摘　　要：为了实现1072综采工作面的安全回采,在采煤工作面采用束管监测系统监测采空区发生火灾的主要参数,即采空区氧气浓度、二氧化碳浓度和温度等。通过对实测的采空区氧气浓度、二氧化碳浓度和温度等参数进行综合分析,证明了在工作面上下平巷布置的观测管路观测气体方案的可行性,为防止采空区遗煤氧化自燃和采取科学的防灭火技术提供了依据。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.
