摘要
针对贾家沟煤矿6107综采工作面无煤柱沿空留巷所存在的技术难题,提出了对6107运输顺槽采空区侧顶板实施切顶卸压,给出了切缝钻孔具体参数;并提出巷帮挡矸支护方案以及巷道超前支护和滞后加强支护;现场实践表明沿空留巷效果良好。
In view of the technical problems existing in the gob-side entry without coal pillar in 6107 fully mechanized mining face of jiajiagou coal mine,this paper puts forward the roof cutting and pressure relief for the side roof of goaf in 6107 transportation roadway,gives the specific parameters of slit drilling,and puts forward the roadway gangue retaining support,roadway advance support and lag strengthening support scheme.The field practice shows that the application effect of the gob-side entry technology is good.
