[0002] Coking coal is a kind of bituminous coal. It is customary to have a certain degree of cohesiveness and can form coke under the coking conditions of chamber coke ovens. The raw coal used to produce a certain quality of coke is collectively called coking coal. According to my country's coal classification standards, lean coal, lean coal, coking coal, fat coal, gas-fat coal, and gas coal in bituminous coal all belong to coking coal. As the name suggests, coking coal is mainly used for coke. It is usually divided into metallurgical coke (including blast furnace coke, foundry coke and ferroalloy coke, etc.), gasification coke and calcium carbide coke, etc. according to its use. The production of coking coal is directly related to heavy industrial sectors such as metallurgy and coal chemical industry and some industries such as electricity and city gas. It has an important impact on the long-term development of the country's entire industrial system and people's lives. Moreover, coal is a non-renewable resource. From the perspective of the scientific, harmonious and sustainable development of the national economy and society, it is necessary to study its reasonable development scale and protection.
