Coal is a combustible rock with high carbon and hydrocarbons, formed over millions of years from plant material.

Types of Coal (Based on Carbon Content)

  • Anthracite: Best quality, high carbon (80-95%), rare in India (mainly in Jammu & Kashmir).
  • Bituminous: Most widely used, carbon content 60-80%, used in coke production.
  • Lignite: Brown coal, 40-55% carbon, high moisture, low heat.
  • Peat: Early stage of coal formation, low carbon content.
