采煤工作面回风隅角瓦斯积聚治理技术研究

Control Technology of Gas Accumulation in Return Air Corner of Coal Mining Face

煤矿安全生产存在较为严重的安全隐患,即采煤工作面回风隅角瓦斯的积聚和超限,因此,煤矿企业需要加强对采煤工作面回风隅角的管理。分析了回风隅角的瓦斯来源及积聚原因,并提出了一系列瓦斯治理措施,以期解决回风隅角瓦斯积聚问题,避免其超限,从而影响煤矿的安全性。

There are serious safety risks in coal mine safety production,that is,the accumulation and overlimit of gas in the return air corner of coal mining face.Therefore,coal mining enterprises need to strengthen the management of the return air corner of coal mining face.The gas source and accumulation reasons in the return air corner were analyzed,and a series of gas control measures were put forward to solve the problem of gas accumulation in the return air corner and prevent it from exceeding the limit,thus affecting the safety of coal mine.
