Abstract
The Permian coals of Ramagundam coalfield are sub-bituminous to high v olatile bituminous in rank on the basis of chemical (carbon, and volat ile matter) and petrographic as kerogen type-III. Reflectance (Rom) va lues suggest the maturation temperatures ranging from 46 degrees and 1 08 degrees C and depth of burial of coal bearing horizons varies from 1725 to 2175 metres.
