Introduction. The works devoted to the theme of the sustainable development of the Ural settlements show that the primary source of the culture-centrism of rural everyday practices is the forms of people's cultural activities that have historically developed in the Russian countryside. The cultural resources of the territory and the cultural activity of the population are recognized as important components of settlement systems. But they do not create a quick economic effect, so they play a secondary role. However, the development of territorial branding is an important factor in the sustainable development of rural areas. Materials and мethods. The method of content analysis was used in the work. The geography of the study was limited to the rural settlements of the Urals. Results. The applied use of original works of arts and crafts in territory branding is relevant for settlements where the results of people's cultural activities are in demand by actors in the hospitality industry. As an example, the paper cites the experience of the activities of creative groups of large villages in the Urals. An important role in the territorial branding of urban and rural settlements is played by cultural events (festivals, fairs, etc.). Vibrant cultural events are a necessary component of branding. Using ancient art is a possible way of branding. For the Ural-Siberian macro-region, these are the "Scythian-Siberian animal style" and "Permian animal style". Natural and cultural attractions are equally important means for implementing branding strategies. Discussion. When using the tools of the geocultural approach in the discussion of pilot scenarios for the development of the experience economy in rural settlements, it is necessary to be based on the semantic constructs of the concepts of "rural geoculture", "geocultural space of the village", "image of rural geoculture", "geocultural branding of the village". It seems logical to consider the geocultural branding of a rural settlement as a practice-oriented part of the geocultural strategy for the development of a rural district. Conclusion. The methodological "turn" of a number of researchers to the study of branding of cities and rural settlements through culture is due to their recognition of the culture-centricity of local communities. Currently, the cultural resources of urban and rural areas are used by stakeholders to develop the hospitality industry. Territory branding is in demand today, focusing on the promotion of urban and rural brands. Resume. It is shown that territory branding is the most important factor in the sustainable development of the Ural settlements. It has been established that it is possible to ensure the sustainable development of the potential of a rural area through the implementation of a geocultural branding strategy. The results of the research can be useful in the development of programs for the development of territories.

The most important link in the process chain for creating waste-free technology at concentrating plants is to ensure the possibility of using tailings, where the bulk of non-metallic minerals, rare earth minerals or overburden is concentrated. Increasingly, mining enterprises store their waste, forming man-made deposits. Thus at present time, the development of section technogenic deposits containing tailings is becoming a pressing challenge. The characteristic feature of such deposits is the polydispersity of the developed material, which makes it difficult to determine the fragmentation index. Therefore, the objective of this paper is to study the influence of the grain size distribution of tailings on the fragmentation index during the formation of an technogenic deposit, wherein said index affects the performance of mining and transport equipment, as well as the safety of mining operations. This paper is prepared with the application of the method of mathematical analysis, as well as a laboratory method, including determination of the volume of the pore space by displacement of the liquid phase from a container with a polydisperse mixture and measuring of weight indicators. The polydisperse mixture is represented by a fraction of 0–0,2 mm, 0,2–0,8 mm, 0,8–2,0 mm, 2,0–4,0 mm. 4,0–8,0mm, 3,0–12,0mm. An analysis was made of the influence of 5 indicators on the loosening coefficient. As a result of the study, it was found that the main criterion affecting the loosening coefficient is the ratio of coarse to fine class in the mixture, and not the size of the weighted average particle in it, and the smaller this ratio, the lower the loosening coefficient approaches 1. Class 1 reception in subsequent calculations. The results obtained will become the basis for studying the loosening factor in the development of man-made deposits, represented by tailings, and require further improvement of the theoretical foundations and industrial use.

Introduction. The paper considers a method for calculating the parameters of a roller crusher developed on the basis of established analytical dependencies: the theoretical and technical productivity of spalt sieves from the share of the total volume of rock mass, as well as the productivity of a roller crusher when overlapping spalt sieves with metal sheets. Purpose of the work: development of a methodology for calculating the parameters of a roller crusher. Methods and Materials. To achieve the goal of developing a methodology for calculating the parameters of a roller crusher, a search and analysis of materials on this topic was carried out. Research. The resulting method of calculating roller crushers allows you to evaluate the proposed equipment and, if necessary, select a control scheme for its main technical characteristics. Discussion. In the calculation method of a roller crusher, first of all, it is necessary to determine its main parameters, namely its technical performance, to identify the compliance of the obtained parameters with the requirements of further technological links. After determining the main parameters of the crusher, the design is adjusted and its parameters are adjusted, the technical characteristics of roller crushers have high values and various variants of the overlap schemes of the trellis sieves and the roll of the crusher are recommended to reduce the productivity of roller crushers. Conclusion. Studies have shown that the proposed method is suitable for calculating the technical characteristics of roller crushers. Summary. With successful testing and obtaining positive results of the method of calculating the parameters of the roller crusher, it can be successfully applied to the selection of equipment for the development of new enrichment systems. Also, studies have shown that roller crushers require the use of overlapping schemes of trellis sieves and roll.

