摘　　要：兖州煤业杨村煤矿314综放工作面周围存在老空区和老巷,可能存在漏风通道,具有自然发火的隐患。针对示范矿井具体情况,为了预防综放工作面周边老空区和老巷的自然发火,利用SF6示踪气体查找了工作面和胶带运输巷的漏风通道,并定量测定了漏风量,为矿井检测漏风通道提供了新的技术手段,同时还为防治自然发火提供基础参数。There are several mined-out areas and abandoned workings around 314 fully mechanized caving face in YangcunMine of Yanzhou Mining Group Co. , Ltd., where the air leakage channels may exist, which were the hidden danger ofspontaneous combustion. To counter to the specific conditions of the demonstration mine and in order to prevent the spontaneouscombustion in the mined-out areas and abandoned workings around the fully mechanized caving face, SF6 tracer gas was used tofind the leakage channels in the working face and belt-haulage roadway and the quantitative measurement was made on the airleakage, which provided not only a new technical means for detecting mine air leakage channels, but also basic parameters for theprevention and control of spontaneous combustion.
