This article presents an analysis of the stability of stopes that is based on the mathematical modelling of stress-strain states and the criterial assessment of destruction of the heterogeneous layered rock mass encompassing a system of mine openings. The problem solution has been carried out in the plane strain state setting. The state of an undermined stratum has been described by an ideal elastic-plastic medium. The technological interbed and the roof of an upper bed have been modeled by a layered medium includ...

This article considers the methodical provisions of geomechanical analysis of a change in the stress-strain state of the undermined saliferous mass over time. The mathematical modeling of deformation and destruction of the water-blocking strata (WBS) has been carried out in the elastic-plastic setting for plane-strain conditions (PS). The safe conditions of undermining of the water-blocking strata (WBS) have been assessed and the geomechanical justification of used additional protective measures has been made in t...
