[0002] A coal mine refers to a place rich in coal resources, which is 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. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly peel off the surface soil layer to mine coal. This is an open-pit coal mine. Coal is the main solid fuel and a type of combustible organic rock. According to the degree of coalification, it can be divided into four categories: peat, lignite, bituminous coal and anthracite.

[0003] During coal mining, there is a lot of dust in the coal mine tunnels, which will affect the vision and have a certain impact on the health of the workers. When dealing with the dust, spraying is often used, but the ground after spraying will be relatively moist, causing the workers to slip when walking.

The coal mine tunnel dust prevention and reduction equipment based on coal mine exploitation can supply water to the atomizing nozzle through the provided bellows in cooperation with the provided water tank, so that the coal mine tunnel body can be sprayed for dust reduction treatment, and the dust can be isolated and treated. At the same time, by starting the provided rotating cylinder, the atomizing nozzle can be driven to rotate, so that when the atomizing nozzle rotates to the brush in the inner cavity of the mounting frame, the atomizing nozzle can be cleaned, thereby avoiding the phenomenon of clogging of the outer wall of the atomizing nozzle due to long-term work, and at the same time, the provided bellows can be adapted to the movement of the atomizing nozzle.

[0020] 2. The dust prevention and reduction equipment for coal mine tunnels based on coal mine exploitation can collect the sprayed water through the rainwater grate, and can prevent slipping when the staff walks on the top of the rainwater grate through the anti-skid bumps. The sprayed water can be collected uniformly through the installation box, and can be filtered by the filter.

[0021] 3. The coal mine tunnel dust prevention and reduction equipment based on coal mine exploitation can unfold the dust net by starting the first servo motor, so that the inner cavity of the coal mine tunnel body can be dustproofed, so that the dust can be isolated at one end of the dust net, and the rest of the coal mine tunnel body can be prevented from containing more dust.

The dust prevention and reduction equipment for coal mine tunnels based on coal mine exploitation can drive the fixed rod to rotate through the turning handle through the second driving component, and when the fixed rod contacts the contact plate, the dust net can be driven to shake. At this time, the dust net can be cleaned and the dust blocked in the dust net can be shaken off, so as to better filter and prevent dust. At the same time, the vibration amplitude of the dust net can be increased through the spring, so as to improve the filtering effect of the dust net.
