Question : How would you classify the types of coal depending on the degrees of compression? 

Answer : Following are the types of coal depending upon the degree of compression:
i. Peat: Decaying plants in swamps produced peat, which has a low carbon and high moisture contents. It has very low heating capacity.
ii. Lignite: Lignite is a low grade brown coal, which is soft with high moisture content. The principal lignite reserves are in Neyveli in Tamil Nadu and used for generation of electricity.
iii. Bituminous: Coal that has been buried deep and subjected to increased temperature is bituminous coal. It is the most popular coal in commercial use.
Metallurgical coal is high grade bituminous coal which has a special value for smelting iron in blast furnace.
