Abstract: A comprehensive assessment on rock slope stability was carried out by combining the key block theory with the fuzzy method. Based on typical slope of strip mine in Fushun, the physical and mechanical parameters were measured and a block identification system—GeoSMA-3D (Geotechnical Structure and Model Analysis-3D) was developed to identify the key blocks and to calculate the factors of safety. The assessment factors were detemined based on the characteristics of the spatial blocks. According to the information acquired, a fuzzy comprehensive assessment method based on AHP was applied to assess the stability of the slopes in an objective and quantitative way. Finally, an visualizaion plantform is established to visulize the terrain and total safety factors of the slope, which provides a reliable basis for disaster control and reinforcement on the slopes.

Key words: strip mine, rock slope, analytic hierarchy process, block theory, fuzzy evaluation
