摘要
针对F3断层切割平庄西露天矿西北帮边坡形成三维滑体,采用二维计算方法已经不能满足计算要求,因此采用3Dslope边坡计算软件对西北帮边坡进行稳定性计算.结果表明:通过分析西北帮边坡的影响因素,确定潜在滑坡模式,计算由F3断层和弱层以及假设的侧滑面控制的三维滑体边坡稳定系数.从而确定滑体的大小,控制F3断层影响范围,采取相应的治理措施,该成果为安全生产提供技术支持.
In Pingzhuang West open pit,the F3 fault cuts the northwest pit slope and forms a 3-D sliding mass.The 2-D calculation method cannot meet the requirements of mine safety and production.Therefore,the 3Dslope software is adopted to model the stability of the northwest pit slope.After analyzing the factors affecting the northwest pit slope,and defining the potential landslide pattern,the stability coefficient of the 3-D pit slope controlled by F3 fault,the weak layers and the hypothetic sideslip is obtained.Therefore,the size of the sliding mass and the influence range of F3 fault can be determined,and the proper control measures can be taken.The study provides some technical supports to mine safe production,and a significant theoretical and practical reference.
