Background

Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and opencast coal mines. When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine. The vast majority of coal mines in China belong to underground coal mines. The coal mining methods are of various types, and the coal mining methods used in the world in the main coal producing countries are generally divided into two main types, namely wall type and pillar type. The two different types of coal mining methods are greatly different from both coal mining systems and mining processes.

No matter which coal mining method is adopted, a large amount of coal dust generated in the coal mining production process is filled in the whole operation site, particularly when the fully-mechanized excavating machine is constructed, the amount of the produced dust is the largest, the visibility of the operation site is reduced due to the large amount of the coal dust, the operation safety is affected, and workers work in the dust-filled environment for a long time and suck certain dust more or less, so that pneumoconiosis can be caused in the past, and the health of the workers is damaged.
