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...

In this paper, the principle of constructing an adaptive biomechanical model of the spine is described, which allows modeling damage to the spinal segments, spinal cord and nerve roots, as well as taking into account the perception and tolerability of pain. Adaptability of this model is achieved due to the possibility of introducing individual parameters of a particular segment (geometric dimensions and spatial coordinates of the elements (vertebra, intervertebral disc, nerve roots, spinal canal); modulus of elast...

In this article, the stages of creating three-dimensional geomechanical models in the development of deposits by open method are considered in detail, based on the results of calculating the safety factor of the open pit sides. The geomechanical model consists of four main components - geological, structural, hydrogeological models and rock mass model. The models are based on the geological, hydrogeological, geotechnical data of the field. Such geomechanical models allow to optimize the work of the whole enterpris...

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...
