易风化软岩巷道支护技术研究

摘要

Aiming at the mine rock roadway that was affected by the easily weathered mudstone, the roadway surrounding rock has low strength, the original roadway support effect is poor, and the parameters of bolt and cable were studied and optimized, designed the supporting scheme at last, the industrial test results show that roadway supporting effect is good, the deformation of the surrounding rock has been effectively controlled.%本文针对某矿岩巷段受易风化泥岩影响，巷道围岩强度低，原巷道支护效果不佳的情况，对锚杆（索）参数进行了研究优化，最后编制了支护设计方案，现场工业性试验结果表明，巷道支护效果良好，围岩变形得到有效控制。
