摘　　要：基于对采空区自燃"三带"理论和标准的分析,结合鲁西煤矿3下109工作面开采3下煤层时条件比较复杂,受3上109工作面采空区遗煤的影响较大,存在自然发火隐患的实际情况,采用在工作面和两巷埋设气体监测装置的方法进行了采空区自燃"三带"的研究。通过采集各测点的O2浓度数据,分析采空区O2浓度分布规律,掌握了3下109工作面采空区自燃"三带"的特征,对鲁西煤矿防灭火工作具有重要的指导作用。Based on the analysis of the theory and standard of spontaneous combustion 'three zones'in the gob,research on the spontaneous combustion 'three zones'in the gob was carried out by burying gas monitoring device in the working face and two gateways in combination with the actual conditions of more complicated mining condition of No.109 working face in the lower group of three coal seams,the greater influence of the left coal in the gob and the existence of spontaneous combustion danger.Through the acquisition of the oxygen concentration data at each measuring point and the analysis of the oxygen concentration distribution in the gob,the characteristics of the spontaneous combustion 'three zones'in the gob of No.109 working face was mastered,which has important guiding significance for the prevention and control of spontaneous combustion in Luxi Mine.
