[0002] Coal mining is to separate valuable coal from underground or the surface and transport it away from the site. Coal deposits occur in layers, with a wide distribution range, large reserves, brittle coal quality and easy to be cut and broken. During mining, there are often threats of disasters such as water, fire and gas. Compared with mining other minerals, coal mining technology has some different characteristics. The mining methods are divided into open-pit mining and underground mining.

[0003] A dust removal device for coal mining is disclosed in the related technology, including a box body. A plurality of fan blades are rotatably connected to the inner wall of the box body at equal intervals linearly. Driven gears are respectively fixed on the circumferential outer walls of the fan blades located on the upper and lower sides. Two driving gears are fixed on the circumferential outer wall of the fan blade located in the middle. A support is fixed on the back of the box body. A motor is fixed on the top of the support. Two rotating shafts are symmetrically fixed on the inner wall of the box body in a left-right symmetrical structure. A side door is rotatably connected to the circumferential outer wall of the rotating shaft. Two connecting blocks are symmetrically fixed on the side door in a front-back symmetrical structure. A water tank is slidably connected to the inner wall of the side door.
