摘要
通过分析矿井瓦斯治理存在的主要问题,采取工作面本煤层长距离走向钻孔、本煤层倾向钻孔、顶板走向长距离高位抽放钻孔、抽放系统,实现了高、低负压分源抽放等一系列的治理措施,有效地杜绝了综采工作面上隅角瓦斯超限问题,保证了采面的安全高效回采,为矿井的高产高效提供了支持,钻孔抽放技术可为该矿及其他矿井类似地质条件的工作面瓦斯治理,提供参考。
Huangbaici coal mine gas control has made a lot of work in recent years, by analyzing the mainproblem of mine gas control, then taking a series of measures as: coal seam working face long distances todrilling, coal seam drilling tendency, roof towards to long-distance and high drainage hole, and drainage sys-tem achieved the high and low negative subsection source drainage and so on. It eradicates the fully mecha-nized working face transfinite gas problem effectively, to guarantee the mining safety and efficiency of themining, and provides the support for high yield and efficient mine. Drilling drainage technology provides refer-ence to the mine and other similar mine geological conditions of working surface gas control.
