Importance and types
Coal is India's dominant commercial fuel for electricity, steel (coke), cement and industry. Indian coals are mainly Gondwana (Permian; coking and non-coking) found in peninsular river valleys, and Tertiary coals in the North-East. Lignite (brown coal) occurs in younger sedimentary basins.
Production—general features
Most output comes from opencast mines (high productivity); underground mining is limited. Public sector companies, especially Coal India Ltd. (CIL) and its subsidiaries, dominate production alongside Singareni Collieries (Telangana). Power utilities consume the bulk; coking-coal quality limits require imports for steel blending. Indian coals are often high ash (affecting efficiency) and need beneficiation.
