Sažetak
The stability analysis of large-scale rock slopes in heterogeneous and discontinuous rock masses still presents one of the main problems in rock and mining engineering today. The case study of large-scale slope stability analysis in heterogeneous and discontinuous rock masses in the St. Juraj - St. Kajo open pit mine has been compiled. The geological formation of this site consists of flysch sediments which have layers with extremely different properties and unfavourable disposition in relation to slope configuration. This may result in forming the slip surface of composite shape. In order to obtain an appropriate solution for slope stability, limit equilibrium and numerical modelling methods of different computer programs have been used. The evaluation of physically acceptable solution is presented on the basis of calculation method and its obtained results for critical slip surface
