The natural-and-technical system composed of a dump and its foundation possesses certain parameters, physical and mechanical properties and shear resistance, and experiences the external impacts and loads in the form of active shearing forces and the internal counter reaction. Using the experimental data on 20 external dumps after their deformation by means of shearing along the dump and its foundation interface, the model of the natural-and-technical system (NTS) of the dump and its foundation is built. The model is given an algorithm for estimating the weight of influence exerted by the impacts and loads on the stress–strain behavior of the dump–foundation NTS. For the design stability factor and the test characteristics (physical and mechanical properties of dump, shear resistance of foundation, hydrostatic pressure, earthquake-induced seismicity), the regression equations are obtained as an inverse polynomial relation (2nd order) with the close correlation ( > 0.7) of the stability factor with the hydrodynamic pressure D and seismic loads Q; as well as the direct linear relation is found between the stability factor and the internal counter reaction forces with the high correlation factor (r ≈ 1.0). The increments of arguments of the test characteristics, such that deviation of the stability factor is below a limiting value, are determined.
