SALIENT TECHNICAL FEATURES
INTRODUCTION
Chatti Bariatu Block has been allocated to NTPC by MoC vide Allotment Agreement
dated 30.03.2015. It is located in the northern part of the North Karanpura Coalfield
and lies in Hazaribagh district of Jharkhand. This block is contiguous to Pachra
block in the west, Dumri block in the north, Kerendari ’A’ in the east owned by
NTPC and Chatti Bariatu South block located in the south (presently clubbed with
Chatti Bariatu Coal Block as per Allotment Agreement).
The block is about 50 km. from the headquarters of Hazaribagh district and is
connected by an all weather metalled road going from Hazaribagh to Tandwa and
the nearest rail head is Ray Railway Station at a distance of about 38 Km from the
block on Barkakana-Dehri-on-sone loop line.
The Chatti Bariatu block shows more or less flat terrain with gentle undulations. The
drainage of the block is controlled by two prominent nalas, of which one flows west
to east in northern part and locally called as Baledeori nala and other nala flows
south joins Baledeori nala further downstream.
The Mining Plan and Mine Closure Plan of Chatti Bariatu Block is already approved
by Ministry of Coal for a targeted capacity of 7 MTPA. Environment clearance and
Forest clearance has been granted by MoEF.
GEOLOGY
Total area of the allotted coal block is 646.23 Ha. The block is faulted with 3 faults.
The strike of the strata is roughly E-W with southerly dip of 3
o
to 15
o
. The dip in
western part of the block is flat having generally 4
o
to 6
o
. The dip in central and
eastern part of the property has steepened to generally 7
o
to 15
o.
There are mainly five coal seams in Barakar formation, viz seams-I, II, III, IV &
Local. The generalized thickness range of most potential coal seams of the block
are Seam-I Bottom (3m-5m), Seam-I Top &Middle (8m to 11m), Seam-II Bottom (5m
to 7m), Seam-II Top (1m to 2m) , Seam-III Bottom (1.0m to 1.5m), Seam-III Top (1m
to 2m), Local Seam ( 1m to 1.5m), Seam-IV (5m to 7m) & Seam-IVA ( 1.0 m to 1.5
m). The remaining coal seams are thin having thickness generally less than 1m.
The total Mineable reserve in the block is 151.80 Million tones. The total
corresponding overburden/ interburden is estimated as 259.49 million cubic meters.
The average stripping ratio is 1.71.
