Modelling of mining constructions stability by the means of rock strength reduction

Abstract

The purpose of the purpose is to improve the approach to the assessment of different stability of slopes, having overcome such a lack of the existing approach as the uncertainty of purpose of the displacement line. The authors of the paper developed a technique of the creation of difficult space objects, such as pits, dumps of breeds on the surfaces containing breeds and ore bodies, breeds of breaks, with the use of spline approximation with their subsequent introduction in the ANSYS computer system. The space model for the geomechanical assessment of the condition of breeds in and in the neighborhood of a pit is offered. The model allows to count the parameters of the intense deformed state of the massif, to remove necessary results in external files and further to use for the analysis of stability both a pit board in general, and its separate elements. The obtained data will allow to define the danger area of the deformation processes development in the career. That gives the opportunity to advance the implementation of necessary actions for ensuring the boards stability.
