摘　　要：对影响采空区漏风及上隅角瓦斯积聚的因素进行分析研究的基础上,结合24307工作面的基本情况,建立了M形通风三维仿真模型,并研究了不同配风情况下的采空区瓦斯流动规律,结果表明当主副进风顺槽风量比近似为5∶2时,可有效缓解上隅角瓦斯积聚。Studied the affecting factors of the gas accumulation at upper corner and goaf air leakage,then, established 3D simulation model of M type ventilation about. 24307 working face in Shaqu coal mine in order to research M type two into one ventilation mode working face and goaf gas flow patterns.Finally,comparison and analysis the gas flow rule under the different air volume in main and auxiliary intakes. Studies have shown that in M face ventilation system, when the main and auxiliary air volume ratio is about 5∶2, which can effectively alleviate the problem of gas accumulation at the upper corner.
