SALIENT FEATURES Of PB NORTH WEST QUARRY

INTRODUCTION

The Pakri Barwadih North West Quarry is a part of Pakri Barwadih Coal Block of 46.26

sq. km) is located in North Karanpura Coalfields in Hazaribagh district of Jharkhand

state. It is located at a distance of 40Km from Hazaribagh via Barkagaon. The block

has been allocated to NTPC Ltd., for captive mining for supply of coal to their super

thermal power stations

The Block Area of Pakri Barwadih North West Coal Block is 4.85 Sq Km. The north

western part of the block exhibits undulating topography with general slope towards

south. Due to presence of numerous ravines in the eastern half of the block, the

topography is highly rugged, rendering the area unapproachable. In general the

elevation of ground varies from 430m to 460m above mean sea level.

The drainage of the PB block is controlled by Sunrah river, which finally joins to

Badmahi river, which is one of the major tributary of Damodar river flowing in south

central part of coalfield. Three major nallahs flowing north to south are Khora,

Dumuhani and Hardara (Pakawa). None of the nalas/tributaries were planned for

diversion except straightening of Khora Nala – B at NW part of the block. During

mining, adequate clearance from high bank of nala are left on the active pit side, to

prevent seepage/flooding of water to mine. Embankments are also planned to prevent

inrush of water during rainy season or otherwise.

Mining Plan and Mine Closure Plan of the Coal block has been approved by Ministry

of Coal for a targeted capacity of 3 MTPA with a mine life of 52 Years including 3 years

of Construction period.

GEOLOGY & MINING

Pakri Barwadih North West Quarry is located in the North Karanpura Coalfields. The

general strike of the formation in the block is almost east-west. The local swing in the

Page 2 of 4

strike at places is due to rolling dip. The strata are dipping at 10° to 12° southerly. The

block is traversed by 8 numbers of faults. Among these, 3 faults are varying from 0 m

to 50 m. Detailed exploration has established the presence of 10 Nos. of seams, 5

each coal bearing horizons belonging to Barakar formations and Karharbari formation

respectively.

Detailed exploration has established the presence of 10 Nos. ofseams, 5 each coal

bearing horizons belonging to Barakar formations and Karharbari formation

respectively. In ascending order these are seam K-1,K-2,K-3,K-4,K-5 in Kharharbari

Formation and Local(L),I,II,IV& V In Barakar Formation. Seam I splits into 3 sections

viz. I Top, I Middle & I Bottom at places. Seam I Bottom and I Middle combined and

form single seam namely I Bottom + Middle. Similarly Seam II also splits into 3 sections

viz. II Top, II Middle and II Bottom. Seam II Top and II Middle coalesce to form single

seam as II Top + II Middle in eastern part. In Pakri Barwadih North West (Sector-A)

Coal Block Seam V & IV occur as a combined seam.

Total estimated mineable reserves within the block is 138.96 Million Tonnes and

corresponding total overburden is estimated as 438.24 million cubic meters with a

Striping Ratio of 3.15m3/t .The life of Mine as per Approved Mining Plan & Mine

Closure Plan is 52 years including 3 years of construction period, however, the

contract period is for 25 year of coal production with a mineable reserve of 69.50 MT

and Over Burden of 217.12 Mm3 with a Stripping Ratio of 3.12 m3/t.
