摘　　要：利用束管监测系统监测汾源煤业5-102综放工作面采空区氧气浓度变化情况,按照标准对综放工作面采空区自燃"三带"进行划分,并计算综放工作面的安全推进度,为工作面实现安全回采提供技术保障。监测结果表明,目前5-102综放工作面平均推进度为1.2 m/d。因此,工作面在采取开放式、连续性注氮措施的情况下,采空区自然发火危险性较低。The article proposes to use the beam tube monitoring system to monitor the oxygen concentration changes in the goaf of 5-102 fully mechanized caving face, Fenyuan Coal Industry, then divides the "three zones" of spontaneous combustion in the goaf of fully mechanized caving face according to the standard, and finally calculates the safety advancement of the working face,which provides technical guarantee for the realization of safe mining at the working face,with the current average advancing degree of 5-102 fully mechanized caving face is 1.2 m/d.
