Abstract：The traditional coal mine fire monitoring system mainly adopts the method of collecting gas samples underground and sending them to the surface,and a gas chromatography analyzer for component and concentration analysis.There are problems such as long anal-ysis cycle,long gas sample transportation distance,and difficult maintenance of gas pipelines.In response to this,a design scheme for a spontaneous combustion fire bundle tube monitoring and early warning system for underground coal mines based on the principle of micro chromatography analysis was proposed.Gas samples were taken from key areas such as goaf,working face,and high outburst area nearby,and sent it to the main station of the intrinsically safe fire monitoring system for mining for analysis of its composition and content.The a-nalysis results can be synchronously transmitted to the ground center station or underground display screen through the industrial Ether-net platform,providing scientific basis for coal mine fire monitoring and prevention work,and ensuring coal mine safety production.
