The structure of the tailings dump in the technological chain of a mining enterprise is functionally designed for storage of ore processing waste and clarification of technical water in the recycling water supply system of the mineral processing plant. In most cases, a tailings dump is an aggradation facility, the capacity of which is provided by the protective structures called tailings dams. The author analyses functional features of construction and operation of tailings in a technological chain of the mining e...

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 ...

The geo fluid mechanical model of the natural and technical system "the store-the protecting construction-the geological basis" which in the program PLAXIS complex has been realized in a computer 3D model has been developed for a research and assessment of reliability of the store of liquid industrial wastes. For each component of model it was set, taking into account basic data, the corresponding mechanism of deformation: elastic-plastic, elastic and viscous-plastic, filtration consolidation. As the changing infl...

Authors examined particularities in shelf oil and gas production. Social-economic aspects have been revealed of consequences during underwater production and pipeline transportation of hydrocarbon crude. Volumes of losses from emergencies at pipelines and platforms were analyzed with differentiation of principal world shelf oil and gas production regions. Loss volumes were estimated for the North-Eastern European region with reference to components of hydrocarbon production and transportation systems. Methodical a...
