安太堡露天矿复杂地质边坡滑坡灾害防治对策与实践
Countermeasures and practices for prevention and control of landslide disasters on complex geological slopes of Antaibao Open-pit Mine
摘要
Abstract
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.关键词
