The numerical, theoretical, and experimental values were significantly different from the results shown in Tables 3 and 4. However, as presented in Figure 11, a significant correlation was found between the numerical values at cutting speeds of 1 m/s and the other study values since a cutting speed of 1 m/s is closer to real excavation values.

Using combined FEM/DEMDFN (discrete fracture network) modeling, it was possible to investigate the formation of a basal failure surface within an open pit slope as a direct result of cave mining. The modeling of Palabora highlighted the importance of rock mass tensile strength and its influence on cavinginduced slope response.

Highlights We model delayed behaviour of an excavation in the context of geological nuclear waste storage. Modelling is performed with hydromechanical coupling and regularization. The constitutive law for the rock mass is an elastoviscoplastic one called LK. Comparisons of water pressures and displacements with in situ measures validate simulations.
