摘　　要：贵州山区采动斜坡变形失稳灾害频繁,且崩滑灾害具有规模大、破坏性强、破坏模式复杂等特点。因此,充分掌握采动作用下山区斜坡变形特征,不仅能更好地揭示斜坡的失稳机理,也能对其稳定性作出正确的评价。本研究以贵州省织金县文家坝矿区崩塌体为研究对象,在现场详细勘查的基础上,根据斜坡危岩带发育情况和变形破坏特征,对局部危岩和堆积体开展稳定性分析,探讨地下采动作用对斜坡稳定性的影响,最后采用RocFall软件模拟了危岩体运动模式与影响范围,提出了“被动防护网+局部危岩清理+监测”的工程防治措施,可为矿区采动斜坡变形破坏机制和稳定性分析提供借鉴。The deformation and instability disasters of mining slopes in the mountainous area of Guizhou occur frequently,and the landslide disasters are characterized by large scale,strong destructiveness,and complex failure modes.Therefore,fully grasping the deformation characteristics of mountain slopes under mining action can not only better reveal the instability mechanism of the slopes,but also make a correct evaluation of their stability.Taking the collapse body of the Wenjiaba mining area in Zhijin County,Guizhou Province as the research object,based on detailed field investigations,and in accordance with the development,deformation,and failure characteristics of the unstable rock zone of the slope,the stability analysis of the local unstable rock and accumulation body is carried out to explore the influence of underground mining action on slope stability is discussed.Finally,the RocFall software is utilized to simulate the movement mode and influence range of the unstable rock mass,and the engineering prevention and control measures of“passive protection network+local unstable rock cleaning+monitoring”are proposed.The results of the study can provide a reference for the deformation and failure mechanism and stability analysis of the mining slope in mining areas.
