[0002] Humans mine coal resources in coal-rich mining areas, which are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal, which is underground coal mines. During the mining and construction process of underground coal mines, drainage is an indispensable task. In order to prevent the drainage pump from being blocked by impurities such as coal slag in the tunnel, the coal slag in the liquid needs to be filtered.
