Distribution of Coal in India
Distribution of Coal in India
Occurrence: Major coalfields in India lie East- West , starting from a point approximately 185 km NW of Kolkata (Calcutta) and streaching ewestward. Distribution of coals in India can be subdivided into a) Lower Gondowana Coalfields, b) Upper Gondowana Coalfields, c) Tertiary Coalfields. The tables below show over all distribution of coalfields in India.
Gondowana Coals are most important in India and account for more than 90% of coal production in country. The land mass of southern hemisphere was united with South Africa, India, Australia and possibly South America. India drifted north-east relative to Africa and the Gondowana landmass was exposed to sub-aerial conditions for a long period of time. The initiation of Gondowana period is marked by a glacial period (evidenced by Talcher Series). Climate changed to a more temperate condition in later period melting snow and allowing prolific growth of vegetation. This huge vegetation got buried and produced Gondowana Coals. The land subsidence began in the east giving rise to a great depth of Barakar and Ranigunju measures. The great depth along with earth movement allowed the coal seam to lose moisture and volatile matter and change in chemical conditions and sometimes converted to coke (example: Barakar Strata). To the west, subsidence was less as evidenced by thin and poor quality coal seams.
Tertiary Coals contribute very little of the total coal production in India. They usually have high sulfur content (2-8%).

Note: It is really very hard to find any good book on coals in India. I have used “Advanced Coal Mining” by B.M Vorobjev and R.T Deshmukh published in 1964! If you know some good reference other than the book I mentioned, please let us know.

Hi Ankan, Thanks for sharing Distribution of Coal in India.
Could you please manage to give some porosity permeability data of Barakar Sandstone of Damoday Valley Coal Fields? and Cross Sections, Coal Characters, maps of Singrauli Coal Fields? If not then please let me know where i can find all these…
