露天煤矿顺层边坡变形失稳控制对策研究与实践
Study and Practice of Control Countermeasure for Deformation and Instability of Bedding Slope in Surface Coal Mine
摘要
Abstract
Down-dip strata is one of the important factors that influence slope stability,which has long troubled the safe production of surface coal mine.When there are weak rock formations in the slope,slope stability will be more serious.Taking the deformation and instability control project of the south side slope of Antaibao Surface Coal Mine in Pingshuo Mining Area as an example,the methods of numerical analysis,limit equilibrium analysis and deformation monitoring are adopted in this paper,and the feasibility of deformation failure mode and the control measure of internal dumping and presser foot for bedding slope containing weak strata is studied,and the engineering applicability verification analysis is carried out.The results of research and practice show that the internal dumping and presser foot method has the characteristics of low cost and quick effect,which has obvious applicability to control the slope stability of surface coal mine.关键词
