[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people will choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is close to the surface, people generally directly peel off the surface soil layer to mine coal. This is an open-pit coal mine. In the prior art, most of the devices used for coal mining are large in size. They are mainly composed of a machine base, a coal scraper fixed on the machine base, and a conveyor belt. Although they can be used to mine coal, they are not only easy to damage the coal scraper, but also affect the efficiency of coal scraping.
