安太堡露天矿复杂地质边坡滑坡灾害防治对策与实践OA
Countermeasures and practices for prevention and control of landslide disasters on complex geological slopes of Antaibao Open-pit Mine
为快速解决露天矿端帮在顺倾弱层、褶皱和地下水等不良地质因素耦合影响下的边坡变形稳定问题,以安太堡露天矿东帮北部区域复杂地质边坡为例,在边坡稳定影响因素和裂缝成因分析的基础上,构建变形区域边坡典型工程地质模型,采用数值分析和极限平衡分析相结合的方法研究了边坡的变形失稳规律及其防治对策.结果表明,特殊的地质条件和采矿条件对东帮北部区域边坡稳定不利,边坡宏观破坏模式为坐落式平推滑移破坏,微观地质力学模式为滑移(蠕滑)-拉裂型破坏,针对性地提出了"削坡回填+变形监测+坡表截排水+巡视检查"相结合的露天矿端帮滑坡灾害综合防控方法.
In order to quickly solve the problem of slope deformation and stability of the end slope in open-pit mine under the coupling influence of unfavorable geological factors such as bedding weak layer,fold and groundwater,taking the complex geological slope in the northern region of the eastern slope of Antaibao Open-pit Mine as an example,the article constructes a typical engineering geological model of slope in deformation area based on the analysis of slope stability influencing factors and crack formation causes,studies the deformation and instability law of slope and its prevention and control countermeasures by combining numerical analysis and limit equilibrium analysis.The results show that the special geological and mining conditions are unfavorable to the slope stability in the northern region of the eastern slope.The macroscopic failure mode of the slope is the seated push-slip failure,and the micro-geomechanical mode is slip(creep)-tensile failure.We present landslide disaster comprehensive prevention and control method of combining with"cut slope and fill back+deformation monitoring+surface drainage+patrol inspection"at the end slope of open-pit mine.
