Talykova THE CONTRIBUTION OF MAN-MADE AND NATURAL SOURCES OF IONIZING RADIATION TO MORBIDITY STRUCTURE OF MURMANSK REGION The contribution of man-made and natural sources of ionizing radiation into the morbidity structure of the Murmansk region is demonstrated. Significant correlations were found between the average annual effective dose of radionuclides fallen in the northern hemisphere due to atmospheric testing of nuclear weapon and indices of infant and perinatal mortality; stillbirth and congenital malformations (CM) of children. A link was also revealed between the dynamics of the CM and the noble gases emissions at Kola atomic power plant as well as with Cosmic rays intensity variations. Prevalence rates of tuberculosis and cancer for adults occurred to be correlated with variations of cosmic rays. Contamination of the Arctic by radionuclides of man-made origin is a major cause of the morbidity increase for local population. Natural sources of ionizing radiation can modulate sensitivity of humans to exposure of the man-made sources of radiation. Keywords: Ionizing radiation, natural and man-made sources, cosmic rays, Be-7, radon, atmosphere, impact to morbidity, Murmansk region. V.P. Petrov, L.S. Petrovskaya, M.N. Petrovsky, M.G. Tymopheeva HIGH-CALCIUM SILICA-ALUMINA GNEISSES IN CENTRAL KOLA BLOCK: GEOLOGICAL AND METAMORPHIC ORIGIN Geological-petrological and petrogeochemical properties are described for high-calcium silica-alumina gneisses of the Kola series in the Central Kola Block of the Kola peninsula, which are featured with specific chemical and mineral composition compared to “classical” gneisses of the Kola series. Petrochemical data analysis and peculiarities of microelements distribution within the rock mass are used to ground a reconstruction of the protolyte composition and origin as well as geodynamical situations during their forming. Keywords: Central Kola Block, high-calcium gneiss, metamorphism, Р-Т conditions, age, reconstruction, protolyte, geodynamical situations. G.Yu. Ivanyuk, A.O. Kalashnikov, V.A. Sokharev, Ya.A.

Goryainov THREE-DIMEHSIONAL MINERALOGICAL MODEL OF THE KOVDOR MAGNETITE-APATITE- BADDELEYITE DEPOSIT A three-dimensional mineralogical model of the Kovdor magnetite-apatite-baddeleyite deposit is presented. The deposit includes concentrically zoned phoscorite-carbonatite pipe that is intruded through eastern contact of alcaline and ultrabasic rocks of the Kovdor massif. Petrographic zoning of the pipe is reflected in the composition and properties of ore minerals, which cause vertical zoning of the pipe and must be considered for optimization of ore extraction and processing.

Lukchev DEEP MINING - NEW TECHNOLOGIES Current state of mining industry is characterized by the trend towards rapid development of deep mining thus resulting in increased production costs of mineral extraction and having negative impact on safety of mining works. It is possible to decrease open-pit mining costs due to pit wall steeping following the fulfillment of a set of conditions whose neglecting can lead to serious consequences such as fatalities, machinery destruction, shutdown or decline in plant capacity. The calculation problem of pit wall and slope face optimum angle has become difficult due to required consideration of rock mass structure and its stress state as well as slope stability impacted by seasonal precipitation. This kind of problem has been solved for the Kovdorsky GOK. To provide this solution, the following measures were taken: geological-structural mapping of the deposit, pit wall design with double bench and vertical slope angles, development of smooth blasting, pit wall state and near contour rock mass 122
