В настоящее время в экономическом развитии не только отдельных регионов, но и всей страны особую роль играет состояние добывающей промышленности, в основном топливно-энергетических ресурсов и цветных металлов. В Российской Федерации доходы, получаемые за счет добычи и экспорта минерального сырья, в стоимостном выражении составляют около 80% российского экспорта. В статье рассматриваются экономические аспекты недропользования в северных регионах ресурсного типа, специализирующихся на добыче высоколиквидных минеральных ресурсов: нефти, газа, угля, алмазов и золота с целью выявления сильных и слабых сторон. Анализируются минерально-сырьевой и производственный потенциалы добывающей промышленности регионов. Методом математической статистики оценивается уровень зависимости социального развития регионов от добывающей промышленности по шкале Чеддока. На основе факторного анализа и оценки экономических составляющих недропользования и региональной статистики за 2010-2020 гг. выявлены высокий уровень ресурсной ориентированности экономики, капиталоемкости и фондоемкости добывающей промышленности и моноспециализация экономики во всех северных регионах ресурсного типа, высокий уровень зависимости социального развития от добывающей промышленности в Республике Саха (Якутия), Ханты-Мансийском – Югра и Ямало-Ненецком автономном округах. Выделены негативные и позитивные факторы устойчивого развития добывающей промышленности, также определены ключевые моменты перспективного развития экономики северных регионов ресурсного типа. At present, the state of the mining industry, mainly fuel and energy resources and non-ferrous metals, plays a special role in the economic development of not only individual regions, but also the whole country. In the Russian Federation, revenues derived from the extraction and export of mineral raw materials in value terms account for about 80% of Russian exports. The article discusses the economic aspects of subsurface use in the northern resource-type regions specializing in the extraction of highly liquid mineral resources: oil, gas, coal, diamonds and gold in order to identify strengths and weaknesses. The mineral raw materials and production potentials of the mining industry of the regions are analyzed. The method of mathematical statistics evaluates the level of dependence of the social development of regions on the extractive industry on the Cheddock scale. Based on a factor analysis and assessment of the economic components of subsurface use and regional statistics for 2010-2020, there was revealed a high level of resource orientation of the economy; capital intensity of the mining industry and monospecialization of the economy in all northern resource-type regions; a high level of dependence of social development on the extractive industry in the Sakha Republic (Yakutia), Khanty-Mansiysk-Yugra and Yamalo-Nenets Autonomous Okrugs. The negative and positive factors of the sustainable development of the mining industry are highlighted, and the key points of the prospective development of the economy of the northern regions of the resource type are also identified.

Abstract In the article it is proved, that the economic development of any industry depends on the results of the economic activities of the enterprises that are part of it. Based on the available statistical data, we proposed a model for diagnosing the results of the mining industry and conducted a comparative analysis of the results of the study in the context of economic activities. Given the high integration of mining enterprises into the system of intersectoral relations, this problem cannot be solved within the framework of one industry. Therefore, it is proved that, taking into account the existing experience, it requires complex measures: accounts receivable are formed as a result of late payment for delivered products. The main consumers of the extractive industry are: the processing industry, the supply of electricity, gas, air conditioning and transport. They consume more than 87% of the products of this industry in the intermediate consumption market and are the most debtors; on the other hand, these regions are also the largest suppliers of raw materials, materials and semi-finished products for the extractive industry. Therefore, in the end, the accumulation of current accounts payable at the enterprises of the extractive industry for the delivered goods and services is the least desirable for them.

This paper presents the results of the research aimed at the creation of the ilmenite-fluorite welding flux using mineral raw materials of the Far Eastern region. The authors have performed thermodynamic calculation based analysis of the possible physical and chemical processes in the slag system. The experimental research we have conducted resulted in the mathematical dependencies that allow selecting flux components that would ensure the desired properties of the hard facing surfaces formed. Experimental overlay welding sessions were performed to determine the welding-technological characteristics and properties of the welded deposit. The results of the research show that the flux, consisting of 50 % of the mineral components extracted in the Far Eastern region and of 50 % of the standard flux АN22 is basic (В = 1.46) and has a low oxygenation capacity (А = 0.22). This facilitates reduction processes in the slag bath and, as a consequence of, results in obtaining high quality weld deposit. High level mechanical and performance properties of the coatings formed is maintained due to the reduction of alloying elements and possible formation of carbides (CrFe)7C3 or (CrFe)23C6, alloyed cementite (CrFe)7C3 and other substances. As an example, overlay welding under AN22PK-DMS flux produces the maximum content of chrome in the welded deposit of 12 – 15 %, and the maximum content of manganese of 6 %.

