[0002] When coal mining is carried out in a fully mechanized coal mining face, it is mostly necessary to use a hydraulic support for support, and coal mining is carried out while supporting. When coal mining in the fully mechanized coal mining face, the coal conveyor belt is arranged on the side of the hydraulic support base close to the coal mining face, the top beam of the hydraulic support supports the top of the mine shaft, and then the coal on the coal mining face is broken by a coal mining device. After being broken, the coal directly falls onto the conveyor belt, and the conveyor belt transports the coal out.

[0003] During the process of coal mining, whether the coal mining device breaks the coal on the coal mining face or the coal is transported on the conveyor belt, a large amount of dust will be generated. These dusts will fly towards the direction of the hydraulic support base and pass through the hydraulic support and disperse to the side of the hydraulic support far from the coal mining face, which not only affects the service life of the hydraulic cylinder on the hydraulic support, but also affects the physical health of the operators behind. In the prior art, although spray devices are used on the hydraulic support to spray water mist, due to the existence of the surface tension of the water droplets and the huge amount of dust, the spraying of the water mist at the hydraulic support has the problem of poor dust removal effect.
