摘　　要： 针对平朔井工一矿4109工作面漏风现象,基于SF6气体的示踪原理,采用瞬时-连续联合释放法对4109工作面内-外漏风进行系统分析。试验结果表明,4109综放工作面外部漏风通道主要是地表裂隙通道,内部漏风主要来自于采空区和回风巷,并进一步计算出漏风量和漏风率,为矿井火灾的防治提供了依据。 Aiming at the air leakage problem in 4109 work face of Pingshuo Underground No. 1 Mine, based on the tracer principle of SF6 gas, the instantaneous-continuous joint releasing method was used to systematically analyze the internal-external air leakage of 4109 work surface. The experimental results showed that the external air leakage channel of 4109 fully mechanized caving face was mainly surface fissure channel, while the internal air leakage channel was mainly from the gob and return air road- way. Besides, the air leakage amount and leakage rate were measured to provide the basis for prevention and control of mine fire.
