coal classification | Types & Facts | Britannica

Coal classifications are important because they provide valuable information to commercial users (eg, for power generation and coke manufacturing) and to researchers studying the origin of coal The most common classification is based on rank, referring to the degree of coalification that has occurredCoal - Wikipedia,Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams The classification of coal is generally based on the content of volatiles However the most important distinction is between thermal coal (also known as steam coal), Coal Classification | General | Lignite | Bituminous Coal ,Coal Classification When it comes to coal classification, there are 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
