摘要
以王村矿2301切眼(导硐)为案例研究了深部高应力巷道高强支护技术的实践应用,设计了巷道高强支护方案,并通过计算确定了高强支护参数。现场观测数据结果表明:2301切眼(导硐)巷道最大顶底板变形量、两帮变形量都较小,高强支护方案有效地控制了巷道围岩的变形量,高强支护方案设计合理。
Taking 2301 cut off (pilot tunnel) of Wangcun Coal Mine as a case study,the practical application of high-strength support technology in deep high stress roadway is studied,and the high-strength support scheme is designed,and the high-strength support parameters are determined through calculation.The results of field observation show that the maximum deformation of roof and floor and the deformation of both sides of 2301 cut off tunnel (pilot tunnel) are small.The high-strength support scheme effectively controls the deformation of surrounding rock,and the design of high-strength support scheme is reasonable.
