| 摘 要： | 安家岭露天矿随着采场自西向东推进,内排土场即将跨过破碎站,当+1330以上内排台阶推进到破碎站后,需要在破碎站以东留设运输主出入沟,运输主出入沟的留设需要占用很大的内排空间,特别是沟道的北帮为内排帮,存在时间长,要求稳定程度高。文中对影响边坡稳定性的因素进行了分析,并采用FLAC3D数值模拟软件对边坡的变形进行了数值模拟,揭示了内排边坡的变形规律及滑坡模式。

| Abstract: | Combination of Anjialing surface mine actual situation,With the advance of stope from west to East,inner dump coming across the crushing station,when more than+1330 within the row level advance to the crushing station,need to stay transportation main access channel east of the crushing station,transportation main access channel setting large occupancy of the inner row space,especially the ditch north side is the inner discharge slope,existing for a long time,requiring a high degree of stability.In this paper,the influence factors of slope stability are analyzed,and FLAC3D numerical simulation software on the slope deformation was simulated,reveals the inner dump slope deformation law and landslide model. |
