Аннотация: The article studies influence of slide rocks on the bottom of Internatsionalny open pit mine on stress state of rock mass during stoping under the pit bottom. The stress distribution during extraction of ore reserves from the initial layer under the pit bottom is determined. The post-limiting deformation zones in ore body during foПоказать полностьюrmation of a crown pillar are delineated using the Mohr-Coulomb criterion. The authors give a predictive estimate of alteration in stress state of the crown pillar with the advance of stoping.
