Description

Technical Field

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, generally, underground roadways are excavated to mine coal, which is an underground coal mine. When the distance between the coal seam and the surface is very close, generally, the surface soil layer is directly stripped to excavate coal, which is an open-pit coal mine. Most coal mines in China belong to underground coal mines. The scope of a coal mine includes a large area above and below the ground and related facilities. A coal mine is a reasonable space excavated by humans when excavating a coal-rich geological layer, usually including roadways, shafts, and working faces, etc.

The ventilation structure needs to be equipped with a filter screen to filter the air in the mine shafts before discharging it. After long-term use, coal dust will adhere to the surface of the filter screen. The long-term accumulation of coal dust will block the filter screen, reducing the use efficiency of the ventilation filtering structure.

[0004] Therefore, it is necessary to design and transform the ventilation filtering structure to effectively prevent the filter screen from being blocked. Content of the Utility Model
