Background

Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and opencast coal mines. When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth's surface, the earth's surface layer is usually directly stripped to excavate coal, which is an open pit coal mine. The vast majority of coal mines in China belong to underground coal mines. Coal mines encompass a large area above ground and below ground as well as associated facilities. Coal mines are reasonable spaces excavated by humans when excavating geological formations rich in coal and generally include roadways, wells, and mining surfaces, among others. Coal is the most predominant solid fuel, one of the combustible organic rocks. It is formed by that the luxuriant plants grown in a certain geological age are gradually piled up into a thick layer in a proper geological environment, and are buried in the water bottom or silt, and then the thick layer is formed by the natural coalification of the long geological age. In the geologic periods of the world, most coal is produced in the stratums of the stone charm, the pilaster, the Jurassic and the third era, which is an important coal-forming era. Coal typically has a carbon content of 46-97%, is brown to black, and has a dull to metallic luster. According to the degree of coalification, coal can be classified into peat, lignite, bituminous coal and anthracite. After the coal is mined, the coal needs to be screened, so that impurities are filtered out, and coals with different sizes are screened out, so that the coals with different pricing and selling can be conveniently sold.