Introduction. The North is traditionally perceived as the endless plains used by reindeer herders for long-distance migrations. However, polar regions are also represented by the mountains with specific nature management. Sustainability is characteristic of historically established ways of management in the mountains based on spatial and temporal organization of landscapes adapted to local conditions at the most. The Polar Urals is the historically existing areal- the joint habitat of different peoples: the Nenets people (prevailing among indigenous peoples of the Russian North), the Khanty, and the Komi-Zyryans. At present, the Polar Urals is one of the stable centers of traditional reindeer husbandry. Climate change and “civilization” influence are challenges to traditional mountain nature management as they introduce a number of uncertainties into the existing system of interaction between the population and nature calling for local communities adaptation. Materials and methods. In this study, the method of interviewing based on the authors’ questionnaire was used. Results. The regional specifics of the mountain nature management and self-identification of reindeer herders of the Polar Urals as compared to other clans of their ethnic groups are shown. Besides pastures, water and wood (being decisive in the well-being of local communities) are among most important natural benefits provided by the Polar Urals landscapes. Conclusion. The reindeer herders of the Polar Urals try to preserve the traditional nature management through successful adaptation to modern challenges (e.g. climate change). To a large extent, they consider the introduction of novel technical achievements positively. Suggestions for practical application and direction for future research. The results of the study can be used in the preparation of regional and municipal programs to support traditional nature management in the Polar Urals, and the development of measures to adapt it to modern challenges.

The purpose of the study: analysis of geoecological factors and conditions affecting the sustainability of agricultural land use in the forest-steppe zone of the Altai Krai and its assessment. Research methods: System analysis (landscape analysis) was used in the study of geoecological factors and conditions affecting the landscapes of the study area. The methodological basis of the study was the work of Russian and foreign scientists who at different times studied the problems of climate, soil formation, sustainable development and food security. Monographic, statistical, cartographic methods, methods of GIS technologies and modeling were used in the analysis of areas and land types of the object under study. Research results. The author's approach presented in the paper allows at the local level (land use of an agricultural organization or municipal district) to assess the impact of geoecological factors and conditions on the sustainability of an agricultural territory. On the example of a typical territory for the agrarian regions of the south of Western Siberia and Northern Kazakhstan with an area of about 3000 km2, located in the forest-steppe zone of the Altai Krai, an assessment was made of physiographic, climatic, geomorphological, soil conditions, natural and anthropogenic factors. 11 assessment indicators were identified, which clearly showed the limiting impacts on agricultural landscapes, manifested in the territory in the form of erosion processes that reduce the efficiency of agricultural production. The established regularities of the influence of geoecological conditions and factors make it possible to differentiate the development of a complex of agro-, phytoforestry and reclamation measures aimed at achieving the ecological and economic balance of the territory and, as a result, increase the stability of agrolandscapes at the local level. Conclusions. 1. An algorithm for assessing geoecological conditions and factors at the local level of organization of agricultural land use has been determined to analyze its sustainability. 2. The assessment of the agrarian territory revealed the limiting impacts on the relief, geological structure of the area, soil condition, microclimate of the natural environment, structure, quality of land and other conditions and factors. Limiting impacts on agricultural land use are expressed in the manifestation of erosion processes, high land intensity and low environmental sustainability of the territory, which affects the efficiency of land use. 3. The results of scientific research can be used in the management of land resources at the level of a municipal district and an agricultural organization.

