Abstract

Approaches to selection of technological mining schemes based on selective potash seam extraction are described. Progressive technological mining schemes for potash mining company «Belaruskaliy» and the geological conditions of the IV potash horizon are reviewed. Basic aspects of the geomechanical substantiation of parameters of technological mining schemes for conditions of the new potash horizon in the presence of influence of the overlying horizons are also presented. Guidelines for substantiation of progressive mining methods for the conditions of the IV potash horizon (Third Mine, «Belaruskaliy») are developed on the basis of the modeling of the stress-and-strain state of the rocks.
