西曲矿近距离煤层回采巷道支护技术探析

Study on Support Technology at Mining Roadway in Close-distance Coal Seams in Xiqu Colliery

本文针对西曲矿下组煤近距离开采条件下9#煤层回采巷道支护技术的实际工程问题,对29106工作面轨道巷顶板围岩稳定性进行分析后,确定采用锚网索联合支护,并布置两个矿压监测站对支护效果进行日常跟踪,矿压监测数据结果显示,采用该支护方案能够使巷道围岩保持相对稳定,满足工作面安全回采要求。

By analysis of the stability of roof surrounding rock in track roadway at 29106 working face under close-distance mining condition in Xiqu Colliery,the author proposes the combined bolt-mesh-cable support,which has been proved to keep the roadway surrounding rock relatively stable and meet the requirements of safety mining of working face by tracking the support effect daily through two monitoring stations.
