Abstract: In the process of China’s coal mine engineering, underground coal mining will encounter gas from the coal body. This kind of gas is usually called mine gas, and its main components are methane, other hydrocarbons and carbon dioxide. The disaster of coal mine gas directly restricts the safety production of coal mine. In the past ten years, there are nearly 70 explosion and accidents caused by coal mine gas. Many accidents occur because that the concentration of coal mine gas is not detected correctly, which leads to gas explosion, causing a large number of casualties, and damaging underground production and safety facilities, and affecting the normal production progress. It can be said that in the process of China’s coal mine engineering safety work, the mine gas problem has always been a key and difficult problem. At present, China’s coal mine gas problem has been widely valued by the State Coal Mine Safety Supervision Bureau. Therefore, in order to better control the coal mine gas disaster, it is necessary to fully analyze the effective technical application of gas detection of the main components of coal mine gas in coal mine engineering. That is, to detect the main component of methane in coal mine gas, and analyze the concentration of methane gas in coal mine engineering. It also has a certain guiding role for the effective application of coal mine methane detection technology.
