The document discusses coal, how it is formed, types of coal, coal mining methods, and coal usage. Key points: - Coal is a combustible rock formed from compressed plant matter that lived hundreds of millions of years ago. - There are several types of coal defined by their carbon content, including anthracite, bituminous, sub-bituminous, and lignite. - Coal is mined through underground methods like shaft mining or surface methods like mountaintop removal. - India's coal reserves and production have increased in recent decades to support its growing electricity needs.
