DEVELOPMENT OF 3D GEOMECHANICAL MODELS FOR UNDERGROUND MINES AND OPEN PITS

Abstract

This article describes the stages of creating three-dimensional geomechanical models in developing of deposits by underground and open methods, based on the results of calculating the safety factor of the open pit sides and stability ratings of underground mines. The geomechanical model consists of four main components - geological, structural, hydrogeological models and rock mass model. The models are based on the geological, hydrogeological, and geotechnical data of the deposit, such geomechanical models allow to optimize the work of the whole enterprise, correctly assess the risks, scientifically
justify the parameters of field development. The creation of geomechanical models includes several stages: the collection and processing of data, the analysis of the obtained results, the transferring of graphic documentation into digital one, and the
working with digital data in specialized GIS.
