Abstract: Methane produced in underground coal mining will pose a serious threat to the safety of coal mines. Real -time
monitoring and control of methane concentration has important application value. According to Lambert-Beer's law, the non-contact
measurement of methane concentration was carried out by tuning and controlling the wavelength of laser, and the monitoring system
was designed, which can realize the real-time display and control of underground methane concentration. At the same time, the
modular design method was adopted to facilitate the layout and application in the underground.

Key words: methane concentration; monitoring system; tuning laser; air chamber; real-time monitoring
