[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. The vast majority of coal mines in my country are underground coal mines. The scope of coal mines includes a large area above ground, underground and related facilities. Coal mines are reasonable spaces excavated by humans when excavating geological strata rich in coal. They usually include tunnels, shafts, mining faces, etc. Coal mines are very easy to generate dust during the mining process, which harms the health of operators. Therefore, whether it is an underground coal mine or an open-pit coal mine, dust reduction is required during mining.

[0003] At present, when coal mines are subjected to dust reduction treatment, dust in the air is reduced by spraying water. Although water spraying has a certain dust suppression effect, a large amount of water needs to be sprayed, which will cause the mine tunnel to become humid. Water will gather in the low-lying areas of the mine tunnel, causing certain inconveniences to the workers. At the same time, water needs to be continuously supplied to the inside of the water tank, and the dust reduction equipment needs to be moved regularly, which is not convenient for injecting water into the water tank. Therefore, a multifunctional dust reduction equipment for coal mine development is proposed. Utility Model Content
