Description

Technical Field

[0001] The present invention relates to the technical field of intelligent ventilation, and in particular to an intelligent ventilation device for coal mine electromechanical automation. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal. This is an open-pit coal mine. Most of my country's coal mines are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when digging geological layers rich in coal, usually including tunnels, shafts, and mining faces. Coal is the main solid fuel and a type of combustible organic rock. Intelligent ventilation devices are required during coal mining and processing.
