摘要
为获得斜沟煤矿8号煤层超高压水力钻割一体化卸压增透最佳参数,以改善瓦斯抽采效率低下的现状,重点研究了最佳割缝压力、单刀出煤量与割缝时间之间的关系,并分析了瓦斯抽采纯量随时间的变化规律。
In order to obtain the optimal parameters of pressure relief and reflection improvement with the integration of ultra-high pressure hydraulic drilling and cutting in No.8 coal seam of Xiegou Coal Mine,so as to improve the status of low gas extraction efficiency,the relationship among the optimal slit pressure,single cutter coal output and slit time was studied,and the variation rule of gas extraction pure quantity with time was analyzed.
