Determination of impact hazard potential of rocks in the Norilsk Industrial Region
The deeper the mineral deposits developments are, the worse the mining and geological conditions become. Significant growth of stress level in the rock mass contributes to possible manifestation of rock pressure in dynamic form. The resulting task of assessment of rock impact hazard is closely related to the task of obtaining more accurate results of compression tests of samples in rigid or servohydraulic test presses using graphs of their full deformation. This approach requires special expensive equipment, considerable time resources, and sufficient core material. Therefore, it is important to have an approach that allows to assess the propensity of rocks to brittle fracture with research methods simple enough not to result in the loss of quality and reliability of the obtained results. This paper presents the results of laboratory tests of rocks from the Norilsk Industrial Region to determine their tensile and compressive strengths. Test methods involved both domestic and foreign standards for determining the value of the brittleness coefficient. The impact hazard potential of rocks was determined using the Kaiser criterion. It is found that the tested lithological types (rich sulfide ores, hornblende, disseminated ores, and gabbro-dolerite rocks), with the exception of anhydrite, have a low impact hazard potential.

The polyphase Belokurikhinsky granite massif, Gorny Altai: isotope-geochemical study of zircon
Based on the isotopic-geochemical analyses of zircons from granites of the Belokurikhinsky massif in the Gorny Altai using the U-Pb method, the ages of three intrusion phases have been determined for the first time: the age of the first phase refers to the time interval of 255-250 Ma, the second and the third phases have similar ages of about 250 Ma. The formation time of the Belokurikhinsky massif is estimated as not exceeding 5-8 Ma. The δ18O values for zircons from granites of the second and the third intrusion phases average around 11.5-12.0 ‰, indicating a significant contribution of a crustal component in the formation of the parent melts for granites of these phases. The crystallization temperature values of the zircons by the Ti-in-zircon thermometer for three phases range from 820 to 800 °C. The P-T crystallization parameters of titanite from the first phase, determined using a titanite thermobarometer, average around 770 °C and 2.7 kbar. The zircons from the first phase mostly exhibits geochemical characteristics of typical magmatic zircons. The zircons from the second and the third intrusion phases either may be unaltered magmatic zircons or enriched in incompatible elements (LREE, Th, U, Ti, Ca, etc.) due to fluid influence, resembling hydrothermal-metasomatic type zircons in terms of their geochemical characteristics. A number of zircon grains from the second and the third phases of granites demonstrate anomalous geochemical characteristics – the REE distribution spectra atypical for zircons (including “bird's wing” type spectra with oppositely tilted of light and heavy REE distribution profiles), as well as significantly higher contents of certain trace elements compared to other varieties. Such an enriched zircon composition and wide variations in the incompatible element content are due to non-equilibrium conditions of zircon crystallization and evolution of the fluid-saturated melt composition during the final stages of the massif formation.

Influence of mining rent on the efficiency of using natural potential: the paradox of plenty and its Russian specifics
- Authors:
- Arunas A. Lapinskas
The most powerful potential of Russia's natural resources is only partially realized, and determining the reasons for the insufficient efficiency of its use is a current research topic. The exploitation of mineral resources that bring mining rent (primarily oil and gas) gives rise to the so-called “paradox of plenty” (PP), which in some cases manifests itself as a significant slowdown in economic development. The purpose of the article is to clarify the signs, degree and forms of PP manifestation and related problems (“resource curse”, “oil curse”, etc.) in the Russian economy. Since the causes of these phenomena are usually associated with rent extraction and peculiarities of the institutional structure of the economy, the works of leading economists who support the theories of “rent-oriented behavior” and the role of public institutions in the process of the PP emergence were critically analyzed. To determine the signs and degree of PP manifestation and related problems, an analysis of determining the shares of oil and gas in the structure of exports, revenues from their sale in the federal budget, and oil and gas products in the structure of GDP, was made. It is concluded that there are no sufficient grounds for ascertaining clear signs of a “rent-oriented” Russian economy and a “resource curse”; important counteracting factors that refute the unambiguous conclusions about the high degree of PP impact on the Russian economy were identified. The author's interpretation of the role of public institutions, the factors of formation and forms of PP manifestation, the specifics of differential mining rent and its role in the formation of PP are proposed; options for solving problems generated by PP – directions for improving the tax system in the field of oil and gas, etc.; substantiation of the need to develop a strategic state program for diversifying the sectoral structure of the Russian economy; directions for adjusting economic policy in the field of oil and gas industry development, etc.

