摘要
屯兰矿属于煤与瓦斯突出矿井,瓦斯隐患给矿井安全生产带来严重的制约和影响。屯兰矿通过施工高抽巷、底抽巷等瓦斯抽采巷道,对开采层、上下邻近层及采空区瓦斯全方位抽采,形成"立体抽采格局",并全面使用简单可靠的"Y"、"U"型通风系统,有效地解决了矿井瓦斯浓度高的问题,为安全生产提供了保障。
Tunlan Coal Mine belongs to coal and gas outburst mine. The hidden gas hazard has brought serious restriction and infuence to mine safety production. Through the construction of gas drainage roadways such as high drainage roadway and bottom drainage roadway in Tunlan Coal Mine, a ＂three-dimensional drainage pattern＂ has been formed for gas extraction in all directions in mining strata, upper and lower adjacent strata and goaf, and a simple and reliable ＂Y＂ and ＂U＂ type ventilation system has been used in an all-round way to effectively solve the problem of high gas concentration in the mine and provides protection for safe production.
