摘要
朱集煤矿1111(1)工作面轨道顺槽底抽巷顶底板为泥岩,属高应力软岩巷道,设计采用锚网索梁喷联合支护,并确定了支护参数。在巷道内设置了4个观测站,监测巷道两帮及顶底板的变形量。通过对矿压监测数据的分析,该支护方案有效控制了巷道的变形,尤其是纵向锚索梁对顶板变形的控制非常明显。
Based on the geological conditions of the bed plate tunnel in the 1111(1)working face of Zhuji Colliery,the support scheme and support parameters of the bed plate tunnel are designed.In order to monitor the deformation of two sides and roof in the tunnel,4 surface convergent observation stations are set up in the tunnel.The analysis of monitoring data shows that the support scheme can effectively control the deformation of the roadway.Especially the longitudinal anchor beam can control the deformation of tunnel roof effectively.
