In the process of coal mining, coal mining machines and roadheaders are needed. Coal mining machines are mechanical equipment that uses crushing rollers to peel coal from the ore bed and load it into the working face coal loading conveyor. Roadheaders are machines that dig tunnels in coal mines. When these equipment are working, a large amount of high-concentration coal dust will be generated. This dust will not only affect the health of workers and reduce their visual range, but also cause explosions when the dust concentration reaches a critical value. In order to ensure the life and health of workers and the safe production of industries and mines, the corresponding mining equipment will be equipped with air-water mixed spray dust suppression devices.
