为了解决工作面瓦斯经常超限的问题，通过向上隅角上方打钻和采空区埋管进行气体分析，确定了上隅角瓦斯主要来自于顶板裂隙带，通过设置低位钻向裂隙带施工拦截钻孔抽采有效解决了工作面上隅角瓦斯超限的问题，该方法对其他瓦斯矿井具有极大的借鉴意义。
為瞭解決工作麵瓦斯經常超限的問題，通過嚮上隅角上方打鑽和採空區埋管進行氣體分析，確定瞭上隅角瓦斯主要來自于頂闆裂隙帶，通過設置低位鑽嚮裂隙帶施工攔截鑽孔抽採有效解決瞭工作麵上隅角瓦斯超限的問題，該方法對其他瓦斯礦井具有極大的藉鑒意義。

In order to solve the overproof of gas concentration on upper corner of working face,a hole was drilled on the top of upper corner and a pipe was laid to make gas analysis as a gas mine. It can be identified that the gas comes from the water-flowing fractured zone on the roof. The gas overrunning was effectively was settled by setting low level drilling field and constructing interceptive hole. It affords other gas coal mine that merit attention.
