[0002] As we all know, coal is a solid combustible mineral that is gradually formed by ancient plants buried underground undergoing complex biochemical and physicochemical changes. Coal mining has always been the most arduous job. Due to the different burial depths of coal resources, there are generally two methods of mining: mine mining and open-pit mining. The reserves that can be mined in open pits in my country only account for 7.5%, which is mainly mine mining. Although there are many mining equipment at present, mining accidents still occur frequently. In addition, a large amount of dust will be generated in the process of coal mining, which affects the health of miners. Some mined mines cannot be mined on a large scale, and large-scale coal mining equipment cannot be used. Mining can only be done manually, with high labor costs and low mining efficiency.
