Coal classification, any of various 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.

Bituminous Coal – This coal is dark and hard. This coal is formed when a sub bituminous coal undergoes a higher level of organic metamorphism. The carbon density of this coal is higher and accounts nearly 77 to 87 percent in a dry ash free basis; it is further divided into low volatile, high volatile and medium volatile types.
Approximately 3.2% of the total world reserves of lignite/sub- bituminous coal are in our country. In addition as the grade of a large portion of our lignite is low, its use in thermal plants has stood out. Approximately 46% of the lignite reserves in our country are located in the Afsin – Elbistan basin.
