摘要
以马脊梁煤矿2107运输巷地质数据为基础,设计了2107运输巷的锚杆、锚索、W钢带压金属网联合支护方案,支护验算结果表明该支护措施满足巷道生产安全的各项指标。支护实践结果表明:该巷道断面无明显变形,围岩控制效果较好。
Based on the geological data of the 2107 haulage roadway in Majiliang Coal Mine,the combined support scheme of anchor bolt,anchor cable and W steel belt pressing metal net is designed.The support checking calculation results show that the support measures meet the requirements of the production safety of the roadway.The results of support practice show that the roadway section has no obvious deformation and the surrounding rock control effect is good.
