Abstract

The development of a progressive technology for workings based on the determination of the stress-strain state (SSS) of the massif and its influence on the parameters of fastening and subsequent maintenance is an important scientific and technical task of mining. In the process of research, the SSS was determined around the mine working: roof, soil and sides; strain rate, delamination zone (crack formation); stresses (compression, tension, shear), displacement from service life (in dynamics). Relatively favorable, medium and difficult conditions for the operation of mine workings, the influence of mining-geological and mining-technical factors on the formation of inelastic deformation zones in the host rocks around the workings were considered. Studies were carried out on the stability of the contours of development workings, taking into account their stress-strain state, depending on mining and geological factors; stress-strain state of excavation workings depending on the influence of technological factors using the finite element method. The boundaries of the region of inelastic deformations were determined by the method of successive loadings.
