Petrological classification of properties of complexes of rocks formed in different geological conditions are elaborated. The fundamentals of the theory of control energy transfer explosives for destroys rocks, in which have been further developed views on the mechanism of their destruction in the explosive phase of the wave action, are developed. Guidelines for substantiation of rational parameters of drilling and blasting under explosive loading of fissured anisotropic rock for the conditions of nonmetallic quarries of Ukraine are developed. Numerical simulation of gasdynamic processes in the face of mine development working in its holding around tectonic faults and taking into account factors such as technology of development and the depth of penetration in the outburst zone are performed. Computational methods for the study of non-stationary physical and technological processes in the gas-saturated rock mass, which occur as one by one so and simultaneously, are elaborated. The technique of experimental studies of the effect of stress in the surface area of the face in the development on indicators of resistance of rocks to mechanical destruction in laboratory and mine conditions are developed. A program for computers and numerical studies performed stress distribution in the natural rock mass stress to determine their effect on resistance to mechanical failure in the area of production of slaughter are made. The theory of compliance of natural processes lithogenesis on processes of formation of technogenic arrays are elaborated on based on the identified regularities of natural and man-caused processes in the sludge collector. The models of controlled formation of technogenic deposits and method of creating technogenic reservoir in mining and mining enterprises tailings pond are made. The technology of recultivation with the restoration hydraulic connection of aquifers are developed . Materials research are intended for use by mining companies and design organizations of Ukraine.
