摘要
锚网支护近年来已推广应用于煤矿采掘巷道的控顶,大断面、高地应力、复合顶板地质条件下的煤巷锚网支护成为锚网支护技术的一项重点与难点研究项目。结合羊泉煤业3107回风顺槽煤巷大断面、复合顶板锚杆支护技术进行研究,实践证明锚网支护在大断面、高地应力、复合项板地质条件下应用成功。
Boll-mesh supporting technology has already applied in the roof control of coal extracting roadway in recent years.The bolt-mesh support of coal roadway with large section,high stress and composite roof become a major and difficult issue of boll-mesh supporting technology.The bolting technique of 3017 return roadway with composite roof and large section of Yangquan coal company was studied,and the production practice proved that the bolt-mesh supporting technology was successfully used in the conditions of large section,high stress and composite roof.
