Harsh Conditions

Complex mechanical systems used in the mining industry for efficient raw materials extraction require proper maintenance. Especially in a deep underground mine, the regular inspection of machines operating in extremely harsh conditions is challenging, thus, monitoring systems and autonomous inspection robots are becoming more and more popular. In the paper, it is proposed to use a mobile unmanned ground vehicle (UGV) platform equipped with various data acquisition systems for supporting inspection procedures. Although maintenance staff with appropriate experience are able to identify problems almost immediately, due to mentioned harsh conditions such as temperature, humidity, poisonous gas risk, etc., their presence in dangerous areas is limited. Thus, it is recommended to use inspection robots collecting data and appropriate algorithms for their processing. In this paper, the authors propose red-green-blue (RGB) and infrared (IR) image fusion to detect overheated idlers. An original procedure for image processing is proposed, that exploits some characteristic features of conveyors to pre-process the RGB image to minimize non-informative components in the pictures collected by the robot. Then, the authors use this result for IR image processing to improve SNR and finally detect hot spots in IR image. The experiments have been performed on real conveyors operating in industrial conditions.

The mining industry in the world has undergone a major metamorphosis in recent years. These changes have forced higher education to modify the curricula in a thorough way to meet the mining entrepreneurs’ needs. The paper’s scope is to answer the research question—how to attract students and implement Sustainable Development Goals (SDGs) in higher education in mining engineering? Based on the case of international cooperation carried out at the Faculty of Geoengineering, Mining and Geology of the Wrocław University of Science and Technology (WUST) within the framework of educational projects co-financed by European Institute of Innovation and Technology (EIT) and EIT Knowledge and Innovation Communities Raw Materials (EIT RM), the authors prove that the idea of sustainable development can be introduced into the system of teaching mining specialists at every level of their higher education (engineering and master’s studies), through developing their new competencies, introducing new subjects taking into account innovative solutions and technologies, or placing great emphasis on environmental and social aspects. Examples of new curricula show a good way to change into the new face of a mining engineer.

This article deals with the problem of preserving the properties of a semi-finished fur product under the influence of a biological factor during the storage of raw materials. The characteristic features of the biodegradation of untreated rabbit skins during storage at elevated temperature and relative humidity are identified and described. A complex characteristic of a semi-finished fur product developed from raw materials of various degrees of microbiological spoilage is given. The author offers a point scale of assessment dynamics of the processes of destruction of fur raw materials and a point assessment of the organoleptic indicators of the semi-finished product was developed. As a result of comprehensive studies, it was found that the degree of damage to the fur raw materials being processed affects the decrease in the stability of the structure and strength properties of the finished semi-finished product.

The Murmansk region is a region with the largest enterprises of the mining complex of the Russian Federation: KF JSC “Apatit”, JSC “Kola MMC”, JSC “Olkon”, JSC” Kovdorsky GOK”, JSC” North-West Phosphorus Company”, LLC”Lovozersky GOK”. They provide the majority of the country’s demand for phosphate ores, zirconium raw materials (baddeleyite), niobium, tantalum, and rare earth metals. In addition, the mining and processing of copper-nickel, iron and chrome ores, nepheline and ceramic raw materials, facing stone and building materials is carried out. At the same time, the activities of enterprises have a very negative impact on the environment. The issues of environmental safety in the extraction and processing of minerals, storage of mining waste in the Arctic zone of the Russian Federation are of particular relevance. The definition of sustainable development in relation to the mining industry is given. The concepts of available best technologies, circular economy, and “green growth” are considered from the point of view of their contribution to sustainable development. It is shown that the sustainable development of enterprises at the present stage is impossible without improving the environmental friendliness of production. The article analyzes the legislation of the Russian Federation and the practice of its application to identify mechanisms that promote sustainable development and eliminate barriers to the implementation of this concept in the mining industry. New technological solutions have been developed for mining enterprises of the Murmansk region, aimed at reducing aero-technogenic emissions, cleaning waste (mine) water, processing tailings of enrichment as man-made deposits, which allows both to minimize man-made environmental impacts and to increase the full use of mineral raw materials. Thus, the expediency of using the principles of “green growth” for the development of economic development policies in the Arctic is justified.

There is a worldwide trend of increasing the share of extraction and processing of low-grade minerals, but their extraction and processing volumes are still low. There are several reasons for this: high mining and transportation costs, imperfect techniques and technological difficulties in enrichment and processing of refractory and low-quality minerals. Due to the depletion of reserves of easily beneficiated raw materials and to compensate for the growing shortage of high-quality minerals, the Russian mining industry development strategy provides for the involvement of new and unconventional types of deposits into production. Examples of such deposits are deposits of carbonaceous raw materials (black shale, refractory sulphide carbon-bearing ores, impactites, etc.) containing carbon of varying degrees of metamorphism. On the basis of the most modern mineralogical, physical, nuclear and chemical methods of research of composition, structure and properties of the carbonaceous raw materials at the micro- and nanolevel, the composition of the productive mineral matter, physical, chemical and thermodynamic laws of separation of valuable mineral components and the basic technological processes to obtain the finished product for valorization of the unconventional carbonaceous mineral raw materials were determined with maximum reliability. One of the possible reasons of difficulty of beneficiation of carbonaceous raw materials is the fine phenocrysts in graphite which can be solved by using the flotation process. Contrast of surface properties of minerals with similar technological properties can be increased by application of different energy effects (MEMI, MIO, microwave, electrochemical treatment etc.) at successive stages of raw material transformation, regulation of pulp conditioning conditions (duration and intensity of agitation, heat treatment of pulp) as well as by development and application of selective reagent regimes. The special feature of flotation as a method of extraction of noble and rare metals is the ability to extract valuable metals not only in their native free form, but also in close association with sulphides and carbon. Flotation with the use of intensifying influences made it possible to transfereven low-sized structures of noble and rare metals, which are not extracted by conventional methods of cyanidation, gravitation enrichment and amalgamation, into the concentrate. One of the ways to increase the efficiency of the flotation process is preliminary modification of the additive which is introduced in addition to the main reagents of the sinter - “carrier material”.

<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>

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.

Further development of the open mining works on the domestic enterprises will be accompanied by the worsening of mining-geological conditions and declining of the quality of iron ore raw materials. In the same time, the accumulated mining wastes, that can make the technogenic deposits, pass into one of the important sources of the mineral raw materials. Taking into account this thing, the development and implementation of the modern technological circuits of the technogenic deposit development is an actual calling for mining industry, and determination and optimization of process conditions of the technogenic deposit development – is the scientific task of this publication. The obtained results of studies of the optimum step value of the ore chute transfer during the technogenic deposit development can be used by design organizations and mining enterprises for designing works. The obtained methodology and the proposed mathematical dependencies will reduce the cost of mining of the technogenic deposit due to the reasonable timely transfer of the open ore chute.
