Abstract

Result of research is definition the zone of influence of sewage treatment works and their character for developing nearbord stocks Koashva opencast. The analysis of changes in the stress-strain state of massif around development workings in stages mining substages depending on their position relative to cleaning area. The research was carried out using a numerical modelling using the finite elements method.
