Description

TECHNICAL FIELD

[0002] Tunnel construction is an industry that is developing rapidly in society, and there are many harmful factors in tunnels that affect people's health. There are combustible materials such as coal and natural gas on some tunnel construction paths, and there may also be combustible gases such as gas in the coal seam. In the process of tunnel construction, the presence of natural gas and gas can easily cause fire and explosion risks, and the pollution of natural gas and gas in the air inside the tunnel can also cause people to suffocate. The main components of natural gas and gas are methane, ethane, propane, and hydrogen sulfide. At the same time, there are places prone to landslides on the tunnel construction path, and the geological hardness of some geological structures is low. These unstable factors pose a threat to the safety of construction personnel.

[0004] 1.

Therefore, a geological disaster early warning and protection system for tunnel construction is needed to solve this problem, which can conveniently detect the geological structure and hardness behind the tunnel face.

Therefore, a geological disaster early warning and protection system for tunnel construction is needed to solve this problem, which can detect whether there are combustible gases in the geology behind the tunnel face.

[0007] 4.