Introduction. The article presents the results of research on the problem of waste disposal of ore processing by changing the properties of metal-containing raw materials. The research methods are based on experiments using the method of electrochemical activation of metal extraction processes. Results. The purpose of the study is formulated as modernization of the technology of extraction of metals from ores by leaching in relation to non-ferrous metals. It has been determined that the tailings of the enrichment of metal ores contain valuable metals that are not fully extracted by traditional methods of enrichment, which form compounds dangerous to the environment. It is determined that the leaching efficiency increases due to a decrease in the activated reaction area of the working solution with minerals containing the extracted metal. A mathematical description of the leaching kinetics is given depending on the surface area of the particles and the applied energy. Models for evaluating technology options and determining savings from the use of the phenomenon of mechanical activation are proposed. Discussion of the results. It is shown that a promising direction of metal extraction is combined chemical enrichment and mechanical activation with high energy in a disintegrator. It is determined that the activation of minerals in the disintegrator increases the recovery of metals by more than one and a half times, and the combination of grinding and leaching processes increases it even more. Conclusion: during the disposal of ore dressing waste, the mechanochemical activation of binders increases the extraction of metals, reducing risks to the environment.

Introduction. In an era of economic transnationalisation, global shocks have a significant impact on economic subjects. Resource-dependent countries and economies are particularly sensitive to global shocks. There are common parallel between countries dependent on imported resources and regions with mineral resources on the verge of depletion. Recycling of industrial waste is a vector of mining development that reduces the dependence of economies on sharp fluctuations in commodity markets in times of global shocks. The proposed vector allows solving replenishment of the mineral resource base of the enterprise or countries dependent on the import of resources. The development of innovative technologies from simple minerals extraction from the subsoil to a full-cycle process of georesources exploitation, including full processing of industrial waste, will contribute to resource provision for sustainable development. Purpose of work. To identify industrial deposits, study and systematise their chemical and mineralogical composition and determine their recycling potential for the further recycling of industrial waste from mining and processing sectors. Methods and materials. The object of the study is industrial formations (tailing dump) which are part of a single mining holding Ural Mining and Metallurgical Company of Gayskaya, Sibayskaya, Uchalinskaya and Buribayevskaya plants. The laboratory and experimental part of the study was facilitated by various methods: theoretical (analysis, generalisation; classification, etc.); practical (observation; comparison; measurement; experiment, etc.). The study of tailings was carried out by simple sampling according to a preformed grid of pits. The pits were made on the tailing beaches (drained areas) on a 60x60 meter grid to a depth of 6 meters. The study comprised an assessment and visual approbation which consisted of interval-by-interval sampling of flotation tailings (test material) from the pits at each half-metre interval. To reduce the volume of test material, samples were averaged by simple quartering. Selected samples were sent to the laboratory for physical examination. The samples were examined by X-ray analysis. A DRON-3M instrument was used to analyze the samples. The study was conducted by Co-radiation with the use of Fe-filter. X-ray phase analysis was used to process the obtained spectral data where the Joint Committee on Powder Diffraction Standards (JCPDS) was applied. Microstructural research of the averaged sample mineralogy was conducted on material with a particle size of -1+0.25 mm using a Philips SEM 515 scanning electron microscope. The possibility of extracting a valuable component from tailings was assessed on the example of gold using double agitation cyanidation. Results of research. The results of the visual study show that horizontally layered structure is traced in all tailing dumps of all pits. This is due to the successive reclamation of the layers. At all the tailing dumps
介绍在经济跨国化的时代，全球冲击对经济主体产生了重大影响。依赖资源的国家和经济体对全球冲击特别敏感。依赖进口资源的国家和矿产资源濒临枯竭的地区之间有着共同的相似之处。工业废物的回收利用是矿业发展的一个载体，可以减少经济体在全球冲击时期对大宗商品市场剧烈波动的依赖。所提出的矢量可以解决依赖进口资源的企业或国家的矿产资源基础补充问题。开发创新技术，从从底土的简单矿物提取到地理资源开发的全周期过程，包括工业废物的全面处理，将有助于为可持续发展提供资源。工作目的。识别工业矿床，研究并系统化其化学和矿物学组成，并确定其回收潜力，以进一步回收采矿和加工部门的工业废物。方法和材料。本研究的对象是工业地层（尾矿堆），该工业地层是Gayskaya、Sibaystkaya、Uchalinskaya和Buribayevskaya工厂的乌拉尔矿业冶金公司的一部分。研究的实验室和实验部分通过各种方法进行：理论（分析、概括、分类等）；实际（观察、比较、测量、实验等）。尾矿的研究是根据预先形成的坑格通过简单采样进行的。这些坑是在尾矿海滩（排水区）上形成的，网格为60x60米，深度为6米。该研究包括评估和视觉认可，包括以每半米的间隔对矿坑中的浮选尾矿（试验材料）进行逐间隔采样。为了减少试验材料的体积，通过简单的四分之一法对样品进行平均。选定的样本被送往实验室进行体检。通过X射线分析对样品进行了检查。使用DRON-3M仪器对样品进行分析。本研究是用钴辐射和铁过滤器进行的。X射线相位分析用于处理所获得的光谱数据，其中应用了粉末衍射标准联合委员会（JCPDS）。使用Philips SEM 515扫描电子显微镜对粒径为-1+0.25mm的材料进行平均样品矿物学的微观结构研究。以金为例，采用双搅拌氰化法对从尾矿中提取有价值成分的可能性进行了评估。研究结果。可视化研究结果表明，所有矿坑的所有尾矿堆都有水平分层结构。这是由于层的连续回收。在该矿的所有尾矿堆中，无一例外地在所有矿坑中都发现了工业硫酸盐。在1-2m的深度下观察到硫酸盐形成的活性过程。实验室测试显示有价值成分含量的百分比：铜；锌铁硫磺金和银，这使得能够确定工业形成物中适合提取的有用组分的大致量。为了充分表征工业原料，建立了有价值成分的定性指标，即研究了提取它们的可能性（以黄金为例）。实验室方法确定，从尾矿中提取金的比例在75,9到82,14%之间，这取决于所研究的工业原料。讨论对所得数据的分析表明，Gaisky选矿厂浮选尾矿中50.88%的黄金为耐火材料。未发现可供提取的游离黄金。相分析结果证实了矿物组合中存在易于氰化的金。易氰化金占所检加工废料中金总体积的49.12%。从Buribayevsky加工厂提取的实验室分析样本显示，工业储存中不到一半的黄金是耐火材料（40.31%）。此外，还没有发现可供提取的游离黄金。在Buribayevsk选矿厂的调查废物中，易氰化金占金总体积的59.7%。结论1.本文考察了乌拉尔矿冶公司的尾矿库，确定了尾矿库的材料和矿物学组成。尾矿堆由相同类型的加工材料组成，因此采用了类似的加工技术。2.已对工业废物中残留的有价值成分作了大致估计。3.

