SALIENT FEATURES
INTRODUCTION
The Pakri Barwadih Coal Block is located in North Karanpura Coalfields in Hazaribagh district of Jharkhand state. The block has been allotted to National Thermal Power Corporation, now NTPC Ltd (NTPC) for captive mining for supply of coal to their super thermal power stations by Ministry of coal, Government of India vide letter no.
The Hazaribagh – Khelari – Ranchi State highway passes through the eastern part of the block touching Barkagaon and Tandwa Villages. The nearest township is Hazaribagh located at a distance of around 25 kms from Barkagaon in the southern part of the block. The nearest rail stations are Ranchi Road and Chitarpur on the Gomoh Barkakana –
Ranchi which is the state capital of Jharkhand is around
There are a number of seasonal streams/ nallahs traversing the block and the prominent ones are Dumuhan, Hardara, Khora etc. flowing roughly north to south and carry huge load during rainy seasons. None of them are perennial in nature. They discharge their load into the Badmahi river flowing further south of the block and is one of the important tributaries of the mighty Damodar river flowing west to east in southern part of the North Karanpura Coalfield.
GEOLOGY & MINING
The Pakri Barwadih Coal Block covers an area of 46.95 sq km (approx), which includes Pakri Barwadih ‘A’, area for mining in eastern and western quarry, area for infrastructure, dump, conveyor corridor etc.
The block comprises of Talcher, Karharbari, Barakar, Barren Measures and Raniganj formations belonging to Damudas, a Sub Group of Lower Gondwana. There are a few small outliers of Barakar/ Kaharbari/ Talchir Formations occurring over the
Structurally the coalfield is a major broad syncline with its axis trending east to west and plunging towards east. The
The block is generally traversed by
The Barakar formation contains five persistent coal seams numbered seam I to V in ascending order. Out of these, seams I & II have spitted into 3 sections, whereas seam III, IV and V spitted in two sections each. The split sections are designated as top, middle & bottom. The split sections of the seams merge to form composite seams designated for example as IIC for II composite, II TM for II Top & Middle combined and MB for Middle and Bottom combined. The coal seams have been intersected by 19 nos of faults of variable throw ranging up to 170 m.
The Karharbari formations underlies the Barakar formation and contain 5 thin
Total net geological coal reserves (as per Geological Report) are 1436 Million tones (Mt) out of which 707 Mt are up to 300 m depth and are generally considered quarriable and hence have been proposed for open cast mining. Out of 707 Mt, 594 Mt is proved reserves and 113 Mt are indicated reserves. Balance 729 Mt (Proved 109 Mt + Indicated 620 Mt) are beyond 300m depth and has been proposed to be exploited by underground mining. Coal is of power grade quality and shall be used in Thermal Power plants of NTPC.
Mining Plan and Mine Closure Plan of Pakri Barwadih block has already been approved by Ministry of Coal for a targeted capacity of 15 Mtpa (Million tonnes
per annum). Environment clearance & Forest clearance has been granted by MoEF. Notifications under CBA Act for acquiring the land have been completed.
As per the approved Mining Plan the entire block is divided in four parts – Western Quarry, Eastern Quarry, area beyond 300m depth (Underground Area) & PB ‘A’.
As per the approved Mining Plan, total Mineable reserve in Western Quarry is 311.71 Million tones and 191.68 Million tonnes in Eastern Quarry. The total corresponding overburden/ interburden is 1238.49 million cubic meters & 860.29 million cubic meters respectively.
This contract is for mining in Western Quarry area of Pakri Barwadih Coal Block as per the scope of work.
MDO SCOPE OF WORK
The MDO shall undertake the mine development work and shall operate the mine. MDO is expected to develop, operate and maintain the mine to ensure a supply of coal to NTPC. This shall involve interalia excavation of various rocks/earth cutting by mechanised means, loading, transportation, dumping, dozing, mining of coal, crushing the coal to a
NTPC’s SCOPE OF WORK
NTPC’s scope of work includes providing Geological Report of the block, Approved Mining Plan and approved EIA/EMP. Notifications under CBA Act for acquiring the land have already been completed. Forest Clearance has also been granted by MoEF. NTPC shall also make payment towards land acquisition, various grants under R&R.
