he study of flooding of engineering structures as a dangerous engineering and geological process and the prevention of emergencies and environmentally adverse consequences is an important task of national economic importance. The purpose of this work was to study the natural conditions of the area of the Kadala airport in Chita to identify the main causes of flooding of the artificial runway (IVPP). The object of research was the near-surface part of the geological environment, the subject-the factors of formation of hydrogeological, engineering-geological and geocryological conditions. In the course of the research, the following tasks were solved: 1) identification of factors that affect flooding; 2) assessment and proposal of acceptable protective measures. The research methodology included: collection and analysis of materials from previous engineering and geological studies; interpretation of satellite images; field survey of the artificial runway and adjacent territory; analysis of hydrometeorological conditions. As a result of the research, the factors that lead to flooding of the south-eastern section of the airport, and in winter to the formation of ice and deformations on this section of the airport’s artificial surfaces are determined. The identified factors are divided into regional and local. The hydrogeological and engineering-geological conditions of the territory and their dynamics over time are considered. It is determined that the main factors of flooding are the creation of barrages in the path of the movement of underground water and the intensive freezing of the soil on the section of the artificial runway. Recommendations for the stabilization of the ground base on this site and measures for the engineering protection of the airport territory are given. The implementation of the recommendations will ensure the accident-free operation of the artificial runway and improve the environmental condition of the settlement adjacent to the airport from the south-east

The relevance is primarily due to the fact that the development of trans-border territories is becoming an important tool for successful regional cooperation between Mongolia and its neighbouring countries. In these circumstances, it is necessary to study and understand the functions and mechanisms of cross-border cooperation, which will reveal the difficulties that exist there today. Within the framework of trilateral cooperation, including in the field of economic relations, our states attention to the development of border areas naturally increases. The object of the study is the cross-border tourism cooperation between Mongolia, the Russian Federation, and the People’s Republic of China. The article is devoted to the analysis of mongolian-russian-chinese relations at the present time. The subject is about the ways, forms and mechanisms of regional tourism cooperation between the three countries, as well as the factors that hinder this process. The purpose and objectives of the article is to analyze the main directions of cross-border cooperation between Mongolia, Russia and China in the trade, economic and tourism sector on the example of the border areas of our countries; to show what opportunities we have that we are losing and the challenges that border regions to interact in a more effective and mutually beneficial. There have been used general scientific empirical and theoretical research methods. The usage of a comparative-functional, systematic approach, modeling and a logical method encourages to identify the essential and substantive elements of the regional cooperation of the Mongolia, Russian Federation and China. The Chinese side is more business like about this problem, the Mongolian side is only in the study stage, and the Russian side has not yet shown any initiative. Research shows that Chinese tourists are interested in visiting the Mongolian steppe and to Russia. This research shows that Chinese tourists are interested in exploring/seeing Russia and Mongolian steppe. Therefore, Khalkhgol somon is a region that can develop cross-border tourism within the framework of the “One Region-One Road” project of the People’s Republic of China. This study shows that there is an opportunity to turn this region into a cross-border tourism region involving certain entities from the three countries

The conclusions’ reliability of geologists who created the largest uranium ore base in the country on the territory of the Streltsovsky ore field (SOF) in the South-Eastern Transbaikalia, about the belonging of spatially isolated phosphate mineralization and powerful industrial mineralization to a final stage of Late Mesozoic tectonomagmatitic activation, is clarified. The relevance of the research lies in the need to study the geological materials at the SOF and the surrounding area to assess the prospects for involving in the exploitation of phosphate mineralization developed on the flanks of uranium deposits developed under the state program of the TOP. The object of study is the “blind” Argunskoye and Zherlovoye deposits and their western flanks on the surface, and the subject is the phosphate mineralization developed in the block of terrigenous-carbonate rocks. The purpose of the research is to clarify the time and features of the formation of phosphates, and the task is to assess the industrial significance of phosphate mineralization for decision-making. The methodology of scientific research is based on the interpretation of geological facts given in the literature and stock materials, use of concepts, terms, creation of hypotheses and their consequences, consistency of the comparison of which with the established facts determines the relatively high reliability of geological results. The author has used a descriptive method that takes into account a system of interrelated consistent positions, and a method of theoretical modeling, which raises the strategic goals of nature cognition to a higher scientific level. The results of the research are presented in three articles (parts). In the second part, phosphates of the region and SOF are characterized. It is established that the Talan manifestation of apatites belongs to the phosphate sorption-biogenic metalliferous formation of the Precambrian metamorphic rocks complex and combines the promising second and third most important industrial types of deposits. It is recommended to perform geological exploration at the evaluation stage and to test the electrothermal method for producing fused phosphate-magnesium fertilizers. In the third part, the known types of phosphogenesis and the genetic features of their manifestation in PSA are considered. Attention is drawn to the advantage of the recommended electrothermal method for processing apatite-carbonate and apatite-silicate rocks of the Talan manifestation

