Vitushko O. The development of scientific foundation of mining mechanics of buried hydroengineering systems

The subjects of inquiry are processes of rocks deflected mode repartition, filtrational flow of electrolytic solutions and polydisperse mineral hydrotransportation in buried hydroengineering systems. The purpose of the work is development of scientific foundation of mining mechanics of buried hydroengineering systems by accounting of regularities of electrolytic solutions flow in porous massif, stationary and non-stationary hydrotransportation for rising of profitability and mining operational safety including mining under conditions of geological irregularities. Methods of investigations. The modern methods of scientific investigations were used for solution of raised problems, namely methods of rocks mechanics, methods of multiphase media hydrodynamics for non-stationary processes of slurries flow analysis, methods of capillary hydrodynamics for processes of electrolytes flow analysis taking into account features of processes taking place on interphase, methods of probability theory and mathematical statistics when solving classification and statistical modelling problems. The information and methodical assurance of calculation of parameters of geohydromechanical processes in buried hydroengineering systems was first elaborated, which had allowed to receive an annual expected affordability at the rate of 183,00 thousand hrn. due to application of the methods of calculation of electrolytic solutions filtration in massif, expected affordability during 10 years at the rate of 124,78 million hrn. due to application of the methods of calculation of hydrotransport plants parameters and real annual affordability at the rate of 324,07 thousand hrn. due to application of scientific results in conditions of the "Olhovaya-Zapadnaya" mine.
