Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a coal mine ventilation auxiliary tool. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, the choice is generally to excavate the coal through tunnels underground, which is an underground coal mine. When the coal seam is very close to the surface, the choice is generally to directly remove the surface soil layer to excavate the coal, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. The scope of a coal mine includes a large area above and below the ground, as well as related facilities. A coal mine is a reasonable space excavated by humans when excavating coal-rich geological strata, usually including tunnels, shafts, and mining faces. Coal is the main solid fuel and a type of combustible organic rock. During coal mining, ventilation is required to ensure the safety of the personnel inside, so ventilation auxiliary tools are needed to ensure smooth ventilation in the coal mine.

[0003] However, existing coal mine ventilation auxiliary tools have the following disadvantages:

[0004] (1) A filter is usually equipped to filter the air circulating inside and outside, but the filter needs to be disassembled and cleaned for a long time, which is a cumbersome operation;

[0005] (2) Ventilation auxiliary tools usually use multiple bolts to install the device inside the ventilation duct. The installation process takes a long time and is not convenient for quick installation.

[0006] Therefore, the utility model provides a coal mine ventilation auxiliary tool. Utility Model Content
