Abstract
The paper presents the results of assessing the slope stability of benches at the actual and design pit outlines of the Gorevskoye lead-zinc deposit. Based on analyzing a 3D model of the open pit and elements of weakening surface occurrence in the near-wall rock mass, the calculation models of possible deformation were selected, which were used for kinematic stability analysis. Areas which mining method geometric parameters fail to meet the caving probability criterion have been identified for the limiting pit outline of the ore deposit, hence, the parameters of the mining method have been adjusted when they are applied to the limiting position.
