Abstract
Factors which influence the formation of the stress condition of ore body and the intensity of failure of stopes are investigated for Yakovlev’s mine conditions. Calculations of depth of failure zones in stopes are made. Method of failure prevention is developed. It allows to increase the safety of mining and technical and economic index.
