Abstract
The article presents the mining and geological characteristics of the Mountain Shoriya rockburst-hazardous deposits. The experience of measuring the stress state of the rock mass at the Tashtagol and Sheregesh iron ore deposits and the results of the refinement of current stresses are presented. Stresses in the rock mass are determined to select the type of support for workings while lowering the level of mining.
