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 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.

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.

The Impact

The article is devoted to the issue of the possibility of economic development of the mining industry in the subjects of the Far Eastern Federal District (FEFD) and the impact of investment projects. With the vast wealth and diversity of mineral resources, their involvement in the national economy is an essential factor in the industrialization and successful development of the regions. In the case of the establishment of processing plants, for a number of minerals, the region could provide its own needs, as well as the countries, finished products from it, and develop an export focus. The article considers the export orientation of the mineral and raw materials complex of Russia and the constituent entities of the Russian Federation, as well as the commodity structure of exports of the regions of the FEFD. Special attention is paid to the implementation of major regional investment projects, which are important for the development of the regions. So, it is proposed to implement a major project in the form of an integrated mining and metallurgical complex due to the fact that the region needs its own ferrous metallurgy. The calculations carried out (in various versions: basic, in the conditions of the territory of advanced development (TAD), without the costs of infrastructure creation) showed that the implementation of the project is cost-effective, but due to the high costs, the support of the state is necessary.

The paper examines environmental problems of a city with a developed mining industry. Their influence on social stability, public health and demography, labor activity, migration, etc. was revealed. The methodology for assessing social and ecological tension for the city of Sibay in the Republic of Bashkortostan was tested, based on the approaches developed by I.A. Sosunova for the regions of Russia. The main materials for calculating the socio-ecological tension of the city were data from the analysis of information on the socio-economic and ecological state of the territory, conducting a sociological survey of the population, as well as assessing the ecological and geochemical state of the environment by a set of ecological indicators. All indicators were assessed using five-point scales. The final indicator was the index of social and ecological tension, which was determined by dividing the sum of points for the indicators under consideration by their number. As a result of a comprehensive analysis, it was revealed that the socio-ecological tension of the city of Sibay includes: Gorny (3,7) Yuzhny (3,2) Center (2,7) Gold (2,6) Eastern (2,4) Fishermans House (2,3) Arkaim (1,6). The use of the category of socio-ecological tension in the proposed interpretation makes it possible to identify sociological problems of behavior and society. The results of the study are recommended to be used for a comprehensive analysis of indicators for monitoring urbanized territories of a mining region, which determine its environmental safety and sustainable development, ranking the territory as well as a set of economically justified measures to include them in the programs of strategic development of the region.
