Annotation:
Modelling of the slope stability for the open-cast №7 “Pivden” of the Malyshevske placer deposit of titanium-zirconium ore at the Vilnoghirsk Mining and Metallurgical Plant by the finite element software Phase2 is carried out. The safety factors for open-cast slopes depending on complex geological structure and watering rock massif by Mohr-Coulomb failure criterion are determined.