The quality of powder materials made of rare metals is ensured by chemical-thermal treatment, including diffusion chromosilidation. Chemical and thermal treatment of products intensifies the process of diffusion saturation, reduces the processing time and allows the use of products in aggressive and abrasive environments.

Introduction. The use of geohods for the development of underground space is an innovative approach, the essence of which is the use of geo-media in the rock mass to create traction forces. The constructive and functional requirements for the working bodies are being developed, which take into account the nature of the movement and functionally constructive differences, the formation of a specific form of slaughter obtained during the operation of the working body, in which the working body is made in the form of helicoids shape. To implement technological solutions, it is necessary to select and justify the materials of the working body of the geohod. Materials and methods. The paper considers the basic requirements for the materials of the working body of the geohod, based on the structural, functional and technological features of the design of the geohod. The paper notes that the cutting edge of the working works in particularly harsh conditions, therefore, materials such as alloy steels with high wear resistance are recommended for this type of construction. Foundry alloy steels and high-strength alloy alloys are considered as rational options. Research results and their discussions. Taking into account the features of the equipment, the physical and mechanical properties of the rock being destroyed, the strength characteristics of the recommended materials and their technological properties, when choosing materials, emphasis is placed on the mechanical properties of materials and wear-resistant properties, which are important parameters, since abrasive wear of the working surfaces occurs when the working body of the geohod. Conclusion. The recommended alloyed alloys with high strength meet all the requirements that are imposed on the design of the knife of the executive body, but do not meet the technological requirements, namely, they are quite difficult to deform, difficult to process by cutting and welded. Considering all the technological properties that are significant in the implementation of the manufacturing technology of the working body of the geohod, it is recommended to choose more durable materials that withstand large continuous loads. Resume. The article presents the results of research to determine the choice of material for the manufacture of the working body of the geohod. It is established that for the manufacture of the working body, when using the casting technology of production, steel 30ХГСА can be used, when processing pressures – steel 18Х2Н4МА. Suggestions for practical application and direction of future research may be useful for the development of manufacturing technology of the main elements of the working body of the geohod.
