Description

Technical Field

[0001] The utility model relates to the technical field of end head structures, in particular to a safety protection device for mining gas. Background Art

[0002] Gas mines are ore bodies with harmful gases mainly composed of methane, which are composed of coalbed methane. Gas is lighter than air, easy to diffuse, and has strong permeability. It is easy to pass through the rock layer from the adjacent layer and be released from the goaf. The gas itself is non-toxic, but it is not breathable. When the gas concentration in the air in the mine exceeds 50%, it can cause people to suffocate and die due to lack of oxygen. Gas can burn or explode. Gas explosion is one of the main disasters in coal mines.

[0003] Therefore, it is necessary to monitor the current environment before discovering and collecting gas. Therefore, some devices need to be placed under the mine to observe and monitor whether the current environment is safe and whether it is possible to mine manually. A single monitoring device can only monitor vertically underground or around the underground, and cannot monitor remotely underground. Therefore, we proposed a safety protection device for mine gas to improve the above problems. Utility Model Content
