Abstract

Development of advanced technology developments on the basis of determining the stress – strain state (SSS) of the array and its influence on the parameters of the fixtures and the subsequent maintenance, is an important scientific and technical challenge of mining. During the study determined VAT around excavation: roofs, soil and sides; Rotational deformation zone bundles (cracking); stress (compression, tension, shear), offset from the lifetime (in dynamics) were considered relatively favorable, average and complex operating conditions of mine workings. Addressing the impact of mining and geological factors on the formation of zones of inelastic deformation in the country rocks around the excavation workings. Conducted investigating the stability contours of development workings in accordance with their stress-strain state depending on mining – geological factors ; stress-strain state of excavation workings depending on the impact of technological factors, using the finite element method. Were defined boundary of inelastic deformation by successive loading
