Abstract
The article presents calculation methodology for evaluating both the technical conditions of the VS-3 mine shaft and the state of rock mass at the Oktyabr’sky mine for the purpose of providing for the safety of mining operations while under-mining rich ores. The proposed method serves as a basis for quantitative and qualitative analysis of the rock mass stress-strain state in the developed areas and inferences about appropriate protective measures for mine workings.
