This paper proposes the modeling of the contact dynamics as a nonsmooth discrete element method (NSCD). The theoretical basis of a new approach which makes it possible to consider a better surface contact with friction between polyhedric discrete elements simultaneously is studied. The results of the application of the NSCD to investigate the verified examples present the stability conditions of jointed rock slopes. The rock mass is first geometrically represented through the distribution of discontinuities in the rock mass and the use of the LMGC90 code based on the discrete fracture network (DFN) method. The 3D computational models are analysed by using the LMGC90 based on the NSCD method. The application of the methodology of numerical simulation of multi-phase excavation of rock slope cut is provided. A case study of the data was performed on the benches of a limestone clues quarry situated in the south of France. The mechanical responses of the numerical rock mass are analysed and evaluated
