Abstract
To assess the stability of mine workings, the mechanism of deformation, displacement and collapse of rocks in a structurally disturbed heterogeneous massif is investigated. Technological conditions are developed for stabilizing the soil of working, taking into account the state of the rock mass. The parameters of roof bolting ensuring the safety and efficiency of mine operations are obtained.
