This study aims to identify the groups of closely spaced mineral deposits located in the Southern East Siberia and to describe these clusters. The mineral resource base of this region includes the deposits of lead, zinc, tungsten, tin, molybdenum, uranium, copper, gold, lithium, tantalum, niobium, silver, fluorite, zirconium, rare-earth metals, iron, mica, precious and semi-precious stones, oil, gas, and coal. Many of these deposits contain a significant part of the explored mineral reserves of Russia. The deposits are located in the tectonic structures of the Siberian platform (Tunguska syncline, Nepa arch, Cheremkhovo and Priangarie depressions), as well as in the fold belts framing the platform from the south and southeast (Baikal-Patom, Dzhida-Vitim, etc.). These structures and belts formed under the influence of plate tectonic and plume tectonic processes. This article describes the clusters of mineral deposits of the Angara, Sayan, Baikal and Transbaikalia regions. Currently, the most developed are the clusters located in the southern part of the study area (Shilka, Argun, Yeravnino, etc.). In the northern part (Mama-Bodaibo, etc.), the clusters have been either partially developed within the existing mining areas or are at the initial stage of development. In these territories, the road infrastructure, power supply and other facilities required for mining industry are either underdeveloped or lacking. Prospects for the regional development are related to the economic development of the territories adjacent to the Baikal-Amur railroad (BAM) and hydrocarbons production in the zone near the East Siberia – Far East oil pipeline. On the Siberian platform, mineral deposits formed during the stages of formation of its basement (Aldan, Anabar, and Sharyzhalgai shields) and platform cover (Tunguska syncline, and Nepa-Botuoba anticline). Within the fold frame, ore formation was associated with subduction, spreading, collision, and plume tectonic intraplate settings. To start the development of small-size deposits and mining of technogenic raw materials, it is advisable to establish exploration and production enterprises that can operate and manage expeditions and use compact ore-dressing plants.

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.

<p>ROBOMINERS is developing an innovative approach for the exploitation of currently non-feasible mineral deposits. The approach entails the use of a robot-miner - a bio-inspired reconfigurable robot with a modular nature - in a new mining setting where the activities are nearly invisible and where mining presents less socio-environmental constraints, thus contributing to a more safe and sustainable supply of mineral raw materials.</p><p>The main aim is to design and develop a robotic prototype that is able to perform mining related tasks in settings including both abandoned, currently flooded mines not accessible anymore for conventional mining techniques; or places that have formerly been explored, but whose exploitation was considered as uneconomic due to the small-size of deposits, or their difficulty to access.</p><p>ROBOMINERS’ innovative approach combines the creation of a new mining ecosystem with novel ideas from other sectors, particularly robotics. At this point, work has been done to understand the best methods for the robotminer’s development in 1) biological inspiration, 2) perception and localisation tools, 3) behaviour, navigation and control, 4) actuation methods, 5) modularity, 6)autonomy and resilience, and 7) the selective mining ability. All these aspects combined aim to provide the robotminer XXI Century tools for mineral exploration and exploitation of (currently) unfeasible deposits.</p><p>At the same time, for the vision of a new vision of a mining ecosystem, work is involving studies on 1) developing computer models and simulations, 2) data management and visualisation, 3) rock-mechanical and geotechnical characterisation studies, 4) analysing ground/rock support methods, bulk transportation methods, backfilling types and methods, and 5) sketching relevant upstream and downstream mining industry analogues for the ROBOMINERS concept.  </p><p>After design and development, based on the previously mentioned studies, the robot-miner is set to be tested at targeted areas representatives which include abandoned and/or operating mines, small but high-grade mineral deposits, unexplored/explored non-economic occurrences and ultra depth, not  easily accessible environments. Possible candidates for testing purposes include mines in the regions of Cornwall (UK), mines in the Kupferschiefer Formation (e.g. Poland) or coal mines in Belgium.</p><p>When compared to usual mining methods the ROBOMINERS approach shows: 1) no presence of people in the mine, 2) less mining waste produced, 3) less mining infrastructure, 4) less investment, 5) possibility to explore currently uneconomic resources and 6) new underground small-sized mines, practically “invisible”. Altogether, ROBOMINERS can contribute to solve some of the main issues that make mining’s social license to operate so difficult to get in Europe: land-use, environmental limitations, and socio-economic aspects.</p>

