Grigor'ev, V. Kovalenko, S. Usmanov] Conclusions: The engineering method of determining limiting slope angles in deep quarries, which is presented in this paper, can be the basis of an ADS for quarry faces. The method accomplishes the following: slope stability is evaluated on the basis of analysis of the field of elastoplastic stresses with allowance for the geometry and geologic structure of the mass and the properties of the continuum; the process of the formation of the finite-element grid is automated; optimizing renumbering of the nodes is performed; a minimum volume of on-line memory is used to solve the system of equations; the geomechanical models realized in the method describe rather accurately the behavior of the mass under the force of gravity; the software makes it possible to accept different mathematical theories of strength; and, the results of the computations are presented in graphic form; this increases the information that can be gleaned from them. Analysis of the results of numerical modeling of the stress-strain state of a rock mass and field observations exposed the following laws: a face is stable if the zone of plasticity is local; in this case, the iteration process is convergent; a face is unstable if the zone of plasticity increases continuously and if the region of tensile stresses and the iteration process are divergent.
