摘要
本文以万峰煤矿1209掘进工作面地质条件为背景,采用FLAC^(3D)有限差分计算软件,通过分析巷道顶板围岩破坏范围和特征,确定万峰煤矿巷道支护合理参数。分析结果:万峰煤矿现有的支护参数不能有效的控制巷道围岩的变形,巷道围岩塑形区超过锚杆支护长度;现有支护参数无法满足巷道围岩稳定性控制。本研究为复合顶板巷道支护参数优化和设计具有一定指导作用。
1209 mining face of Wanfeng Mine was taken as example,FLAC^（3D） finite difference computing software was adopted,damage scope and features of roof surrounding rock were analyzed to settle reasonable roadway support parameters. The result showed that the current support parameters cannot meet the needs of controlling deformation of surrounding rock,surrounding rock shaping area of roadway exceeded the length of anchor bolt support,the result provided reference for support parameter design of compound roof roadway.
