| 中文摘要: |
| 金属露天矿山高陡顺倾边坡易形成大规模变形体或大型滑坡，防治难度大，是矿山安全高效生产的重大隐患。本文通过系统开展滇西北衙金多金属矿区万硐山矿段露天采场顺层边坡稳定性分析实例，研究了不同计算方法和不同工况下该类边坡滑坡失稳条件，采用数值模拟计算分析相结合的方法得出其滑坡类型及失稳模式，并提出了这类结构的露天矿山边坡风险管控措施建议，为矿山后续开采提供依据，指导矿山实际生产。 |
| 英文摘要: |
| The high and steep inclined slope of metal open-pit mine is easy to form large-scale deformation or large-scale landslide， which is difficult to prevent and control， and is a major hidden danger for safe and efficient production of mine. Through the systematic analysis of the stability of the strata slope in the open pit of a certain mining area in Wantongshan section， the landslide instability conditions of this kind of slope under different calculation methods and different working conditions are studied. The landslide type and instability mode are obtained by combining numerical simulation calculation and analysis， and the risk control measures of the open pit slope with this structure are proposed. It provides the basis for the subsequent mining and guides the actual production of the mine. |
