Abstract

This paper deals with the deformation mechanisms and stability analysis of large slopes. The Sarcheshmeh mine west wall was selected as a case study. The current height of Sarcheshmeh west wall is 450 m, and in the future planning, pit depth exceeds over 800 m. With regard to the high future west wall (up to 1000 m), a comprehensive stability analysis was conducted. A sophisticated 3D model of the west wall was constructed and a comprehensive stress analysis was conducted. Both current and future slope geometries were analyzed, and the slope deformation mechanisms and stress change history were investigated as a function of slope excavation. The effect of regional in situ stress regime on the wall stability was demonstrated. Numerical modeling results are in agreement with field observations and predict instabilities for the midsection of Sarcheshmeh west wall.
