The purpose of the study is to develop scientific bases and improve methods and means to increase the efficiency and safety of mining operations at enterprises with targeted and associated uranium ore mining. Research methods: mechanics of rock destruction, mathematical physics and mechanics of a continuous medium, nonlinear oscillations of mechanical systems, theories of elasticity and viscoelasticity, thermodynamics, woodworking, decryptography, electron and optical microscopy, X-ray diffraction analysis, chemical analysis methods. For the first time the main factors influencing safety increase at storage of radioactive waste of uranium ores are established; the analysis of geomechanical factors of the massif of rocks and methods of their forecast by acoustic and electromagnetic methods is carried out the analysis of efficiency of existing technological decisions on safety of conducting mining works at extraction of uranium ores is carried out; geomechanical factors influencing the safety and productivity of miners are identified; the analysis of the factors promoting increase of productivity of functioning of vibrating mining feeders is carried out; the factors restraining increase of productivity of output from ducts of uranium ores by vibrating feeders and fine classification on size and dehydration of the crushed uranium ores and wastes of their processing in processes of enrichment and utilization are established. The novelty of the work is the substantiation of the criteria for comparing the factors that lead to increased safety in the preservation of radioactive waste of uranium ores and the productivity of work to search for radioactive raw materials in Ukraine. The implementation of the results of the work will help increase the economic efficiency of uranium mining enterprises in Ukraine. Product Description popup.authors Efremov Ernest I.
