摘要: 针对朱家包包矿西南帮边坡滑落失稳等问题,采用理论分析、现场监测等研究手段,对该矿西南帮1 180 m至1 270 m段高进行监测与分析。研究表明:边坡失稳产生了楔形体破坏,确定滑体稳定类型为可能滑动;失稳对采场安全生产带来严重隐患,通过扩帮清理1 180 m水平以上全部滑体,同时采用锚杆、锚索+肋柱挡板支护方式的治理方案,解除了滑体对采场安全生产的威胁,并恢复了1 270 m公路通车。

Abstract: Aiming at instability and landsliding of the southwest slope in Zhujiabaobao mine, slopes at the height of 1180 m to 1 270 m were monitored and analyzed by means of theoretical analysis and field monitoring. The study showed that the slope instability caused wedge-shaped failure, and the stabilization type of the sliding body was determined as possible sliding; The instability brings serious hidden trouble to the safety production of the stope, and all the sliding bodies above the level of 1 180 m were cleaned up by expanding the slope. At the same time, the support scheme of bolt, anchor cable and rib baffle was adopted to relieve the safety threat of the sliding body to the stope, and the 1270 m highway reopened to traffic.

Key words: Slope instability, Wedge failure, Monitoring, Stability analysis, Slope expanding and cleaning
