综采工作面高位抽放巷的研究与应用

Research and Application of High Level Drainage Roadway in Fully Mechanized Mining Face

为了有针对性地解决“双突”矿井工作面回采与瓦斯治理平衡的难题,红阳三矿通过对瓦斯来源进行分析,在西一718采煤工作面提出了高位瓦斯抽放巷治理方案,辅以高位钻孔和采空区埋管瓦斯治理措施。经现场应用对比分析,高位瓦斯抽放巷的应用,提高了瓦斯抽放量及抽放率,并具有一定的吸能作用。

In order to solve the problem of the balance between mining in the working face and gas control of"double outburst"mine pertinently,Hongyang No.3 Coal Mine puts forward the control scheme of high level gas drainage roadway in the west one 718 coal mining working face by analyzing the source of gas.Supplemented by high level boreholes and buried pipe gas control measures in the goaf area.Through the comparative analysis of the field application,the application of the high level gas drainage roadway increases the gas drainage quantity and drainage rate,and has a certain effect of energy absorption.
