Coal occurs in two horizons, Raniganj & Barakar Fms
Raniganj Formation is widely and better developed than Barakar
Formation
Barakar coals are generally medium coking, upper coal seams
like Chanch, Laikdih are excellent
Lower Raniganj coal seams like Dishergarh, Sanctoria are semicoking while Middle & upper seams yield superior quality non
coking coal
More than 10 billion tonne coal is of Superior qualty

CRITICAL ANALYSIS OF RESOURCE BASE
NO SCOPE FOR COMPLACENCY IN LONG TERM
All geological resources - not mineable
All mineable resources – not recoverable
CONSIDERABLE PART IS BEYOND THE LIMIT
OF COST EFFECTIVE MINING AT PRESENT
