摘要
为解决东周窑矿8105综放工作面5105回风巷道小煤柱沿空掘巷动压巷道支护难题,根据已掘巷道支护和变形情况,确定采用高预应力全锚索组合支护系统,并针对掘巷过程中不同地段地质构造条件,有针对性的调整支护方案,加强巷道支护,取得了较好的效果。
In order to solve the problem of roadway support of the 5105 return wind roadway with small coal pillar along the roadway of the 8105 fully mechanized caving face in Dongzhouyao Mine,according to the condition of roadway support and deformation,the combined support system of high prestress full anchor cable is adopted.And aiming at the geological structure conditions in different sections of the excavation process,the targeted adjustment support scheme,strengthening the roadway support,and obtaining better roadway support effect.
