Abstract

Mining of ore deposits in conditions of increased mining pressure is often associated with dangerous stress concentrations that can cause harmful consequences for production: deformation of workings and separate sections of the ore body, crushing of pillars, self-collapse of ore and other phenomena that increase the danger of work, losses of minerals, labor and cost.
