摘要
以七沟矿软岩巷道工程为背景,通过现场工程地质调查和试验研究,运用软岩工程力学原理,对软岩巷道围岩变形与破坏力学机理进行分析,并采用数值模拟方法,对巷道支护结构体系、支护工艺进行优化,最终确定了适用于该矿软岩巷道的支护形式,确保了巷道围岩的稳定性。
Based on the engineering of soft rock roadway Qigou Coal Mine, through on - site engineering geological survey and experi-mental research, using the soft rock engineering mechanics principle, carries on the analysis to the Qi Gou coal mine soft rock roadway deformation and failure mechanism, and according to the actual situation of soft rock roadway Qigou Coal Mine, using the method of nu-merical simulation method and on the roadway supporting structure, supporting process optimization, and ultimately determine the suit-able supporting form Qigou Coal Mine soft rock roadway, to ensure the stability of roadway surrounding rock.
