A computer hydrogeomechanical 3D model of a fragment of a soil tailing dam has been developed. The model allows investigating both geo mechanical and filtration processes and also their collateral influence on a condition of soils of the bulk protecting dam and the alluvial beach of the tailing. The following options of development of a hydrogeomechanical condition of a soil dam have been considered: an initial state at the current operation parameters, increase in level of water-saturated mining deposits and the subsequent consolidation of bulk and alluvial soils within 1, 2, 3, 5, 10, 15, 20, 30, 50 and 80 days. The PLAXIS software has performed the 4D modelling (taking into account a time factor) of consolidation of soils of a dam and alluvial deposits by the corresponding options. The received results were analyzed on dynamics of a dam?s hydrogeomechanical condition, as a result, there were revealed trends of its time history. It has been established that the consolidation nature of bulk and alluvial soils is identical, but quantitatively significantly differs. Dependences of consolidation of bulk and alluvial dam soils and the tailing on consolidation time have been established that provides a scientific and technical basis for assessment of a mechanical state and stability of a dam, and for engineering actions for industrial safety of its operation
