the coal may be divided into following classes:

1. Anthracite: It is the best quality coal and its carbon content is as much as 92% with a low volatile matter and very little moisture. It is hard and heavy and burns with great heat.

2. Bituminous: It is also of good quality coal next to Anthracite. It’s carbon content is up to 85%. Coal mined in India, is mainly of bituminous type of Gondwana age.

3. Lignite: It is inferior quality coal, full of moisture and volatile matter. Its carbon content is less than 50%. It is also known as ‘brown coal’.

4. Peat: It is the first stage in the formation of coal. It is light and woody and has poor heating capacity.

ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users (e.g., for power generation and coke manufacturing) and to researchers studying the origin of coal.
