Актуальность проблемы комплексного освоения и сохранения недр в настоящее время повышается необходимостью совершенствования основанных на новых принципах технологических процессов, что объясняет необходимость разработки новых и модернизации известных методов управления геодинамическими явлениями в массиве. Объектом исследования являются скальные сложно-структурные месторождения Садонской группы Центрального Кавказа, разработка которых увеличивает напряжения в рудовмещающих массивах с ухудшением качественных показателей использования недр и делает необходимым учет технологических воздействий на массив и меры геомеханического мониторинга его состояния. Целью исследования является обоснование возможности и целесообразности использования продуктов горного и обогатительного передела руд и изготовленных на их основе после извлечения из них полезных компонентов закладочных смесей. Методы достижения поставленной цели исследования включают в себя систематизацию и ранжирование связанных с управлением массивом геологических, технологических и экономических данных, разработку критериев оптимальности и формирование концепции ресурсосберегающей технологии разработки месторождений. Результаты. Детализирована концепция управления геомеханикой рудовмещающих массивов. Дано условие прочности массива на различных стадиях разработки месторождения. Предложена математическая модель взаимодействия переменных факторов. Сформулирован механизм сочетания традиционной технологии с открытым выработанным пространством и новой технологии с выщелачиванием металлов, как в блоках, так и в дезинтеграторах. Даны результаты оценки возможности использования хвостов обогащения в качестве сырья для изготовления твердеющих смесей, полученные в ходе полнофакторных исследований по программам государственных грантов. Даны сведения о гидрохимических способах получения металлов на рудниках. Вмещающим породам Садонских месторождений характерно перераспределение напряжений, в том числе, в геодинамическом режиме. Управление геодинамикой рудовмещающих пород путем регулирования величины напряжений в рудовмещающих массивах требует использования искусственных массивов из хвостов технологических процессов. Показано, что отработка вовлекаемых в производство некондиционных руд и хвостов обогащения запасов и доработка имеющихся запасов по комбинированной схеме может быть рентабельной Relevance of the problem of integrated development and conservation of mineral resources is currently increasing by the need to improve technological processes based on new principles, which explains the need to develop new and modernize well-known methods for managing geodynamic phenomena in the massif. Aim.The object of the study is the rock complex structural deposits of the Sadon group of the Central Caucasus, the development of which increases stresses in ore-bearing massifs with a deterioration in the quality of subsoil use and makes it necessary to take into account technological impacts on the massif and measures of geomechanical monitoring of its condition. The aim of the study is to substantiate the feasibility and advisability of using the products of mining and concentration processing of ores and made on their basis after extracting from them the useful components of filling mixtures. Methods to achieve the research goal include systematization and ranking of geological, technological and economic data related to managing an array of data, development of optimality criteria and the formation of a concept for resource-saving technology for field development. Results. The concept of managing the geomechanics of ore-bearing arrays is detailed. The condition of the array strength at various stages of field development is given. A mathematical model of the interaction of variable factors is proposed. The mechanism of combining traditional technology with open mined space and a new technology with leaching of metals, both in blocks and in disintegrators, is formulated. The results of evaluating the possibility of using enrichment tailings as raw materials for the manufacture of hardening mixtures, obtained in the course of full-factor studies on state grant programs. Information is given on hydrochemical methods for producing metals in mines. The host rocks of the Sadon deposits are characterized by a redistribution of stresses, including in the geodynamic regime. Management of the geodynamics of ore-bearing rocks by regulating the magnitude of stresses in ore-bearing massifs requires the use of artificial arrays from the tailings of technological processes. It is shown that the mining of substandard ores and tailings from the enrichment of reserves involved in the production and the refinement of existing reserves using a combined scheme can be cost-effective

The article presents the overview of the main technological processes in fish structured products dehydration. The rational modes of the technological process of minced fish raw materials with various initial moisture and fat content heat treatment are determined. One of the main tasks of the fish processing industry development which allows increasing the profitability of products and their quality is improving technological processes. The scientifically substantiated choice of resource and energy-saving modes of processing food materials is highly important in this case. It will reduce not only production costs but also emissions of harmful substances into the environment and increase the efficiency of using equipment. It must be taken into consideration that the optimization of dehydration technological processes without identifying their patterns is extremely difficult. Increasing efficiency and controlling technological processes makes sense only on the basis of patterns. The effectiveness of the hydrobionts processing determines the quality and cost of finished products manufacturing while fish processing enterprises working. The development and implementation of highly efficient technologies with the use of resource-saving technical systems, for example, using heat pumps, makes it possible to produce cost-effective high-quality products.

