摘要
顺和煤矿西翼皮回一联巷揭煤区域瓦斯局部赋存不稳定,治理难度大,为解决石门快速安全揭煤问题,通过对西翼皮回一联巷揭煤采取"穿层为主+顺层为辅"的瓦斯抽放区域防突措施,推广应用穿层钻孔水力冲孔增透技术,揭煤时采用先掘进对侧巷道待揭煤层,将煤巷段掘进结束(4.5 m),然后从岩巷段掘进,在揭露煤层的同时与对侧已掘煤巷硐室贯通,实现安全揭煤.
Abstract
Aiming at the local gas occurrence in the uncovering area of a connecting tunnel in the Western Wing of Shunhe Colliery,the author proposes the hydraulic punching anti-reflection technology through layer drilling with the regional outburst prevention measures of"giving priority to layer drilling and bedding for auxiliary",in which the coal seam to be uncovered in the opposite roadway is excavated first,and the driving of the coal roadway section is completed(4.5 m);and then when excavating from the rock roadway section to expose the coal seam,it is connected with the coal roadway chamber on the opposite side to realize safe coal uncovering in crosscut.
