摘要
Abstract
In order to study the feasibility of the increasing and expanding internal dump of Yimin Open-pit Mine,the slope stability of the internal dump should be studied quantitatively.By mean of engineering geological exploration,the article obtains spatial distribution of strata and establishes the typical engineering geological profile model.The typical engineering geological profile model is recalibrated according to the physical logging results;by using the physical logging results,the rock soil physical mechanical tests and the strength reduction formula,the recommended physical mechanics index values of rock soil are determined comprehensively;we use the finite difference software to study the deformation failure mode.The results show that the potential deformation failure mode of the whole internal dump slope is"circular shear bedding slip"mode,The stability of internal the whole internal dump slope is be in steady state,the stability factor meets the requirements of the code for design of open-pit mine of coal industry.关键词
