摘　　要：根据朱集西矿13501工作面轨道顺槽顶板离层观测结果,较全面地阐述了掘进、锚网支护参数采动影响程度等对巷道顶板围岩稳定性的影响。现场实测结果表明,锚网支护参数优化后,顶板离层量明显减小,巷道顶板得到了较好的维护。According to the observation results of track along-groove roof separation in the 13501 working face of Zhujixi Mine,the influence of excavation,bolting and mesh support parameters on the stability of roadway roof surrounding rock is expounded in this paper.The field measurement results show that after the optimization of bolting and mesh support parameters,the amount of roof separation is obviously reduced,and the roadway roof is well maintained.

关 键 词：掘进 顶板 离层 稳定性
