摘　　要：陕南秦岭矿产资源开采区地质环境脆弱,加之受到采矿工程活动的影响,区内地质灾害频发。以"秦岭及宁东矿产资源集中开采区地质环境调查"项目为依据,通过遥感解译、无人机航拍及野外实地调查,对陕南钒矿开采区斜坡灾害的发育特征及失稳模式进行了较为详细的调研。基于调查结果,将区内斜坡灾害归纳为滑移-压致拉裂、滑移-剪切-拉裂与弯曲-倾倒三种典型的失稳破坏模式,并对每种模式进行了实例分析。同时,结合斜坡灾害失稳模式及分布规律,探讨了坡形、坡向、坡度、岩性、岩层倾角、岩体结构、降雨及采矿等因子对斜坡稳定性的影响,并提出了各因子的影响程度区间。在此基础上,综合考虑各类影响因素,提出了针对性的防控对策。The geological environment is fragile in South Shaanxi mining area, and combine with the mining engineering activities, geological hazards are much more easier to take place in this area. Based on the project Geological Environment Survey of Qinling and Ningdong Mineral Resources , we carry out a more detailed research on the development characteristics and instability types of slope hazards in South Shaanxi Vanadium mining area, through remote sensing interpretation, drones pictures and geological field survey. According to the results, three failure types of the slope are concluded and analyzed in detail. At the same time, eight impact factors of slope hazard are studied in further and their dominance is obtained. Then, a set of related countermeasures are proposed as well.