The article considers the aspects of changes in the economic and geographical position (EGP) of the Transbaikal Region at different territorial levels, and the factors that determine it. The aim of the study is to analyze the changes in the EGP of the region in historical retrospect, as well as to determine the possible influence of traditional factors and new factors of the institutional environment on these micro-level processes. It was revealed that there was a change in the emphasis on the importance of the Transbaikal Region at the macro and micro levels: the mineral and geological importance of the region in the country significantly decreased with the transition to market relations, while opportunities for cross-border cooperation with China and Mongolia opened up. Currently, special attention is drawn to factors of an institutional nature that can have a certain impact on the economic development of the territory. The focus of the study is on the micro-level of the region, where the Udokan field development project in the north of the Transbaikal Region is currently being implemented within the framework of the concept of the Territory of Advanced development (TOP) project «Northern Transbaikalia». The authors hypothesize that informal norms determining the economic behaviour of the population can resist state institutions that can influence the change in EGP. This confrontation has not been studied either in the Transbaikal Region or in other subjects of the Far East, where new mechanisms of state administration are being implemented. A fundamental factor in the development of the model territory of the north of the Transbaikal Region is its high resource availability. A significant role in the process of changing the EGP is played by the state Institute of the Territory of Advanced Development (TOP) «Northern Transbaikalia», which corrects the effect of traditional factors due to administrative and tax preferences. Informal institutional factors may be the environmental consequences of the development of the field and their possible impact on the traditional nature management of the indigenous small – numbered peoples of the north of the Transbaikal Region – the Evenks

The scientific and practical relevance, timeliness and practical and applied relevance of the selected research topics are empirically substantiated by the processes of sustainable development of world labour markets, improving the quality of human resources, increasing the importance of scientific and educational activities, acquiring unique competencies, knowledge and skills by workers of modern business entities, deepening specialization and differentiation of science-intensive enterprises, permanent scientific and technological progress and acceleration of the pace of formation of industrial-industrial clusters and venture business. The theoretical and practical goals of the publication are to study the socio-economic mechanisms for solving the theoretical and practical-applied problems of sustainable innovative development of the industrial economy and the implementation of science-intensive projects characterized by high production and economic uncertainty and significant socio-economic risk, which are not amenable to formalization. The theoretical and methodological basis of the publication was the scientific works of domestic and foreign scientists-researchers of socio-economic algorithms for the development of domestic and world economies of industry, as well as venture business. Scientific novelty lies in the critical rethinking of such a constructive and creative result of the venture business as the formation of public-private partnerships and the author’s interpretation of strategically significant science-intensive segments of the industrial economy (telecommunication technologies, medicine, microbiology, production of substitute products, innovative energy trends, the search for alternative sources of energy supply, etc. etc.). The practical significance of the results obtained lies in the comparative characteristics of the American and Eurasian strategies for the innovative development of industry, as well as the empirical argumentation of their socio-economic advantages and disadvantages. The article reveals a reduction in costs and a regression of transactions between production and economic services of American companies, savings due to the narrow focus of scientific and production processes with a simultaneous absence of material incentives for labour activity and the occurrence of costs due to the regulation of labour functions of workers. The use of a progressive system of remuneration of labour and bonuses to personnel of Eurasian companies has been established in the context of a simultaneous increase in resource and raw materials and monetary costs and the liberalization of in-house management, which are of priority importance for the formation of a strategy for the development of the Russian industrial economy

