Аннотация: This paper presents the results of determining the physical and mechanical properties of rocks of The gorevsky GOK quarry massif. For this purpose, a complex of geological exploration and laboratory tests was performed, which included drilling eight inclined geomechanical wells with a length of 300 to 630 m, followed by testing of Показать полностьюthe core material. The results of the stability factor calculation for different angles of inclination and heights of the design side of the Gorevsky GOK quarry along the profile of each geomechanical well are presented. Recommended design parameters of stable slopes of the sides, taking into account the curvilinear shape of the quarry in the plan. It is concluded that when calculating the stable parameters of the pit sides, it is possible to increase the stable slope angle with a reserve factor of 1.0 by 5, which will reduce the volume of overburden operations while maintaining the stability of the Gorevsky GOK massif.
