The results of modeling and estimation based on the finite element method, of propagation boundaries of horizontal deformations with due account of structural features of rock mass, and also strength and deformational properties of various lithological differences composing the open-pit slope are represented.

The technique of ore reclaiming process flowsheets with stationary both semiportable crushers and classifying points parameters definition is presented. The best results of ore reclaiming are obtained by unloading ore to the loading bunker from several working faces.
