The method of forecasting of occurrence of possible technogenic earthquakes, depending on the subsidence of the earth's surface, the volume of rocks that are removed and displaced and the intensity of geological disturbances, is developed. The state of disturbed and technogenic environments in the conditions of their water saturation, loading, introduction of organic materials is modeled in the laboratory conditions. It has been proved that the rate of water saturation varies significantly for different types of man-made raw material and depends on its granulometric composition. The mineralization of quarry waters with depth, depending on the physical and chemical composition of the enclosing rocks, is investigated. It is shown that in the quarry waters there is an increase in mineralization due to the contact of underground waters with the surrounding rocks. Based on this, it is suggested to capture groundwater before entering the quarry to reduce their mineralization and energy expended on their demineralization. The simulation modeling of the direction of operation of the excited environment with the placement of man-made massif is carried out. At the same time the stability of the formed technogenic array is influenced by the geometric forms of the embankment, the number of layers, water saturation, mineralogical composition, external influence. Theoretical researches of creation of multi-gradient load of a rock at the initial stage of expansion of a charging cavity are carried out. A methodology was developed and experimental researches on the nature of the destruction of sand-cement models with prolonged explosive charges, providing multi-gradient load. The scientific significance of the work lies in the established dependencies of the state of the disturbed and man-made massifs from the influence of water saturation, organic matter, and the displacement of large volumes of rock mass within the region, which allows predicting these changes and effectively used to maintain the operational state of such objects. The practical significance of the results obtained is that the theoretical and laboratory results allowed to develop practical recommendations for choosing the rational parameters of the internal dump and the methodology for calculating the technological indicators of dehydration and sieve used by the enterprises in the projects and modernization of production. Scientific and practical results allow to predict the changes in the properties and parameters of technogenic and disturbed mediums, calculate ecological and technological risks. Research Methods: field observations, laboratory and pilot tests, mathematical and computer modeling, technical and economic analysis. Materials R & D are designed for use in mining company and design organizations of Ukraine. Product Description popup.authors Єфремов Е.І. Ікол О.О. Іщенко К.С. Бабій К.В. Бубнова О.А.
