Based on experimental studies of destruction dynamic loads polymineral rocks in their processing surfactants , found: in rocks containing quartz, changes the nature of the destruction at the macro level . It is associated with the formation of new surfaces by contact of quartz grains with other rock-forming minerals .. Samples of these rocks , which are not treated with surfactants , the new formed fracture surfaces are formed mainly by defects vnutrishnozernovym structure of quartz. As the strength of the material , due to the action of surfactants , increasing the average diameter of pieces of rocks destroyed. On the basis of the laws of elasticity theory analytically investigated conditions for determining the effect of stress on natural resilience indicators rock mechanical destruction for the purpose of performance management tools porodoruynivnyh . Done mathematical modeling of unsteady filtration and geomechanical processes taking place in the gas-saturated rock mass in mine corrosion of concrete structures , the flow of gas dynamic phenomena, fluid injection into coal seams. A set of design methodologies . The model guided the creation of man-made deposits on the basis of the existing tailings storage of minerals. These models allow through knowledge of the mineralogical and grain size of waste stored, and the laws of motion of individual particles in the flow pulpovodi and pulp, choose the method of manufacture of pulp and alluvium slime storages , divided by the material content of useful components and thus form a promising area for industrial mineral extraction. Implementation of waste disposal of controlled formation of technogenic deposits will reduce the area engaged during slime storages , increase resource base of enterprises as a whole will have a positive economic, environmental and social impact. Research methods : in situ observations and laboratory tests, mathematical and computer modeling, feasibility and mining- geometric analysis. Materials research for use in mining and project organizations in Ukraine. Product Description popup.authors Єфремов Е.І. Ікол О.О. Іщенко К.С. Бабій К.В. Баранов В.А. Бубнова О.А. Васильєв Д.Л.
