Abstract: Mine slope stability evaluation is one of the most current topics in geotechnical engineering. A mine slope in Tianyang County, Guangxi Province was selected as a case study in this paper. Based on the analysis of the failure mode of the slope, slope stability was evaluated using limit equilibrium, numerical modeling and stereographic projection approaches. Three methods from different prospective were used to evaluate the same problem to ensure reliability of the mine stability prediction. This case study can also provide an example for stability evaluations of similar mine slopes in Southwest China.
