Bokaro Ramgarh Coalfields Railways

Background

The Bengal-Nagpur Railway(BNR) entered the Jhariah coalfield (see separate page) in 1904 and it was recorded that “the subsequent extension of various loops and small branches, besides innumerable small sidings from both Railway systems and the East Indian Railway ‘EIR Grand Chord’ from Dhanbad to Gomoh which opened in 1907, enabled full development of every part of the coalfield, including the extension to the west towards the Bokaro Ramgarh Coalfields [1].

The ‘East Bokaro Coalfield’, covering an area of 208 sq km, was developed first to supply the railways. The main source of coal, even to the present time, is the 21-23m thick Kargali seam. The Bokaro colliery was opened in 1917. [2] .
The ‘West Bokaro Coalfield’ and the ‘Ramgarh Coalfield’ were developed later.

In 1917, L.S.S.O’Malley described the coalfields in the upper reaches of the Damodar as follows: "Near the western boundary of Jharia field is that of Bokaro, covering 220 sq.miles(570sq.km}, with an estimated content of 1,500 million tons; close by… is the Ramgarh Field, 40 sq.miles, in which, however, coal is believed to be of inferior quality. A still larger field in the same district is that called Karanpura, which extends over 544 sq.miles(1410sq.km} "and has an estimated capacity of 9,000 million tons."[3] [4] .

The Coalfields

The ‘Bokaro Coalfield’ is 40 miles(65km) from east to west and 6½ to 10 miles(10 to 16km) from north to south. ‘Bokaro West’ and ‘Bokaro East’ are two subdivisions of the field separated almost in the middle by Lugu Hill, height 3150 feet(960mtr) [5]

The ‘Ramgarh Coalfield’ covers an area of 38 sq.miles(98sq.km) and has total coal reserves of 1,059.20 million tonnes.[6] [7] .

Railways

The following railways are relevant to the ‘Bokaro Ramgarh Coalfields’