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.

This paper summarizes the findings of the research aimed at the development of a new method for the integrated processing of naturally occurring and anthropogenic rare-earth raw materials based on the decomposition of rare-earth element (REE) concentrates in the presence of sulfocationite. Sorption and desorption of REE cations on a strongly acidic ion exchanger, sorbent regeneration, and REE recovery from eluates are discussed. A virtually zero-waste integrated process for apatite concentrate is proposed. The generalization of the research findings is aimed at demonstrating the prospects and universality of the proposed resource-saving and environmentally safe approach to the processing of various types of naturally occurring and anthropogenic rare-earth mineral feeds. The new methodology made it possible to develop a number of new hydrochemical processes united by a single approach, providing a qualitative increase in the processing performance of various types of rare-earth mineral feeds. The theoretical foundations of a unified approach to the processing of a wide range of minerals can significantly accelerate and cheapen the implementation of specific process circuits, significantly reduce reagent consumption and waste generation, simplify the separation of rare earth elements and impurities, and the separation of rare earth elements from naturally occurring radionuclides, fluorine, and phosphorus. The study was funded by the Kolarctic CBC 2014-2020 program, Project KO1030 SEESIMA — Supporting Environmental Economic and Social Impacts of Mining Activity.

Abstract Multistage fracturing (MSF) ball drop completion systems have been utilized around the globe for effectively treating formations completed as open hole and cemented. Multiple, high-rate hydraulic fracturing stages are pumped through these completions while gaining efficiency during pumping operations. A challenge within the industry was developing systems that are capable of higher pressures (greater than 10k psi) while still being able to be deployed in challenging openhole environments with minimum equipment and intervention requirements. This paper will discuss the planning, deployment and fracturing execution operations of an improved version of one of these systems. To be able to effectively utilize any MSF completion system; formation properties, deployment environment, lateral length, openhole size, liner size, and tubing movements during fracturing should be thoroughly analyzed and equally considered. To create a reliable system, another important consideration is how the system will be deployed; a long string to surface, or will it be deployed as part of a liner hanger system? In the case of the latter, it should be compatible with the liner hanger system by accommodating multiple balls to set and release the hanger system and actuate the openhole packers. In tight formation environments, where treating pressure differentials reaches as high as 15,000 psi during fracturing operations, openhole packers that are capable of holding these pressures in challenging openhole conditions are needed. Not only the packers but also the remaining completion system components need to be capable of withstanding, including burst, collapse, and ball-to-ball seat differential while simultaneously accommodating the pressure with cooling and ballooning induced tubing movement caused by these high pressure treatments. Improving such a robust design with innovative solutions, such as dissolvable frac balls that can handle 15,000 psi differential, optimizes the overall process. The completion design, deployment, and subsequent fracturing operations on a well showcases how effective consideration of components operates as a system can create a reliable MSF system. It also demonstrates how close collaboration between reservoir management, production engineering, completion experts, and vendor results in a coordination of efforts that eliminates operational hazards, thus ensuring smooth operations. The successful deployment of an openhole MSF completion system that can handle 15,000 psi with dissolving frac balls and eliminating openhole anchors helped pave the way to deal with tighter formations in an efficient and cost-effective manner. With the help of this new technology, the well planners were able to address operational challenges that would have otherwise required additional equipment or would have limited deployment capabilities. The engineering approach and design to develop this completion system and utilization in the right candidate confirmed the benefit of the novel completion for field development options.

