Relevance. Rock mass cracks are fracture surfaces in rocks with no signs of shifting. They significantly affect the physical and mechanical properties of rocks, and they, in turn, must be taken into account when planning mining operations and constructing mining structures. This problem can be solved by applying artificial intelligence (AI) methods, as they are able to process large amounts of data. The purpose of the work: choice of artificial intelligence method for detecting rock mass cracks from GPR data based on an analytical review of the applied artificial intelligence methods in the processing and interpretation of geophysical measurement data. Research methodology: analytical review of the application of artificial intelligence methods in the processing of geophysical methods data. The results of the work and their scope. As a result of the study, a table has been formed showing the qualitative assessments of the four characteristics of AI methods, which make it possible to make a reasonable choice of a method for detecting rock mass cracks from GPR data. The resulting estimates of the characteristics of AI methods will be useful to a wide range of geophysicists involved in data processing and interpretation and those who want to improve the efficiency of their work. Conclusions. The review showed that artificial intelligence methods are widely used in the processing of geophysical methods data. Among the methods used, one can single out artificial neural networks, support and relevance vector machines, genetic algorithms, etc. A convolutional neural network was chosen as an artificial intelligence method for detecting rock mass cracks from GPR data, since it is most sensitive to that data type and has a high noise immunity.

The study deals with the history of exploration of the subsoil resources of the Sakha Republic (Yakutia), its huge and diverse geological and mineralogical potential. The authors analyse the existing museums devoted to geology and mineralogy, and put forward the idea of the necessity to create a large museum reflecting the history of geological exploration and development of mineral resources in the republic. The urgent need to create a mining and geological museum in Yakutsk, reflecting the history of geological exploration and development of mineral resources in the republic is emphasised. The concept of the museum as a powerful centre of scientific and educational education and a space of cultural exchange of society, based on axiological basis, is defined. Its mission as propaganda and popularisation of knowledge about the Earth, preservation of unique geological fund of the republic, orientation and self-identification of the person in the world of values is characterized.

In this article, we propose a way to replace test pits in the exploration of placer deposits of the cryolithozone. The idea is to take an additional volume of samples from a pre-drilled exploration well by expanding its trunk in a given interval using a specially designed and patented device for local expansion of the borehole section (Patent for Invention N 2792482 dated November 15, 2022). Thus, by using a drilling expander, it is possible to obtain an additional volume of samples from the well, while the well expansion is performed only in a certain area of the well. If the diameter of the well expansion is 1300 mm or more, then using an expander will allow extracting from a given well interval the same volume of samples that is obtained during the construction of a test pit. This method will make it possible to replace construction of a test pit in the exploration of placer deposits of the cryolithozone, which are characterized by a high proportion of manual labor and require significant financial resources and time.

The article considers the distribution of unique lakes in the territory of Yakutia. The Republic of Sakha (Yakutia) is one of the most lake regions in Russia. Since 1978, the Laboratory of Lake Science of the Yakut State University, later North-Eastern Federal University, has been engaged in scientific research of the lakes of Yakutia for many years under the scienti c supervision of the famous geographer-limnologist, Ph.D., Professor I. I. Zhirkov, which is known among lake scientists of Russia and the world as the Yakut school of Limnology. As a result, a landscape-limnogenetic classification of lakes by types of basin origin was compiled, hydrological and morphometric parameters were identified, lake resources were determined, including “unique lakes”. Unique lakes are a group of specially protected lakes that represent great economic, social and aesthetic value for current and future generations. The list of 26 unique lakes was determined by Decree of the President of the RS (Ya) dated 08/16/2004 N 836. The unique lakes of Yakutia are mainly considered in the ecological aspect as specially protected natural objects. The relevance of this article lies in the geographical approach to identify the uniqueness, natural features of the unique lakes of Yakutia. A comprehensive geographical description provides a general physical and geographical characteristic of each unique lake, depending on its geographical location, natural features, accessibility, natural and economic significance for the economy, population, conservation status, etc. The landscape approach to the spatial analysis of the distribution of lakes was reflected in the consideration of the distribution of unique lakes across the physico-geographical provinces of Yakutia.

The Gross mining and processing plant under reconstruction is located in southwestern Yakutia, within a territory classified as earthquake-prone. According to the OSR 2015 map with indices A, B, C, the seismicity of the construction area is 9, 9 and 10 points MSK-64 scale, respectively. Despite significant research experience in clarifying the general seismic zoning, the issues of interpreting the source materials, as well as the results obtained, may be ambiguous. In confirmation of this, it can be noted that over the past 25 years four generations of general seismic zoning maps (OSR 97, OSR 2012, OSR 2015, OSR 2016) followed one another. The relevance of research is determined not only by the seismic safety of construction projects, but also by their economic component. Thus, 1-point seismic hazard increase entails 13% to 20% construction cost increase. The aim of the research is to specify the level of baseline seismicity for survey areas using the methodology of probabilistic seismic hazard analysis with respect to the regional seismotectonic conditions of the Gross mining and processing plant construction area. As a result of the analysis of materials from geodynamic active neotectonic zones, the presence of active structures capable of generating earthquakes with magnitudes М = 6.5 - 7.0 was established. A probabilistic assessment of the parameters of seismic impacts was carried out: macroseismic intensity (in MSK-64 points), peak accelerations and response spectra, for the case of earthquakes of the maximum possible magnitude Mmax, at the minimum possible distance R from the study area of the projected construction of objects, was carried out using the EAST-2016 software. The specified level of seismic hazard for return periods of 500, 1000 and 5000 years are I = 8, I = 8.3 and 9.1 points MSK-64 scale, respectively.

Currently, the scienti c community faces the task of identifying and minimizing the negative impact on the natural environment and related environmental risks caused by the impact on ecosystems, especially anthropogenic factors related environmental risks. The determining role in the assessment of environmental risk is to determine the probability of occurrence of effects of different nature in ecosystems because of anthropogenic factors and to take measures to prevent their negative impact. The purpose of the presented theoretical study was to study and analyze the principle of system-wide methodology of quantitative assessment of biogeocenosis quality within the boundaries of anthropogenic in uence on the sustainability of industrially developed territory. The considered principle can provide prerequisites for making changes in the norms of nature management in Russia.
