高抽巷瓦斯抽采治理上隅角瓦斯的研究与应用

Research and application of the methane drainage by high level suction tunnel management the Gas in upper corner

通过在采煤工作面使用高抽巷抽放采空区瓦斯,有效降低采煤工作面上隅角和回风流的瓦斯浓度,有效地改善了工作面的安全生产水平。通过对高抽巷的巷道布置、抽放效果和影响因素的研究与分析,总结出了高抽巷垂距和平距,减小采空区、高抽巷漏风,控制好高抽巷的抽放量等因素是影响高抽巷瓦斯治理效果的主要因素,为其他矿井高抽巷抽采治理上隅角瓦斯提供了参考。

Through the use of high level suction tunnel in the coal mining drainage the goaf gas, Effectively reducethe Gas concentration of the coal mining’s upper corne and Return air, Effective improvement safety productionlevel of the coal mining. Through application of the high level suction tunnel’s roadway layout, drainage effectand Influence factors, obtain the high level suction tunnel’s vertical distance and horizontal distance, reduce theventilation leakage of mined out area and high level suction tunnel is the main influencing factors of the high levelsuction tunnel’s drainage effect. These finds can provide reference for other coal mines.
