摘　　要：以高瓦斯矿井王坡煤矿3219综放工作面为研究对象,提出了本煤层顺层平行钻孔超前预抽、顶板裂隙带高位走向钻孔和采空区埋管边采边抽的瓦斯综合治理技术。现场实践结果表明:该技术有效地解决了综放面回采过程中上隅角和回风流中瓦斯浓度超限难题,上隅角和回风流中瓦斯浓度稳定在0. 8%以下,实现了工作面的安全高效生产。Based on the engineering background of 3219 fully mechanized caving face in a high gas coal mine（ Wangpo Coal Mine）,a comprehensive gas control technology is proposed,which comprises advance pre-drainage by parallel drilling through the coal seam,gas drainage in roof fissure zone with high level drilling along the strike,gas drainage during mining with buried pipe in goaf. Site practice results showed that, with the technology, the problem of gas concentration overrun in the upper corner and return air current was solved during top-coal caving process,and which was controlled under 0. 8%,the safe and efficient production was realized.
