forest will be

taken up for mining later after getting forestry clearance as phase-II. Mining

Plan/ Mine Closure Plan for Kulda Expansion OC Project (Revision-I),

Expansion from 10.0 to 15.0 Mty, has been approved by Ministry of Coal vide

Letter No. 34012/(04)/2011-CPAM dated 26-12-2016.(Annexure II).

3. NEED / JUSTIFICATION FOR THE PROJECT

To meet the increasing demand of power in the country, more and more super

thermal power stations are being planned in western, northern and eastern

India, majority of which are coal based and may be linked from Ib-valley

coalfield. Power Houses of Punjab State Electricity Board, Haryana State

Electricity Board have also been linked to MCL and will be supplied coal from

this coalfield. The New Power houses of TNEB, KPCL, WBPDCL, CESC and

DVC are also linked to the coalfield.

The consumers of MCL are linked to the company and not to any specific

coalfield. The actual supply from any coalfield of MCL will depend upon the

production and transport logistics. Under the above circumstances coalfield

wise demand has been assessed. Projected coal demand on MCL from Ib-

valley coalfield is as below:

Projected coal demand on MCL from Ib-valley coalfield (Fig. in Mt)

Sl. No

Particulars 2016-17 2021-22 2026-27

valley coalfield 70.62 97.93 120.56

3 Coal Availability 46.39 69.61 70.40 Gap (-)24.23 (-)28.32 (-)50.16

CMPDI


From the above table, it can be seen that all the operative mines in the coalfield

along with the new projects already formulated will not be able to meet the

future demand over the area. Demand during XII Plan period is likely to

increase with fresh linkages to various power houses. Further expansion of

these projects &/or opening of new mines may be required to meet the

projected demand.

In the light of above, expansion of Kulda OCP from 10.0 to 15.0 Mty is justified.

It is proposed that the coal produced from the proposed project will be linked to

various Thermal Power Stations for power generation, both within the state and

outside the state.

4. LOCATION AND COMMUNICATION (PLATE IA & IB)

5. TOPOGRAPHY, DRAINAGE AND CLIMATE (PLATE-V)

The topography of the block is rugged with steep rise and fall. The central

and south eastern part lie at a comparatively higher elevation being dotted with

hillocks.

The minimum and maximum elevations of the area are 254m and 320m

respectively above the mean sea level.

The ground slopes generally towards west and north and ground water is

collected by Chattajhor nallah being fed by streamlets, which in turn feeds to

river Basundhara.

River Basundhara flows along northwest and northern boundary of the block.

The climate is sub-tropical. Temperature varies from 9.3oC (winter season) to

44.1oC (in pre-monsoon season).

The average annual rainfall is 1413 mm as measured at IMD Jharsuguda for

the last 24 years.

6. GEOLOGY

"Geological Report on Kulda Block, Ib River Coalfield" was prepared by CMPDI

in Feb.'1994. A total of 130 boreholes, have been drilled with a total meterage

of 14858.35m covering an area of 5.84 sq.km. Coal bearing area is 5.30 sq.km.

The borehole density is about 22.3 boreholes/sq.km. The geological succession of Ib Valley and Stratigraphic succession of Kulda

Block is given below.

CMPDI


Structure

Strike of the strata is roughly NW-SE. The dip is generally 7o towards

southwest. Dip is slightly higher in southern part and near faults compared to

rest of the area.

Existence of 3 no faults has been interpreted on the basis of borehole data with

varying throw from 0 to 15m .

Deposit Characteristics

Three coal seams namely Ib seam, Rampur seam and Lajkura seam occur in

this area. These three coal seams altogether occur in 12 split sections, leaving

mergers & sub-splits. Ib seam is the bottom most coal seam.

Ib seam occurs in three sections. Ib bottom seam, which is the lowest coal

section, is not workable in the northern part of the block. Ib middle section

which overlies Ib bottom section is also not workable in the northern part.

These two sections are combined over major part of the block. Ib top section is

not workable over major part of the block and is not considered in quarriable

reserves.

Rampur seam occurs in five sections. Rampur-I seam which overlies Ib middle

section is not workable in the northern, southern & south eastern parts. It is

combined with overlying Rampur-II seam over a long narrow strip in the

western half of the block. The workable section of Rampur-I occurs at a

minimum depth of about 34m in the region of borehole CMHG-118 while

Rampur-II seam occurs in the entire block as workable coal section. Rampur-III

bottom is not workable in the northern half of the block whereas other split

sections overlying Rampur-III bottom are workable in the area of occurrence.

