摘　　要：抚顺西露天矿南帮发生大面积滑移变形,致使坑底变形区内煤炭停止开采。通过实施回填压脚、防治水等综合治理方案,边坡变形速率数据变化趋于平稳。为充分回收煤炭资源,采取优化措施调整开采方法,对区内煤炭进行条带式开采即分区开采、随采随填,最后进行南北平铺式回填,为南帮边坡稳定提供了有力保障。The south slope emerges large sliding deformation in West Open-pit Mine, which results in stopping coal mining in the pit deformation zone. Through the implementation of backfilling presser foot, prevention and control of water comprehensive control scheme, the data change of slope deformation rate is stable. For full recovery of coal resources, the mine adopts optimization measures to adjust mining method, and carries out partition mining and strip mining and north and south backfill, which provides powerful guarantee for the stability of south slope.
