摘　　要：渠里煤矿11010下巷掘进中,瓦斯涌出急剧增大,且带有动压现象。传统的瓦斯防治技术不能解决瓦斯超限问题。经分析研究,采用打超前钻孔配合煤层注水的瓦斯治理技术,有效解决了瓦斯超限问题,保证了安全生产,治理效果较好。In excavation of 11010 lower roadway of Quli Coal Mine, gas emission quantity rapidly increased, with ＂the phenomena of dynamic pressure. Traditional technology of gas prevention cannot solve the problem of exceeding gas. Through analysis and research, gas treatment technique of drilling in advance, combined with water infusion in coal seam was carried out, which can effectively solve the problem of exceeding gas and ensure safety in production. The reation effect is good.
