Sažetak
The stability of an open pit mine with large-scale rock slopes still presents one of the main problems in rock and mining engineering today. The main cause of this is the presence of discontinuities which have a pivotal role for stability. Because of discontinuities the failure of large-scale rock slopes may involve the combination of several different failure mechanisms in which the slip surface of complex shape is formed. A numerical research in developing the estimation method, which enables calculation of the stability factor of rock slopes for complex shape of slip surfaces, has been undertaken. The setting up and searching procedure of critical slip surface of complex shape is very different in this method than in the other ones. The analysed example shows the successfulness in determining the critical slip surface as well as the calculation factor of stability for the complex shape of slip surface.
