monitoring system. Geomechanic state of the rock mass is of great importance for providing safety and stability of an underground mine’ work. Comprehensive solution of the safety problem is in transition to minimally-manned operation and to unmanned production techniques in the future. Accepting such technologies is future-proof not only in terms of miners’ safety but also in reduction of the costs related to comfortable and safe working conditions. Fully autonomous LHD machinery is already used in the mines of LKAB (Sweden) and Inca (Canada) as well as El Teniente (Chile) and Jundee (Australia). Over the last years technological process automation during open-pit mining is actively developed. Keywords: mining, open-pit mine, underground mine, pit wall, slope angle, berm, overburden ratio, stress-strained state, rock burst, mining-induced earthquake, minimally-manned operation, remote control, autonomous transport.

Gromov THE STU DY OF THE MECHANISM OF PHOSPHORIC ACID EXTRACTION BY ONE ATOMIC ALIPHATIC ALCOHOLS USING THE METHOD OF IR SPECTROSCOPY Using the method of IR spectroscopy, there has been examined the mechanism of phosphoric acid extraction with the one-atomic aliphatic alcohols, namely n-pentanol, n-octanol, iso-octanol, and n-decanol. All the IR spectra o f extracts have revealed bands o f hydroxonium ion H3O+ and ether groups P-O-Alk. It has been concluded that the process of phosphoric acid extraction can perform by two mechanisms: either hydrate-solvate or chemical interaction. A correlation between the quantity of water passed to the extract at different CH3PO4and the acid distribution coefficient has been observed. Keywords: phosphoric acid, aliphatic alcohols, extraction mechanism, IR spectroscopy. V.G. Kremenetsky, S.A. Kuznetsov QUANTUM-CHEMICAL STUDY OF THE STABLE COMPLEX PARTICLES COMPOSITION IN ALKALI METAL HALIDE MELTS The main goal o f the work is in quantum-chemical prove o f existence the stable complex species formed by the transition metal halide complex and outer-sphere shell of the certain composition in alkali metal halide melts. The novelty of the approach used in this study is the direct calculation of the interaction energies of the second coordination sphere fragments with both the chromium complex itself and the outside environment of this fragment. As an example, the extended model systems M3CrCl6+18MCl(M - Na, K) are used, for which the optimized structures and energies are obtained by quantum-chemical methods. Based on these data and additional calculations related to fragments of these systems, it was concluded that the stable particles "complex with outer-sphere shell" are formed in such systems. Keywords: chromium chloride complex, DFT calculations, stable particles in melts, fragments interaction energy. T.A. Kornilova, I.A. Kornilov GROUND BASED AND THEMIS OBSERVATIONS OF 24.01.2012 CME EVENT On the base of auroral white light TV observations at Lovozero, Barentsburg and Canadian Themis ASI data magnetospheric and auroral effects o f 24.01.2012 strong CME (Coronal Mass Ejection) event were investigated. It is very important that magnetosphere was very quiet during more then 8 hours before CME event, so effect of CME interaction with magnetosphere can be studied without masking effects. Comparison of fine details of aurora dynamics with Themis satellites data on magnetic and electric fields and particle fluxes in energy range 10 eV - 500 keV allowed making preliminary conclusions concerning auroral electrons source localization and acceleration mechanism. Specifically, it was found that auroral activity at Lovozero leaded strong Barentsburg aurora for about 7 minutes. Keywords: coronal mass ejection, solar wind, magnetosphere, aurora. D.G. Ishkulov, A.L. Mikhailyuk, M.V. Pakhomov FEATURES OF COLOR VISION IN GREY SEAL One of the most effective methods to protect offshore and near-shore facilities and infrastructure is using biotechnical marine mammal systems, i.e. systems that combine marine animals, human personnel, and technical equipment. Among other marine mammals, grey seals are of great potential to be used as a key functional biologic element of these animal/human systems. In order to develop new methods of training marine mammal capabilities to operate against unauthorized swimmers and SCUBA divers, to find, mark the location and salvage objects resting on the sea floor or drifting in the water, one needs knowledge on perception of colors by the seals. Scientific publications on the color vision of common seals are scarce, fragmentary, and mostly theoretic. Data on the color perception in grey seal are almost unavailable. 123