Integrated mining projects in underdeveloped territories of Russia: substantiation of implementation parameters
- Authors:
- T. V. Ponomarenko
- E. A. Khan-Tsai
- Ch. Bavuu
Complex mining projects, as a rule, have significant economic and social impact on the territory, sometimes entire regions where they are implemented. Consumers of their implementation effects are population, government, buyers, lenders and other stakeholders. Therefore, development of transport infrastructure in integrated projects for development of mineral deposits should have state support, forms of which are very diverse. In Russia parameters of concession agreements for construction of transport infrastructure, carried out in conjunction with projects for development of mineral deposits, are not regulated or justified. Aim of the work is to develop an organizational model and justify parameters of concession agreement for construction of the railway as a key element of transport infrastructure necessary for successful implementation of the project for development of a large coal deposit in a low-developed region. Research methods are: strategic, institutional, investment analysis, modeling and forecasting methods. The article proposes an approach to justification of technical, economic and financial parameters of concession agreement implemented during realization of an integrated mining project. As a result of the study, a concession agreement model was developed for construction of railway section as part of an integrated mining project, including development of a deposit and construction of a mining and concentrating company.

A Modern View of Anomalies in the Metal Groups of the Periodic System of D.I.Mendeleev
The article is devoted to the 150 th anniversary of the Periodic Table of Chemical Elements by D.I.Mendeleev. The fundamental law of nature, discovered by D.I.Mendeleev has anomalies and paradoxes associated with certain groups of metals. When studying the physical and chemical properties of complex metal compounds, many discrepancies can be found, namely, the location of elements in groups, which primarily relate to metals with different valences. By studying the approaches and methods for predicting the arrangement of chemical elements, it can be established that D.I.Mendeleev eliminated many differences for some metals during the formation of the Periodic system of chemical elements. D.I.Mendeleev developed a principle that excludes such errors when finding and discovering new elements. Analytical studies conducted by a Russian scientist helped to calculate the atomic masses and describe the properties of three elements not known at that time – «eka-boron», «eka-silicon», «eka-aluminum», the existence of which was proved and confirmed by subsequent discoveries of scandium, germanium, boron, and gallium. The paper provides a significant assessment of the forecasting of metals in various groups of the periodic system. Changes in the properties of some metals significantly influenced their location in the table of D.I.Mendeleev.

Assessment of Rock-Burst Hazard in Deep Layer Mining at Nikolayevskoye Field
The paper presents results of conducted research using regional and local methods of forecast and control over geomechanical state of the rock mass at burst-hazardous Nikolayevskoye field, located in a geodynamically active region. The study subject is the ore mass of Nikolayevskoye field, characterized by man-induced and tectonic disturbances and high geodynamic activity. The aim of research was practical implementation of methods and instruments of forecast and control over geomechanical state of the burst-hazardous rock mass and safety improvement of mining operations. Exploitation practice of burst-hazardous fields demonstrates that forecast accuracy of hazardous rock pressure demands cutting-edge multi-level systems, where local methods and tools complement regional ones. A regional forecast of rock-burst hazard at Nikolayevskoye field was performed by means of seismoacoustic method using automated control system for rock pressure (ACSRP) «Prognoz-АDS». Local forecast was carried out using «Prognoz-L» device, geophysical (sample disking) method and visual observations of dynamic pressure manifestations in the mining tunnels. Quality assessment of stress-strain and burst state of the rock mass was performed using specialized software «PRESS 3D URAL». Integration of engineering and geomechanical data in the process of conducting research guarantees a relevant assessment of rock-burst hazard in various areas of the field at various stages of its development. Practical verification of the system, where local methods and tools complement regional ones, demonstrated satisfactory results at Nikolayevskoye mining plant, which makes it recommendable for other mining facilities extracting ore at great depths under similar conditions of active geodynamic processes.
