运输顺槽巷道支护参数的优化设计

Optimal Design of Supporting Parameters of Transport Along-slot Roadway

针对运输顺槽顶板和巷帮变形量大的问题,以某煤矿运输顺槽为研究对象,在分析其顶底板情况和当前支护现状的基础上,基于自稳隐形拱理论对顶板锚杆、锚索以及巷帮锚杆的支护参数进行优化设计,并对比优化前后顶板的变形量。实践表明,支护参数优化后顶板的下沉量和巷帮的收敛量得到明显改善。

Aiming at the problem of large deformation of roof and roadway side of transportation trench, based on the analysis of its roof and floor condition and current supporting status, the supporting parameters of roof bolt, anchor cable and roadway side bolt are optimized based on the theory of self-stable invisible arch. The practice shows that the subsidence of roof and the convergence of roadway are obviously improved after the optimization of supporting parameters.