Contemporary mining industry is a complex system that is constantly expanding both in terms of explored sources of mineral raw materials and in terms of developing new approaches to mining and processing of minerals. Such a buildup in the scope of tasks set for the industry, as well as the technical progress, lead to various issues related to the quality, quantity and rational use of mineral raw materials. Rationalization, in its turn, should be carried out in a phased manner through the use of comprehensive measures, one of which is reclamation of man-made wastes, represented by waste rocks, tailings, slags, dust, etc. In addition, this approach simultaneously resolves several other important challenges the industry is facing, e.g. increasing the environmental safety of mining regions and increasing the economic feasibility of production by extracting additional components from waste materials. The scope of application of such a solution to the challenge of rationalizing production is immense and can be implemented at many deposits located in the territory of the CIS due to the presence of huge volumes of waste generated by mining raw materials. These wastes were accumulated because of the absence of full-fledged technologies to extract useful components from the rock mass in the past as well as other requirements to ore conditioning than those acting today. For example, in the Republic of Bashkortostan, the overburden dumps and off-balance ores that have been created by mining enterprises amount to more than 1 billion tons, hydraulic-mine dumps of processing plants reach 50 million tons, manmade waters exceed 9 million m3 annually. At the same time, the amount of useful components contained in these man-made deposits can be up to 1.5 million tons for copper, 2 million tons for zinc, about 100 tons of gold as well as significant amounts of other associated components, including various non-metallic formations.

The Impact

The level of development has been considered, the impact of mining industry on the world economy and its connections with other spheres of the world economy have been analyzed. Today mining industry is not only one of the leading fields of global economy, but it has also promoted the emergence of other fundamental branches. The development of this sphere is extremely important not only for the state, which plays the role of a regulator, but also for investors, contractors, suppliers, service companies, indigenous population and consumers. Due to its long-term development, mining industry differs from the majority of other kinds of human activity. Diversified mining industry is generally a prerogative of highly developed countries since only several segments are often functioning in less developed countries, and sometimes mineral raw materials are only extracted there. Nowadays no country in the world possesses full range of all types of rocks and minerals. Basic tendencies in development of extraction of mineral raw materials in different countries have been described. The current state of global mining industry can be called the advent of the so-called new era due to the increase of cost of mineral raw materials; however it is also necessary to develop the fields even with quite small and low-quality mineral reserves. Mining operations and development of mineral deposits are being relocated from the developed countries to the developing ones. It is better to consider the possibility of improvement of already existing objects instead of building brand new ones for more efficient and easier operation of mining companies. Problems of functioning and obstacles of development of mining enterprises in Ukraine under current conditions have been determined, ways of their elimination and increase of effectiveness in the branch in general have been proposed. National mining industry is adversely affected by such external factors as the global financial and economic crisis, processes of globalization. Although the mineral-raw material base of Ukraine has a sufficient amount of explored reserves of most mineral resources, it is currently at the stage of depletion of the subsoil, which requires the reformation of the economic mechanism for its use.

The analysis of macroeconomic indicators of the results of solid mineral extraction (TPI) in 11 subjects of the Far Eastern Federal district (DFO) was performed. The total value of production of all types of minerals (DPI) in terms of money at DFO is about 2.4 trillion rubles (45% of total gross regional product (GRP) of the region is equal to 5 trillion rubles.). More than 63% of the volume of DPI is achieved at the expense of fuel and energy resources of the Sakhalin region and the Republic of Sakha (Yakutia). In the dynamics of the region, there is a significant increase in GRP, production and value added for the DPI in general, and the production of fuel and energy minerals, but slower growth in the production of solid minerals. Ore (metal) raw materials of the region’s subjects in its total GRP is about 21%, in value terms-500 billion rubles. The region produces 16-18 types of ore mineral raw materials, including 12 types of raw materials as the main components of production, 4-5 types-as associated components. The main one is gold production (in 2019 more than 170 tons), silver (more than 930 tons). In the Far Eastern Federal district, reserves and resources of the main TPI for the long term have been identified. It is possible to significantly support the mining industry of the region in the case of exploration of new deposits with high-quality ores. Ore mineral raw materials of the leading geological and industrial types are currently insufficiently studied. It is necessary to develop intra-regional use and processing of raw materials to final products, create metallurgical industries, this will give new incentives to the development of the region’s resources. The analysis is of practical importance for evaluating and selecting directions in the deposits of subsurface use.

