With the acceleration of mechanized production efficiency of coal mines, a large amount of dust is generated in the processes of mining, crushing, screening, transporting, storing, breaking coal rocks and the like of coal. According to measurement, especially in the wide use of modern advanced fully-mechanized mining technology, the mining amount of coal is greatly increased, but the coal dust generated at the same time is rapidly increased, so that the concentration of the coal dust in the well is increased, and fully-mechanized mining is realizedAnd the coal dust concentration of the driving face reaches 1400mg/m3Above, some coal mines have even higher dust concentrations. In the process of transporting and mining coal, a large amount of coal dust can be generated, the environment can be polluted, and the human body can be injured, so that the problem of pollution of the coal dust to the environment and the human body is urgently needed to be solved. At present, water sprinkling and dust suppression are the most main measures applied to coal mine dust removal in China, but coal dust has hydrophobic property, is not easy to be wetted by water, is difficult to control the pollution of the coal dust in coal mining, and is expensive.