Lajkura horizon occurs in four sections and all coal sections are workable in the

area of occurrence. Out of these four sections Lajkura-II seam is the thickest

with a maximum thickness (including all bands) of 34.07m.

The parting between Ib middle seam and Rampur horizon varies from 3.79 to

13.62m. The parting is thicker where Rampur I is not workable. The parting

between Rampur horizon and Lajkura horizon is thickest with thickness ranging

from 31m to 47m. Except these two partings other intervening partings between

split sections are generally thin.

CMPDI


In all 438.90 Mt coal has been estimated within the block, out of which 26.06 Mt

is locked up within 60m barrier zone and 412.84Mt lies beyond barrier zone.

Succession of coal seams

The grade of coal varies between C to G.

7. MINE BOUNDARY

Kulda geological block contains about 438.90 Mt of net geological reserves

(vertical) with an overall vertical stripping ratio of 0.86 cum/t. The maximum

depth upto floor of Ib bottom seam is about 238m. The entire reserves are

quarriable.

The geological block is bounded by Basundhara river, incrop of Rampur seam

on the north/north eastern side and Chattajhor nallah on the western side.

Chattajhor nallah has a meandering course giving rise to irregular block

boundary. Therefore it is proposed to straighten nallah course at two places

near boreholes CMHG-227 and CMHG-216. Surface boundary is arrived after

leaving a surface barrier against nallah and the river.

In this revised Mining Plan for Kulda OCP (Expansion from 10.0 to 15.0 Mty)

mining has been proposed to be done in two phases.

PHASE-I

Phase-I mining operation will be taken up initially, here surface boundary has

been restricted within notified lease area for which forest clearance has been

obtained by the project authority. In this phase certain portion of the block

towards south and south-east including area under Lalma Forest are excluded

from the mine boundary as which was present in original mining plan. This

revised mining plan has been detailed for phase-I mining operation, which is a

part of original approved mining plan.

PHASE-II

Phase-II mining operation will be taken up in later years after completion of

phase-I. remaining part of the block will be worked in phase-II after obtaining

forest clearance for the this area. Details of this phase-II will be included in a

separate mining plan at later date.

As explained earlier Ib bottom, Ib middle and Rampur-I seams are not workable

on northern side. Even after, Ib bottom seam attains workable thickness of 1m,

incremental thickness ratio is adverse due to inconsistent development of Ib

middle seam and Rampur-I seam. Hence, it is proposed to adopt Rampur-II

floor as the mine floor upto 185m/190m floor contour of Rampur-II seam and

thereafter deepen the mine floor to floor of Ib bottom seam floor.

Based on the reasons explained in previous paragraphs, mine boundaries

adopted in Phase-I are summarised below:

North : Floor boundary is arrived after leaving surface barrier of

about 60m against river. East : Roof incrop of Rampur-II seam. South : boundary of notified area by project authority for which

stage-II Forest Clearance is available (excluding Lalma RF in the south-west for which forest clearance is available).

CMPDI


West : Floor boundary is marked after leaving a surface barrier of about 60m against Chattajhor nallah and its straightened part and boundary of Lalma RF.

Mine boundaries adopted as per original mining plan will remain same for both

phase of mining operations and these are summarized below.

North : Floor boundary is arrived after leaving surface barrier of about 60m against river. Quarry slope is about 370.

East : Roof incrop of Rampur-II seam. South : Geological boundary is adopted as surface boundary. West : Floor boundary is marked after leaving a surface barrier of

about 60m against Chattajhor nullah and its straightened part.

9. MINING TECHNOLOGY

The prevalent mining and geological conditions comprise of the followings:

i) Presence of 3 nos. thick coal horizons namely, (a) Ib (8 m), (b) Rampur (45 m), (c) Lajkura (50 m).

ii) The above coal horizons contain multiple coal sections with intervening

partings. Thickest coal seams/sections are Rampur (IV+V) (25 m) and Lajkura II (31 m).

iii) Gradient of the seams (5o to 8o). iv) Low average stripping ratio of 0.87 cu.m per tonne. Considering the above prevalent mining and geological conditions, shovel

dumper mining system in overburden and Surface Miner with Front End loader

and Rear dumper for coal extraction has been suggested.

The external overburden and the thick parting between Rampur and Lajkura

seam horizons are proposed to be worked by horizontal slices, whereas all the

coal seam sections and the intervening partings in Ib, Rampur and Lajkura

seams are envisaged to be worked by inclined slices considering the moderate

gradient.

At present coal winning is done by surface miner and OB removal is being

done by shovel dumper combination.

