摘　　要：塔山矿是高瓦斯矿井,为了防止瓦斯爆炸等事故发生,矿井采用顶板抽放巷抽放瓦斯。但在瓦斯抽放过程中抽放巷内瓦斯浓度经常超过2.5%,给安全生产带来隐患。为解决瓦斯高涌出问题,论文提出采用地面L型钻孔抽采瓦斯技术,通过L型钻孔抽采瓦斯技术可使顶抽巷瓦斯浓度下降1%左右,分担了工作面顶抽巷压力,保证了矿井的安全生产。Tashan mine is a high gas mine. In order to prevent gas explosion accident, the mine draws out gas with high drainage roadway on the roof strike. But the gas concentration is more than 2.5% in the gas drainage process usually. And it brings hidden dangers to the safety of production. For solving the high gas emission in high drainage roadway, the paper proposes ＂L-type＂ Drill Gas Drainage Technology. The gas concentration decreased by 1% in high drainage roadway after using ＂L-type＂ Drill Gas Drainage Technology. And it ensures mine safety production.