The Russian Far East

The gold mining industry of the Russian Far East has a great development potential, whose economic growth largely depends on the efficiency of developing a unique mineral resource base. To do this, it is necessary to solve a number of tasks, including the management and organization of economic activities of enterprises engaged in the extraction of placer gold in medium and small volumes. Gold mining companies themselves positively assess the prospects for the development of the industry, despite the preservation of external restrictions imposed by Western countries. At the same time, the current position of the modern gold mining industry is determined not only by the state of the Russian economy, but also by a number of branch features related to the management of gold mining at the enterprise level. At the present time, there are increasing questions about the feasibility of consolidation of small and medium mining enterprises, which will allow them to overcome current trends in the economic development of the industry, by combining their own resources. At the same time, in practice, reverse phenomena are observed, indicating that the industry is segmented and the number of mining companies developing placer deposits is gradually increasing. However, consolidation processes, in the form of integration associations, represent one of the directions of development and effective functioning of Russian gold mining enterprises, therefore they require comprehensive research and remain relevant.

This article focuses on the problem how to classify regions according to their industry specialization using cluster analysis methods. There were selected 12 relative indicators as clustering parameters characterizing the importance of seven different sectors for the regional economies and the degree of state support of enterprises in these sectors. The classification procedure allowed to divide the studied regions into six clusters, each cluster received its working title. The first cluster is titled agro-industrial; it is characterized by the excessive national average indicators of the degree of state support in agriculture and power engineering in 2.4 and 1.6 times, respectively. The second cluster - industrial-presents regions with a high proportion of manufacturing activity using mainly imported raw materials. In the regions of the second cluster the federal government actively develops not only manufacturing and power engineering but power generation as well, 30.06% and 14.48% of total public investment, respectively. The third cluster - agricultural and construction - consists of traditionally agricultural regions and regions with rapidly developing construction sector. However, despite the fact that the value of agricultural industry in the third cluster regions is 2 times higher than the national average value, the degree of public support for the industry is still quite low. The fourth cluster - industrial and mining - brings together fifteen largest industrial regions, their activities are almost entirely provided by the domestic raw materials and energy stocks, which qualitatively distinguishes them from the second cluster regions. The fifth cluster - oil and gas production - is formed by seven richest regions in the federal districts of the Urals and the Far East, as well as the Nenets Autonomous District; these regions are characterized by the highest rates in mining industry. The sixth clusters - transport and power engineering - presents the group of regions with well-developed transport infrastructure and power engineering, many of them are major transport junctions in Russia. The results obtained are quite logical, appropriate and prove the effectiveness of the cluster analysis when processing large data sets. This fact confirms the validity and applicability of the cluster analysis in drafting regional strategic documents.

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 evolution of goals and objectives of the Energy Strategy of Russia for the period from 2003 to 2020 is considered. It is shown that the main priority of the foreign energy policy is to maintain and strengthen the country’s position in the world markets. It is determined that the country is actually consolidating the strategy of increasing production with the subsequent export of hydrocarbon raw materials. It is noted that the target indicators of the strategy, along with the share of Asia-Pacific countries in the geographical structure of Russian energy exports, is an increase in the share of primary energy production in Eastern Siberia and the Far East. The role of the Far East in Russia’s foreign energy policy agenda is analyzed. It is determined that the Far East acts as a transit territory and as a hydrocarbon and coal resource base. The development of the fuel and energy complex in the region is carried out within the framework of large energy projects in four categories: the Eastern Siberia - Pacific Ocean oil pipeline (ESPO) and the development of fields along the pipeline route; a set of interrelated projects within the Eastern Gas Program; development of the coal industry and related rail and port infrastructure; cross-border electricity exports to China

Тhe paper considers the main approaches to the valuation of mineral deposits. The valuation of mineral resources is widely used in countries with developed mining industry, such as the USA, Canada, Australia, etc. Monitoring the value of mineral assets allows you to track current changes in their structure and serves as a basis for the fair withdrawal of mining rent. The methods of financial and economic evaluation of mineral deposits are based on the standard methodology for investment projects assessment. The most widely used is the net present value method, which is used only for the estimation of commercial reserves. The resource assessment can be carried out using comparative methods and be used to improve the infor-mativeness of the assessment. The paper reviews the methods used to access the mineral resource potential of Russian regions, forms of statistical observation, and standards of the Russian Society of Appraisers. Contemporary Russian legislation in the field of mineral raw material valuation is based on international experience, where the main valuation method of mineral assets is the method of net present value. With the approval in 2017 of the statistical form "Information on the current market value of mineral reserves”, official annual data on the value of mineral raw materials in the subsurface appeared in Russia for the first time. The methodology for assessing the mineral resource potential of the region should include such stages as ranking mineral deposits according to their investment attractiveness, evaluating selected deposits with approved reserves using the net present value method with determining the budget efficiency of projects, and evaluating the gross potential value of resources of promising mineral resource objects.

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.