It is proposed to conduct selective extraction of conditioned and substandard ore of an exploded complex structural unit using an improved mining aggregate equipped with a classification grid with rotary grates and a crusher with an adjustable size of the discharge gap, which will allow one of the basic principles of resource saving - not to crush anything superfluous. The proposed technical and technological solution will significantly increase the productivity of mining operations, increase the extraction of mineral raw materials from the developed complex structural unit due to separation from substandard ore enriched with a useful component of ore fines, as well as reduce dusting and reduce the loss of mineral raw materials from blowing and spilling during loading and transportation.

During underground mining of deposits of valuable non-metallic raw materials, nonferrous and precious metal ores, the problem of their overgrinding as a result of blasting is quite acute. Overgrinding of valuable non-metallic raw materials leads to an actual decrease in the yield of concentrates or final products, due to the rather stringent requirements of the enrichment technology for the conditional size of the piece and the structural safety of the useful component. Non-ferrous and precious metal ores represented by strong rocks are characterized by the effect of increased concentration of ore minerals in small classes of ore. Due to the process of segregation on ore drawing, small fractions in significant quantities accumulate on the lying side of the goaf and its unevenness. Such ore with a high content of useful component requires additional technological measures for its extraction or is simply lost. Consequently, the development of technological methods for managing the quality of products of a mining enterprise and methods for increasing the completeness of extracting mineral resources are an urgent scientific and technical task. To solve it, an analysis of theory and practice in the study area was carried out, which showed that the existing methods for additional extraction of fine ore fractions in mining systems with an open goaf are laborintensive and resource-intensive, not universal, ineffective and often not safe. It is rational to create conditions for reducing the yield of fine fractions already at the stage of ore blasting As a result, determining parameters principles for breaking technology of strong fractured ores are proposed. Developed guidelines and recommendations for blasthole ring charges. Dependences the technical and economic indicators of ore explosive blasting from its structural and technological parameters are obtained.

Based on complex structural, geological, and mineragenetic metallogenic studies, taking into account the results of earlier subject-specific, prospecting, mapping, and exploration works, it has been established that Upper Paleozoic and Early Mesozoic tectono-magmatic structures are widely developed within the ore district. They are associated with the development of the transregional Upper Paleozoic Selenga-Vitim volcano-plutonic belt of riftogenic type as well as with the formation of the Early Mesozoic Western Transbaikalian zone of intraplate magmatism. The main commercially important mineral raw material resources of the Selenga ore district which are located in the ore clusters (the Kunaley, Kizhinga, Cheremshanka-Oshurkovo, Tashir etal.) and beyond their bounds are associated with the Late Paleozoic-Mesozoic magmatic activity. It is shown that molybdenum and beryllium are the main ore mineral resources within the investigated ore district which establish its mineragenetic features. The new material characteristics of the Upper Paleozoic and Early Mesozoic intraplate magmatic complexes and the associated deposits of mineral raw materials (Mo, Be, Ti, quartz, fluorite and apatite raw materials) and other promising ore objects of gold, uranium and rare-earth-barium-strontium mineralization are obtained. The geodynamic conditions of their formation and the main age boundaries of the ore-forming processes are revealed, the prospects of mining in the Selenga ore district and the involvement of this ore potential in the program of the regions economic modernization are estimated.

The exploration industry of Ukraine is experiencing a protracted crisis. It is confirmed by the curtailment of funding for the development of country mineral resources by 60% last year which causes the closure of exploration companies. The range of problems traditionally solved by the geography of mineral resources is significantly reduced. These reasons encouraged us to consider the main methodological approaches to the study of mineral potential of specific regions. The studied approaches such as natural-geographical, economic-geographical, ecological-geographical, and complex structural-geographical lie in the domain of geographical science. The article emphasizes the urgency to develop structural and geographical course of research, which is based on the studies of mineral resources and the approaches mentioned above including geological one. The structural and geographical course of research is supposed to create real models of mineral resources of the country regions and to suggest specific measures of their structure optimization alongside prospects of their development following modern world tendencies. The research may result in the creation of a long-term concept of balanced development of the mineral complex of the region, the prevision of the use of mineral resources, the justification of resource-saving technologies. A systematic approach to such a concept will ensure the rational use of resources, the formation of new infrastructure, conditions for environmentally safe function of the economy, sustainable and balanced development of the economic complex of the region.
