URANIUM DEPOSITS «DISAGREEMENT» OF CANADIAN AND AUSTRALIAN SHIELDS
The geological and structural features and conditions of localization of deposits in Canada and Australia are considered, conclusions are made about the genetic difference between objects that affect the methodology for their identification. A comparative analysis of the deposits was carried out and their main features were identified in order to increase the effectiveness of the search for analogues in Russia. The source of evidence was the publication of foreign and domestic researchers.
Keywords: uranium deposits, structural-stratigraphic disagreements (SSN), localization conditions and morphology of ores, structural control of mineralization, hydrothermal rock changes, mineral and material composition of ores, tectonomagmatic activation (TMA).

THE NEW TYPE URANIUM-GOLD DEPOSITS IN LINEAR CRUSR WETHERING ON OLDER SHIELDS FOR EXSAMPLE SEVERNOE DEPOSIT (ALDAN SHIELD, REPUBLIC SAKHA (YAKUTIA))
The poor U-Au mineralization established over initial ore bodies in deposits of Elkon District. New complex technological method heap leaching of Au and U worked out for this mineralization. Two technology sorts of ores revealed in Severnoe deposit: Au-Ag and Au-Ag with increased content of uranium. Au and Ag extracted from both sorts of method cyaniding. The uranium leaching weak sulfuric acid solution. The ore mining of open-pit and processing of heap leaching development of these deposits will create the new large-scale region.
Keywords: Ehlkon, Severnoe, gold, uranium, technological sorts, heap leaching (HL).

CHEMICAL DIRECTION IN MINERALOGY AND VASILY MIKHAILOVICH SEVERGIN
The article is devoted to the scientific activity of the Russian mineralogist and chemist, academician of the Imperial Russian Academy of Sciences (since 1793) V.M. Severgin – one of the founders of the chemical field in mineralogy. His work was very progressive and mainly devoted to mineralogy, inorganic chemistry, metallurgy. First formulated (1798) the concept of paragenesis («adjacency of minerals»). In scientific activity, the successor of M.V. Lomonosov, seeing in the study of mineral communities not only a way to elucidate the conditions for the formation of minerals, but also the basis for scientific search forecasts.
Keywords: V.M. Severgin, chemical field, mineralogy, chemistry, mineral waters, mineralogy of natural waters.

DEWATERING WELLS’ EXPLOITATION IN THE DEVELOPING OF THE DIAMOND PIPES OF THE MINE BY M.V. LOMONOSOV
In the article, according to the observation data of the drain circuit exploitation made around the quarries of the south group of pipes of the mine by M.V. Lomonosov, there were introduced many facts indicating the influence of the suffusion processes to the condition of the exploiting dewatering well. On the base of the given data of the condition DWW and theoretical investigations, the authors provide the physical model of the suffusion cavities at the filtered zones of the exploiting wells of the drain circuit where it is possible to get the mechanism of the soil’s collapse in the overlapping deposits with the following violation of the integrity of the filter column which happened, for example, at DWW 32. Under the different conditions of the integrity of the filter column, distribution of cavities along the filter column and position of the grave sprinkle in the annulus of the well, it is given in the article the practical recommendation of the preparation of DWW to the following exploitation.
Keywords: drain circuit, dewatering wells, suffusion processes, deposit, grave sprinkle, filter zone.

ON THE MODES OF OCCURRENCE OF URANIUM IN THE HYDROZIRCONE
Examples of the study of patterns of distribution and modes of occurrence of uranium in uranium bearing metacolloidal hidrozircon localized in sedimentary rocks of the Cretaceous Severocesky plate, it was found that the uranium mineral is in two forms – isomorphic in the form of microinclusions own mineral phases.
Keywords: uran, hidrozircon, electronmicroscopy, microinclusions, coffinite, microdiffraction.

MODERNIZATION OF CUTTERS CUTTING OF TUNNELING MACHINE
Currently, the excavation by TBM, a huge role is played by the rate of production (ROP). The speed is largely influenced by the cutters cutting, namely their stopsenate and speed of replacement. The paper offers modernization of cutters cutting of tunneling machine to easily replaceable cutters. Shows how to install, replace, consolidate modernized cutters. The aim of this work is to find and use the option of cut of the cutters, which allow to reduce the cost of tunnelling works and will speed up the process of sinking.
Keywords: tunneling shield, cutter.

ASSESSMENT OF MINERAL RESOURCE POTENTIAL OF RESERVES AND FORECAST RESOURCES DURING THE LIFE CYCLE OF EXPLORATION PRODUCTS
The author’s approach to the assessment of mineral resources (investment) potential of both reserves and forecast resources during the life cycle of exploration products is considered. The method is based on the valuation of reserves and forecast resources using transfer coefficients as integral indicators. As a result, the assessment of mineral resources potential of reserves and forecast resources of the Central Federal district by geological and economic zones was carried out, the key directions of development of mineral resources potential were determined.
Keywords: mineral resource base, mineral resource potential, geo-economic monitoring, mineral asset, investment attractiveness, life cycle, exploration products.

LANDSLIDE PROCESSES OF THE LOWER REACHES OF THE SURA RIVER
We considered the features of the landslide process in the lower reaches of the Sura river. We made a map of engineering-geological conditions of a landslide slope with elements of geomorphological taxa within the projected railway. We calculated a stability of a slope by various methods. Keywords: slope, landslide, sliding surface, groundwater.
