主　　题：elastic mechanics oval-shaped furrow pit slope stability limit equilibrium angle ratio of stripping-to-ore 

摘      要：The space effects of oval-shaped furrow pit slopes were analyzed by the elastic mechanics *** interaction of limit equilibrium slope angle,friction coefficient,cohesion and horizontal radius of oval-shaped furrow pits has been *** oval trumpet-like rock mass is homogeneous and elastic while only loaded by its dead *** interaction indicates that the deeper an oval-shaped furrow pit is excavated,the greater the limit equilibrium slope *** the theory base for reducing stripping waste rock in an oval-shaped furrow pit and the basic way to determine the configuration of a stable slope were developed from the mentioned *** theory includes the preceding principles of stability analysis of *** with the configuration determined by traditional theory of slope stability,a great quantity of stripping waste rock can be reduced by that determined in this paper under stable conditions.
