Abstract: In order to achieve the safety recovery of 1072 comprehensive mining face,the main parameters of the fire in the empty area were monitored by beam monitoring system,namely oxygen concentration,carbon dioxide concentration and temperature.Through the comprehensive analysis of the measured parameters of oxygen concentration,carbon dioxide concentration and temperature in the goaf area,the feasibility of the gas observation scheme of the observation pipeline arranged in the upper and lower lanes of the working surface is proved.This provides a basis for preventing spontaneous combustion and adopting scientific fire fighting techniques.