Project report of Kulda OCP (10 Mty) was approved for both coal & OB

outsourcing variant. Kulda OCP (15 Mty; 5 Mty incremental) has been

approved for incremental coal & incremental OB both by outsourcing. In

sanctioned outsourcing variant equipment requirement and its phasing will

depend on the outsourcing agency. But the optimum choice of equipment as

per departmental variant has also been assessed; total requirement and its

phasing have been calculated based on the calendar plan of operations,

revised productivity of HEMM and possible physical deployment of equipment

in various horizons.

Requirement of HEMM (in case the mine is operated departmentally) is given

below.

14. PUMPING AND DRAINAGE

The pumping system has been designed to dewater the inflow of water due to

precipitation falling within the active pit limit during the monsoon season to

enable the mining activity to continue round the year.

The existing pumps as proposed in the approved project of 10 Mty are sufficient

for expansion project also.

15. COAL WINNING AND OB REMOVAL

At present coal winning is done by surface miner and OB removal is being

done by shovel dumper combination.

Because of same geomining conditions, shovel dumper mining system is

proposed for partings/top OB and surface miner is proposed for coal and in-

seam bands in proposed expansion project also.

16. MANPOWER

The existing manpower of the project is 816. The additional manpower for

expansion project has been estimated as 91.

17. POWER SUPPLY

Main power supply is from 220KV Main sub-station at Garjanbahal which was

charged in October 2012. Power is transmitted to 2.5 MVA, 33/6.6 KV

substation near existing mine.

Power at 6.6 kV for CHP is proposed to be received from the existing feeders of

2X5 MVA, 33/6.6 kV project substation at Kulda OCP through double circuit

overhead line. One of the two incoming feeders will normally be kept as stand

bye. It is proposed to establish one number of 6.6 kV substation in a suitable

location near CHP to cater to the power requirement for different equipment of

CHP.

18. COAL HANDLING, WASHING & DISPATCH ARRANGEMENT

The proposed Kulda Expansion OC Project is planned to handle the total

production of 15.0 Mty. Presently, the CHP is having 2 nos. feeder breakers of

200 to 300 tph (approx.) capacity and dispatch the crushed as well as blast free

coal through the existing truck loading hoppers to nearby siding.

CMPDI


For proposed system out of 15 Mty, blast free raw coal of 10 Mty will feed to

proposed Basundhara Washery and rest coal is being dispatched to Kanika

siding to a distance of about 30 km with local sale also till the railway siding at

Sardega/Barpalli comes up.

The coal handling arrangement feeding the raw coal to 10 Mty Basundhara

washery and one silo to dispatch washed coal into wagons shall have the

following provisions:

Four numbers of reclaim feeders located at a suitable position near the

mine access trench to receive the blast free raw coal to handle 10 Mty

capacity.

The entire 10 Mty raw coal reclaimed by the reclaim feeders and

transported up to the proposed Basundhara washery (10 Mty) by sets of

belt conveyor C1&C1A, C2&C2A and C3&C3A and feed at a two points

of Washery complex at a height of 10-15 mtr.

The balance 5 Mty of conventional as well as blast free coal collected

and transported up to the existing wharfwall siding at Kanika using

existing Feeder breaker circuits.

In future, if the capacity of washery will be enhanced, modification of raw coal

feeding will be done accordingly to handle 15 Mty raw coal.

Washed Coal Transportation through Silo

The total washed coal from the Basundhara washery (10 Mty) shall be

transported upto Silo by conveyors.

The washed coal from Basundhara washery (10 Mty), shall be loaded into

wagons by Rapid loading system (i.e. SILO located on MGR loop near Barpali

yard) at the capacity of 5500 tph.

19. WORKSHOP AND STORE

As per approved Project Report of existing Kulda OCP, there is provision of a

HEMM workshop. The existing workshop and store shall cater the need for the

expansion project also.

25. RAIN WATER HARVESTING

Rain water is naturally pure water except where it becomes acidic due to

industrial pollution. The rapid exploitation of ground water as well as surface

water due to the industrial developmental projects, increase in population

CMPDI


resulted in acute scarcity of fresh water availability. It has become necessary to

conserve this valuable natural resource for sustainable development.

Conservation of this valuable natural resource can be done by collecting this

rain water scientifically and utilizing it either for drinking purposes or ground

water recharging purposes.

Scientifically & technically designed system which helps us to collect and utilize

the rain water effectively through various steps and collectively termed as “Rain

Water Harvesting”.

The various steps/methods are roof top catchments, check dams, percolation

pond, storage tanks, etc.
