Royal Commission on Labour in India: Report(1929)||
Coal is worked in Assam, Baluchistan, Bengal, Bihar and Orissa, the Central Provinces and the Punjab; but the great bulk of the collieries of India are concentrated in a comparatively small area, the outlying fields being of much less importance. The Raniganj, Jharia and Bokaro fields, which together produce nearly 90% of the present total coal output, lie in a narrow strip running roughly from Raniganj in Bengal (about 160 miles north-west of Calcutta) westwards for about a hundred miles. Adjoining them still further to the west is the less important but expanding Karanpura field, while about 50 miles to the north of the Jharia field is the Giridih field. The greater part of the Raniganj field lies in Bengal; the remainder of it and all the other fields mentioned are in the Chota Nagpur division of Bihar and Orissa. The figures of output, in tons, for these fields and for the remainder of British India in 1929 are given below: ---
|Bokaro||2,119,000||Rest of India||1,337,000|
The last item includes 680, 000 tons from the Pench Valley field in the Central Provinces. The industry meets the present internal demands of India, and both the export and import of coal are on a small scale at the present time. The efforts which have been made in recent years to recover the export trade have been\ materially assisted by the co-operation of Government with the industry in the work of the Coal Grading Committee.
