Stability Analysis And Evaluation Of High Rock Slopes Of Luishia Mine

At present, with the development and utilization of mineral resources, rail and highway construction, deep foundation pit excavation and the exploitation of the deep open pit mine, accordingly, construction of the project encountered problems of rock slope stability of the corresponding is increaseing. Especially for the problem of those large open pit slopes in particular.As the ore body restrictive conditions, increasing the depth of open mining, slope height gradually increased, eventually the formation of depression or furrow stope stope, while mining production conditions are getting worse, open-air rock slope difficulty to maintain stability and the probability of failure of stope growing, production and life to mine the enormous damage and economic losses. Open pit mine slope design, the final determination of slope angle, slope stability analysis and evaluation, slope reinforcement governance is increasingly important, so that open pit rock slope stability problem is a specialized research topic.This thesis Luishia detailed exploration data mining based on the formation of the future mining area of high rock slope stability for qualitative and quantitative evaluation, and determine the final mining point of view, the process proposed mining Slope treatment measures. By laboratory experiments, rock parameters to the analysis, slope stability evaluation of rock mass structure, limit equilibrium slope stability analysis and finite element method, the excavation process of the stress, deformation and stability of the carried out study. Based on the findings, using a certain criterion or graphical visualization methods to determine the slope of the sliding surface, then using rigid body limit equilibrium method or the elastic-plastic finite element quantitative evaluation of its safety and stability, eventually determined that the open pit mining stable slope angle.
