Technical Field

The utility model relates to the technical field of coal mine environment detection, in particular to an underground coal mine environment detection device.

Background

Coal mines are areas where mankind is mining coal resources in coal-rich mining areas, and are generally classified into underground coal mines and open pit coal mines. When the coal seam is far from the earth surface, coal is generally selected to be extracted from underground mining roadways, which is an underground coal mine. When the distance between the coal seam and the ground surface is very short, the earth surface soil layer is generally stripped directly to excavate coal, and the coal is an open pit coal mine. Most of coal mines in China belong to underground coal mines.

In coal mining, phenomena of coal mine explosion and asphyxiation of workers sometimes occur. Along with the continuous tunneling of mine tunnel, the concentration of gas can rise gradually, and the danger of explosion is also stronger more and more, and oxygen concentration drops, and the staff appears the oxygen deficiency easily, even suffocates, so all need survey the air in the underground coal mine before carrying out exploitation to judge whether can carry out exploitation, current detection device detects at every turn and can only carry out single detection to the air in the certain degree of depth, makes the staff meet the higher region of gas concentration in the way of going down the mine easily, causes the unexpected accident.
