Abstract
Regularities of forming of strained – deformed state in elements of designed variants of systems of development on various mining stages for Nikolaevskoe and Yuzhnoe polymetallic deposits are determined on the results of numerical modeling. Analysis of technogeneous stress field made it possible to discover some potential burst-hazardous sections of the rock massif and to substantiate effective rock pressure decreasing measures for preventing dynamic rock pressure occurrences.
