I. Kosukhin, D. V. Sidorov, V. Yu. Timofeev // IOP Conference Series: Materials Science and Engineering. — Bristol : IOP Publishing, 2019. — Vol. 582 : Innovative Technologies in Engineering : X International Scientific and Practical Conference, 23–25 May 2019, Yurga, Russian Federation : [proceedings]. — [012018, 9 p.].
Abstract: The publication describes the problem of transcendental deformation mode of interchamber pillar and ore deposit associated with the formation of hazardous zones in the rock mass in process of development of rockburst-hazardous rock masses at the great depth. Geomechanical software PRESS 3D URAL is used to assess the impact of the range of geological and technological factors on the mode of interchamber pillars deformation and ore deposit. The software allows to solve spatial problems in the elastic-plastic formulation. The results of step-by-step modeling of different mining and technical situations with a test of the bearing capacity of interchamber pillars showed that some of them can't withstand the mountain pressure and go to the transcendental mode of deformation with subsequent destruction. Identification of the destroyed pillars allows to adjust the boundary conditions of loading the ore mass. At the same time the neglect of transcendental mode of deformation of interchamber pillars can lead to an undervaluation of the stress level in the ore mass by 1.5 or more times. This can lead to an error in predicting the parameters of zones dangerous due to rock bumps.
