Application of Distributed Laser Methane Monitoring Device in Hulusu Coal Mine

Aiming at problems existing in the use of the coal mine methane sensor, the paper introduces the distributed structure characteristics, working principle of laser methane monitoring device, intelligent design and its performance characteristics. Through the application in Hulusu Coal Mine, compared with the traditional catalytic methane sensor, it has high accuracy, fast response speed, good stability and other advantages, and is more suitable for coal mine gas monitoring under complex environment conditions.
