- Abstract:
- The article presents the results of studies of the raw material base, production and consumption of tin in Russia and in the subjects of the Far Eastern Federal District. It is established that in Russia there are sufficient reserves of tin, prospects for expanding its raw material base, developed and prepared deposits, but there is a problem of rational development of resources and production of final products. It has been determined that it is necessary to optimize the system of the tin industry. The need to develop intraregional use and processing of raw materials to the final product is shown. It is proposed to transfer the existing Novosibirsk tin plant to the territory of the Far Eastern Federal District or the organization of a new metallurgical enterprise in the territory of the Far Eastern Federal District. The results of the study can be useful for governments developing economic strategies for developing territories.

- Abstract:
- The article contains the results of the analysis of authoritative literary sources, which, together with the personal experience of the authors, made it possible to identify the most probable error limits in calculating the reserves of gold placer deposits. It was found that the exploration quality and the reliability of calculated reserves is a matter of concern for most companies involved in subsoil use, especially when purchasing new mining sites. It is shown that the proposed probable error limits are consistent with the presented examples of exploited gold placer deposits. The results of the research can help subsoil users and investors to more accurately assess their risks when choosing mining sites, which will create a more favorable investment climate.

- Abstract:
- The article presents the results of research on the options for choosing technologies for the development of the Kekura deposit, located in difficult operating conditions. It has been established that the deposit belongs to the group of complex structures and can be worked out by combining a traditional development system with filling the worked-out space with hardening mixtures with a new underground block leaching system. It is determined that the ores of the deposit meet the conditions of natural and resource-saving technology of leaching metals from rock ores according to most qualification requirements. It is shown that the study of the phenomenon of leaching metals from ores and detailing the methods of their implementation is still a little-used reserve for strengthening the raw material base of mining and processing enterprises due to the involvement in the production of all reserves of the deposit to radically reduce the ores and metals contained in them lost at all stages. It is revealed that when designing the technology for the development of reserves of the deposit, many years of experience in leaching gold, uranium, zinc, copper and other metals in underground blocks can be used. The results of the research can be useful in the refinement of already exploited and the development of new deposits, mainly of non-ferrous metals at enterprises of the extractive industries.

- Abstract:
- The article discusses various solutions for the production and transportation of high-paraffin oils of the Nenets аutonomous region, while methods of oil emulsification with water were given increased attention. As part of the work, studies of the physicochemical properties of oils and water-oil emulsions were carried out, the results of a study with the addition of polymers and surfactants to the water-oil mixture were presented. The high content of paraffin in oil (up to 30%) contributes to hydraulic losses, which complicates and increases the cost of its extraction, transportation and processing. In the course of the work, it was found that hydrotransport with the addition of polymers contributes to a significant reduction in viscosity, but the water-oil emulsion with the addition of a polymer is not sufficiently stable. As a result, non-ionic surfactants are added to help create an indestructible system for a long time. The research results showed that for the effective extraction of hard-to-recover oils, it is necessary to adapt classical and develop new technologies, and an individual approach helps to reduce hydraulic losses in the production of high-viscosity oils.

- Abstract:
- This article presents the results of many years of research on the stress-strain state of the reinforced concrete lining of an underground structure located at a depth of more than 1000 m. Monitoring was carried out using special measuring stations installed in the reinforcement and concrete of the lining. The operating stresses in the elements of the support of the general mine bunker are determined. Based on the results of field observations, a relationship was established between the distribution of stresses in reinforced concrete lining from time, depth of development and geological features of the location of the structure. The proposed method of geomechanical monitoring allows for a comprehensive assessment of the stress state of reinforced concrete structures for lining underground structures, the results obtained can be taken as a basis for designing such structures in similar mining and geological conditions.

- Abstract:
- The article presents the results of a character of variation stressed state in mine working after explosion blast-hole when the drifting method which were carried out in the industrial conditions when mine working «MGOK» drifting method of massive quartzite. Defined the diameters of blast-hole after explosion rising with 0,012 to 0,154 m. It is established that the stress state of the quartzite massif in the area of contouring boreholes in the center of the mine increases from 10.2 MPa to 57.8 MPa, which is explained by the formation of explosive residual stresses from the explosion of burncut and shoulder holes. According to the analytical formula developed for the quartzite array, calculations of the parameters of the stressed state of the array were performed. The results of the study of the nature of the change in the stress state of the blast hole rock mass after the blasting of tunneling holes can be directed to recommendations for safe mining during drilling and blasting of workings, and can also be useful in local determination of the degree of impact hazard of the blast hole part of the massif and the choice of methods for fixing workings.

- Abstract:
- The article presents the results of determining the subsidence of the Earth's surface based on the results of interferometric processing of space radar data from the Sentinel-1 satellite of the territory of Ridder Mining and Processing Division in 2021. It was found that the accuracy of determining the subsidence of the Earth's surface depends on the number of data and the presence of random, systematic, and gross errors for Sentinel-1 data. It is shown that with an increase in the number of interferograms, the accuracy of land surface subsidence detection increases up to a certain value. It is revealed that to achieve the highest accuracy of determining the annual mean subsidence velocities, at least 15 cycles of surveys per season should be carried out. The results of the research may be useful in determining the amount of data needed to perform interferometric processing of the results of space radar sounding.
