摘要:
〗面对软岩巷道支护与维护的难题，提出桁架联合支护的思路。通过现场实测，分析围岩破坏特征；基于祁东煤矿巷道围岩的微观组成和力学参数，采用数值计算分析方法，对不同条件和参数下的巷道变形及应力分布进行模拟分析和支护参数优化，得出适用于沿空掘进软岩巷道的围岩控制方案，为软岩巷道支护提供理论指导，具有广泛的推广应用前景。
Abstract:
The think of girder combination support was put forward in order to solve the support and maintenance problem of soft rock roadway. The failure characteristics of roadway surrounding rock were analyzedwith onsite observation method. Based on the microstructure and mechanical parameters of roadway surrounding rock in Qidong Mine, the roadway deformation and stress distribution under different conditions and parameters were analyzed, and the support parameters were optimized by numerical calculation and analysis method. Then, the surrounding rock control scheme for soft rock roadway drivage along goaf was proposed, which provides a theoretical guidance for softrock roadway supporting and has a broad application prospect.