The problem of compositional analysis of extraterrestrial crystalline rocks in the study of celestial bodies is considered. Since most of the bodies, terrestrial planets and their surrounding objects may contain clinopyroxenes, it is possible to study the temperature and pressure of rock formation in certain areas according to the state of these minerals, and the studies can be carried out identically to the geothermobarometry of Earth rocks. The paper presents the results of experimental studies of clinopyroxene compositions of the basic model system CaO-MgO-Al2O3-SiO2 in the pressure range of 12...30 kbar and temperatures of 1325...1650 °C, which can be assumed as conditions for the formation of lunar rocks. The development of the necessary experimental data obtained in terrestrial conditions will help in the future to conduct remote studies of the Moon and other celestial bodies without the need to deliver soil to Earth. The revealed clinopyroxenes can be analyzed with existing geothermometers and geobarometers obtained for different ranges of P-T conditions. The possibility of creating a new geothermobarometer based on the distribution of minals or cations in clinopyroxene specifically for lunar rocks is not excluded. The main features and possible instrumentation of the apparatus intended for the study of the lunar surface are described. The study of different areas of the lunar surface will determine where the country rocks are located most closely to the surface. Analysis of silicate components of the lunar rocks will make it possible to get closer to the solution to the problem of initial composition of the lunar mantle

The article analyzes the possibility and efficiency of processing stale tailings of flotation plants of the copper pyrite complex. The resource potential, material composition and technological capabilities of processing a number of technogenic objects are considered. The interrelation and influence of mineralogical and technological factors on the choice of tailings processing technology are analyzed. The results of chemical, mineral and phase analysis of stale flotation tailings of the studied pyrite ores are presented. According to the complex studies’ results, it is established that the stale flotation tailings of copper pyrite ores belong to a refractory type of geo-resources due to the high content of pyrite and low, at the level of ppm, gold and silver content, which are present mainly in the “resistant” minerals - chalcogenides, sulphides, their intergrowths. The article presents a factor analysis and conditions for the elemental composition of tailings formation: mineralogical, technological and environmental. The territorial accessibility and technological capability of the investigated technogenic formations are analyzed. In the course of experimental studies, the elemental composition of stale tailings has been revealed - the main components of which are: iron, sulfur, silicon and aluminum. According to the results of X-ray phase analysis, it has been found that the main ore mineral of the tailings is pyrite. At the same time, it is noted that the main share of gold in the stale flotation tailings is presented in the form of sulphides in the form of finely dispersed and isomorphic inclusions. The heterogeneous morphometric and mineral composition of sulphide aggregates, their difficult opening and high dispersion characterize stale tailings as a raw material that is difficult to float. The revealed features of the material composition of stale tails indicate the impossibility of extracting valuable components (gold and silver) from this resource using existing traditional technologies. It has been proved that it is possible to effectively extract precious metals from this category of raw materials only after their deep opening by chemical processing. The relevance of the research lies in the need to process gold-containing man-made waste in order to significantly expand the raw material base of mining enterprises, as well as to improve the ecological situation of the city-forming mining enterprises of the South Urals. The aim of the research is to study the material composition of stale tailings and develop a technology for selective extraction of gold and silver. The object of research is the stale flotation tailings of copper-pyrite enterprises of the Southern Urals. The subject is the mineral composition, the content of useful components of lying tailings and the technology of gold and silver selective extraction from them. Material and research methods. During the experiments, a set of physicochemical and chemical methods of analysis has been used: thermodynamic analysis, synchronous thermal analysis using a combined thermal analyzer of the Netzsch STA 449 F3 Jupiter brand, UV spectroscopy with an automated data processing system), qualitative chemical and assay analyzes
