Background

With the increasing difficulty of coal mining, the problem of gas outburst is more and more serious, and in order to solve the problem, the most ideal method at the present stage is to adopt a punching technology. After the gas drainage hole is drilled, high-pressure water is injected to flush the inside of the coal bed into a cavity, so that the diameter of the drilled hole is effectively increased, the air permeability of the coal bed is enhanced, and the gas is released favorably. However, a large amount of gas, water, coal slag and the like are generated in the punching process, and the gas, the water, the coal slag and the like are mixed together, so that the collection and the discharge of the gas are inconvenient. In addition, problems such as gas outburst and spray holes are encountered. In addition, the large amount of water used is mixed with coal slag and the like, so that the environment of a punching site becomes severe, and the punching technology is difficult to be widely applied due to the problems.

Coal mine underground workers can easily get pneumosilicosis due to working in the environment full of coal dust for a long time, and the direct harm is brought to the health of coal mine workers. The coal slime sewage contains a large amount of coal, and if the coal slime sewage is not treated, the resource waste is caused.
