Dyachkov B. A. New data on non-traditional types of East Kazakhstan rare metal ore [Електронний ресурс] / B. A. Dyachkov, S. S. Aitbayeva, M. A. Mizernaya, B. B. Amralinova, A. E. Bissatova // Науковий вісник Національного гірничого університету. - 2020. - № 4. - С. 11-16. - Режим доступу: http://nbuv.gov.ua/UJRN/Nvngu_2020_4_4 Purpose. Studying the patterns of formation and assessing the prospects of non-traditional types of rare-metal mineralization in East Kazakhstan. Methodology. Analysis of literary and funds materials; conducting field research on typical objects; sample selection; conducting of isotope research on typical objects; ICP-MS - Agilent 7500cx mass spectrometric analysis, microprobe analysis using a JSM 6390LV scanning electron microscope with an energy dispersive attachment, X-ray diffraction analysis - CPB-1M, silicate chemical analysis. Findings. A new non-traditional "non-pegmatite" type of rare-metal mineralization of predominantly lithium specialization associated with small intrusions and dikes of the kunush complex and albitized and greisenized granites (apogranites) is substantiated. Originality. A geological and genetic model of rare metal ore formation has been developed, reflecting the superimposition of rare metals (Sn, W, Li, etc.) on earlier small intrusions of plagiogranites of the kunush complex (C3), susceptible to contact-metasomatic transformations under the influence of rare-metal granites of the Kalba complex (P1). The prospects of an independent "non-pegmatite" type of tin-tantalum-lithium mineralization are substantiated. Practical value. The results of the research are aimed at strengthening the mineral resource base as an additional source of rare metals for existing enterprises in East Kazakhstan. | ||

Amralinova B. B. Mineralization of rare metals in the lakes of East Kazakhstan [Електронний ресурс] / B. B. Amralinova, O. V. Frolova, I. E. Mataibaeva, B. B. Agaliyeva, S. V. Khromykh // Naukovyi visnyk Natsionalnoho Hirnychoho Universytetu. - 2021. - № 5. - С. 16-21. - Режим доступу: http://nbuv.gov.ua/UJRN/Nvngu_2021_5_5 Purpose. Study on the chemical composition of lake waters, salt brines, brine and bottom sediments to identify the mineralization of rare metals and other types of minerals. Methodology. Mass spectrometric studies (mass spectrometer with inductively coupled plasma ICP-MS 7500cx from AgilentTechnologies) for the purpose of high-precision analytical studies on the chemical composition of salt lake water in order to assess the content of rare elements. The use of unmanned aerial vehicles for linking and geometrizing lakes. Findings. Field surveys on the geometrization and linking of lakes were carried out. From the materials obtained with the help of the drone, orthophotoplans were created (with a measurement accuracy of up to 1 centimeter), as well as a digital terrain model and a digital terrain model. A complex of analytical works was carried out using inductively coupled plasma spectrometry. When analyzing the distribution graphs of the absolute content of micro-components in the waters of the lakes of the Delbegeteysky massif, it was found that all samples were enriched with sodium, phosphorus, iron, magnesium and barium. The results of the analyses revealed the predominance of sulfates and chlorides in the composition of the surface waters of most of the water bodies of the Delbegeteysky massif. At the Burabai site, lake waters are characterized by an alkaline reaction of the environment (on average pH 8,71). At the same time, the salinity of water bodies varies from 05 to 9 g/dm<^>3 | ||

Sailygarayeva M. Predicting of vertical displacements of structures of engineering buildings and facilities [Електронний ресурс] / M. Sailygarayeva, A. Nurlan, K. Rysbekov, S. Soltabayeva, B. Amralinova, Zh. Baygurin // Naukovyi visnyk Natsionalnoho Hirnychoho Universytetu. - 2023. - № 2. - С. 77-83. - Режим доступу: http://nbuv.gov.ua/UJRN/Nvngu_2023_2_14 Purpose. The research is aimed at solving the tasks of monitoring and assessing the state of an engineering object and determining predictive characteristics in the form of construction of various models of settlement and deformation of a structure based on the results of geodetic measurements, taking into account the space-time interaction of engineering objects with the geological environment in a seismic zone with the earthquake energy class values of K = 6 - 7,5, in the area of possible underground fluctuations with an intensity of 3 - 4 points. Methodology. An analytical methodology has been developed that takes into account the geological conditions of the foundation, changes in the groundwater level, soil compaction under significant static load, as well as the accumulation of damage in the supporting structures caused by the impact of numerous and insignificant underground seismic shocks, for predicting the vertical displacements of the engineering facility supporting structures. To assess the durability and stability of design components, the least squares method is used, which makes it possible to display the patterns of deformation process development. Obtaining new results during the period of further operation in order to draw up a technical conclusion on the state of the facility and its stability is possible by monitoring and predicting deformation deviations of individual components of an engineering object in the vertical plane. Findings. With the help of mathematical modeling of strength calculations of supporting structures based on geodetic measurement data, it is possible to determine the quantitative characteristics and patterns of deformation process development during the engineering facility operation. The performed calculations on mathematical modeling make it possible to reveal the distribution of the parameters of amplitude-frequency characteristics of the linearly deformable monolithic plate upper layer along the perimeter and to predict possible deformation changes over a certain period of time during the engineering facility operation. According to the executive survey data, vertical deviations of structures along the facility perimeter AB, BC, CD, DA have been determined in the range from 1 to 27 mm, which is the basis for predicting deformation deviations in the vertical plane. In addition, as a result of engineering-geological surveys conducted on the building construction site, the geological-lithological structure of the site has been determined. Originality. A methodology for predicting the deformation processes of individual sections of vertical structures and monolithic walls of an engineering facility, which are associated with the complex lithological structure of the foundation section and the location of the object in a seismically hazardous zone, is proposed. | ||
