[0002] In coal mining operations, the underground environment is complex and dust pollution is a serious problem. Large amounts of dust are generated in various stages of coal mining, transportation, and transshipment. This dust permeates the underground space, posing a serious threat to the health of workers and production safety.

[0003] Prolonged exposure to high concentrations of dust can easily cause workers to inhale large amounts of fine dust, which, over time, significantly increases the risk of respiratory diseases such as pneumoconiosis, severely damaging their health. Furthermore, coal dust is flammable and explosive; when the concentration of coal dust in the air reaches a certain level, it can trigger an explosion upon contact with a source of ignition, causing devastating disasters in the mine and resulting in enormous casualties and property damage.
