【 Credit Note-Industry Sorting 】 Analysis on the Characteristics of Fourteen Coal Bases in Coal Industry
Coal in China is mainly divided into power coal, coking coal and anthracite according to its use. The indexes that determine the quality of different kinds of coal are as follows: The most important index of thermal coal is calorific value index, and the indexes such as ash and moisture will affect calorific value. The most critical index of coking coal is caking index, which is the main index to determine whether coal can be used for coking. Anthracite should focus on fixed carbon content, and the higher the index, the higher the calorific value.

Summary:

? On the whole, Shendong Coal Base is the base with the largest proven coal reserves and output in China, spanning Shaanxi and Inner Mongolia provinces, with high-quality thermal coal as the mainstay. Shanxi Province, the three major coal bases from north to south, has excellent coal quality and relatively good mining conditions, and is the largest transit base for thermal coal, coking coal and anthracite in China. There are many open-pit coal mines in northeast Inner Mongolia, but the coal quality is poor. Huaibei base in Anhui Province has relatively complete types of coal, close to the economic hinterland, but the mining time is long and the sustainable mining capacity of coal resources is poor. Coal resources in Jizhong coal base and Henan coal base in Hebei and Henan provinces also tend to be exhausted. Ningxia and Xinjiang are rich in coal types, but far from the eastern coal demand area, which is the resource reserve base of China's energy strategy to the west. The geological mining conditions of Yunnan-Guizhou coal base are relatively complicated, and the coal contains sulfur, high moisture and poor quality.
