摘要
寺河煤矿二号井以151306综采工作面的钻孔和密闭墙作为研究主要对象,对支管路浓度、负压、流量等相关抽采参数测量分析,总结出抽采系统浓度提高、下降的内在关系,为高瓦斯矿井提高抽采浓度指出了方向。
The 151306 fully mechanized working face of the No. 2 Well drilling and sealing wall as the research object in Sihe Coal Mine,the concentration of the pipeline,pressure,flow and other related parameters extraction measurement analysis,summed up the concentration of extraction system,decreased the inner relations,pointed out the direction for enhancing gas mine extraction concentration.