The Stability

Relevance. The efficiency of using the products of subsoil exploitation is a factor in strengthening the mineral resource base of the mining industry. The success of improving ore preparation technologies is associated with the activation of mineral raw materials in mills, including impact mills – disintegrators. A fundamentally new approach to ore processing technology includes a combination of grinding methods in mills and other activators. The issues of increasing the activity of substances on the basis of combination form an urgent scientific and industrial problem. The aim of the study of the phenomenon of combined activation is to search for the possibility of increasing the level of activation, to ensure the stability of the acquired activity and to establish patterns of relationships between the activation processes and the technological processes of using mineral raw materials. Objects: products of the development of deposits of solid mineral raw materials in various mining sectors of the national economy. Methods: Laboratory, semi-industrial and industrial experiment using improved equipment for the activation of mineral raw materials. Results. The concepts of “mechanical activation” in mills and “activation with large mechanical energy” in a disintegrator are detailed. An assessment is given to the directions of improving the mills. The results of mechanochemical activation of powders oxides in a planetary centrifugal mill “Aktivator-2s” are given. The practice of activating mineral raw materials with a combination of activators of various types is described. It has been established that the efficiency of combining mills depends on the initial size of the crushed material and equipment options are recommended depending on this. It is shown that the combination of drum and vibration mills reduced the energy consumption of the product. The results of the combination and the vibrating mill in the technological chain of the concrete complex are presented. The algorithm for the combined activation of mineral raw materials is illustrated by the example of the technology applied at the mine, which includes grinding, mixing binders, inert aggregates and grout, as well as transporting the concrete mixture to the place of use. As a quantitative indicator of activation, an equivalent of activity or a proportional ratio of the combined components is proposed. The efficiency of using solid mineral raw materials increases when it is prepared in activators.

The purpose of the article is using the data of Geoinform of Ukraine on the current state of the mineral resource base of the country, to regionalize its territory by combining explored mineral deposits and production-territorial complexes formed on their basis with a mineral raw material orientation. Research results. The article is written in the context of the constructive-geographical direction of studying the geography of mineral resources, which has been developing in the last decades in Ukraine. In particular, three approaches to regionalization of territorial combinations of mineral deposits are compared and analyzed: geological, economic-geographical and mining, which will contribute to their interconnection in characterizing the mineral-raw materials complexes of individual regions. The authors’ own interpretations of discussion definitions of mining terminology are proposed. Based on the results of previous studies and taking into account the current state of the mineral resource base, economic-geographical and mining zoning of the territory of Ukraine has been carried out for groups of explored mineral deposits. Within Ukraine, four mineral resource zones are allocated: Prydniprovsko-Pryazovska, Eastern Ukrainian, Donetsko-Slovianska and Prykarpatska, as well as several territorially separate structures: Zakarpatskyi, Lvivsko-Volynskyi, Podilskyi, Kerchenskyi, Krymskyi macrodistricts, Zhytomyrskyi and Pobuzkyi districts. A detailed description of the mineral and raw material specifications of these structures and their constituent parts, the features and prospects of their exploitation, the formation of territorial-production complexes of mineral and raw materials orientation are submitted. Scientific novelty. For the first time, various approaches to the regionalization of territorial groupings of mineral deposits and mining territories are compared, the basic definitions of mining regionalization are presented, and on this basis their own variant of zoning the territory of Ukraine on mineral resources is proposed. Practical value. The economic, geographical and mining zoning of the territory of Ukraine according to the forms of concentration of mineral deposits and mining areas will help create the scientific basis for optimizing the structure of the mining industry, ensuring the effective use of mineral raw materials, and developing the country's raw material complex.

The purpose of the article is to identify the spatial character of foreign investment in Siberia where a considerable part of Russian export goods is produced for the markets of Europe and the Asia-Pacific region. A microeconomic approach was used, and the types and activities of enterprises with foreign capital were analysed. The main features were presented: the predominance of offshore investments, officially identified as foreign investment in the basic industries; increase in the share of investment into the mining industry and increasing dependence on China when moving east; high level of individual’s investment in services with fast capital turnover and minimal capital costs which forms a specific survival environment in the border areas with Mongolia and China. Three patterns of foreign investment in the Siberia are identified – western, central and eastern. The western pattern is characterised by a diversity of donor countries and investment in processing industries, the central one is based on the offshore capital in energy and semi-product industries, and in the eastern pattern investment into mining and logging prevails. The last type of investment is not receptive to innovations and new technologies, conserves and deepens the resource specialisation of industry for Asian markets of raw materials.
