PROVIDING STABILITY OF QUARRY SLOPES AT COMBINED MINING OF MINERAL DEPOSITS Khalidilla Rysbekov, M Nurpeisova, Kh. -K Kassymkanova, G Meirambek, D Kyrgizbayeva, et al. Naukovyi Visnyk Natsionalnoho Hirnychoho Universytetu, 2025 Purpose. To ensure the stability of quarry slopes during the combined development of mineral deposits by determining optimal slope parameters, ensuring their long-term stability while minimizing the volume of overburden operations, and reinforcing areas in case of detected fractures, both visible and hidden. Methodology. The study employs a comprehensive approach that includes field geomechanical observations, mathematical modeling, and analytical calculations. Modern geodetic methods, such as laser scanning and Global Positioning System (GPS) navigation, were applied to identify instability zones and assess the impact of geotechnical factors. The Examine2D software was used to model stress and deformation distribution within the rock mass. Findings. A zoning scheme of the stress-strain state of the rock mass was developed, taking into account the influence of tectonic faults and the load from waste dumps. Zones with low stability factor values (0.2–1.4), requiring additional reinforcement, were identified. Modeling showed that stress concentrations under the quarry bottom and near faults result in horizontal and vertical displacements of rock masses, affecting the stability of slopes and mining workings. Originality. For the first time, a comprehensive study of the stress-strain state of the rock mass under combined mining conditions in Kazakhstan was conducted using modern geodetic and geomechanical technologies. Key factors affecting slope stability and their long-term stability were identified. Practical value. The obtained results allow for the optimization of quarry slope parameters, a reduction in overburden operations, the prevention of emergency situations, the safe operation of underground workings, and improved mining efficiency. Recommendations for reinforcing unstable zones are provided.
Investigation of the rock mass state in the near-wall part of the quarry and its stability management Pavlo Saik, Kanay Rysbekov, Khaini-Kamal Kassymkanova, Vasyl Lozynskyi, Guldana Kyrgizbayeva, et al. Frontiers in Earth Science, 2024 Introduction: The research is aimed to identify the vulnerable areas of quarry slopes through the creation of a stress-strain state model for the rock mass at the Vostochny quarry, East Saryoba field of the Zhi-landy Group of cupriferous sandstones, as well as their subsequent strengthening.Methods: The research is based on the development of a database containing information on mining-geological, geophysical, geodetic and aerospace surveys. The authors of the research use modern geodetic, aerospace and geophysical technologies for scientifically based predicting of technogenic disasters and the rock mass stress-strain state modeling to ensure safe and optimal mining of fields in difficult mining-geological conditions.Results: The results obtained show that the strengthening of weakened quarry slopes based on the rock mass stress-strain state modeling contributes to the scientific-practical profitability of field mining and provides safe mining in difficult mining-geological conditions.Discussion: Novelty is in the scientific substantiation of the method for strengthening quarry slopes, which is based on the rock mass stress-strain state modeling. The research is of great practical importance, as the rock mass stress-strain state modeling increases the reliability of predicting the rock mass state during its mining. Strengthening of quarry slopes using the proposed method reduces risks and increases safety and economic efficiency of mining the solid mineral deposits in difficult mining-geological conditions.
GEOPHYSICAL STUDIES OF ROCK DISTORTION IN MINING OPERATIONS IN COMPLEX GEOLOGICAL CONDITIONS K.-K. Kassymkanova, K. B. Rysbekov, M. B. Nurpeissova, G. M. Kyrgizbayeva, B. B. Amralinova, et al. International Archives of the Photogrammetry Remote Sensing and Spatial Information Sciences ISPRS Archives, 2023 Geophysical methods of rock mass survey are one of the most effective ways of solving various problems in mining and are widely used in mining, gas and oil industries, as well as in science. They allow carrying out prospecting and evaluation works remotely, to reveal structural heterogeneities, cavities, contact zones of different media in rock mass with rather high accuracy. At the stage of designing a mining enterprise and making major decisions, it is necessary to have reliable information about the tectonic structure of the undermined and adjacent massif and parameters of its geodynamic activity. For this purpose, special studies of the tectonic structure of the rock massif must be carried out and the parameters of modern geodynamic movements must be determined. The most complete information about tectonic disturbances, identification of gliding surfaces, zones of macrofracturing are provided by geophysical methods of rock mass survey.In the article analysis of study of structural-tectonic structure of ore areas, separation and specification of ore-controlling structures, detection and depth mapping of ore-controlling faults, volume mapping of intrusive massifs based on previously conducted geophysical research in Zhezkazgan syncline area carried out. Geological and geophysical conditions of the central ore field (presence of rich bodies with high electric conductivity, considerable thicknesses of ore bodies, etc.) were favorable for application of various geophysical methods to search and trace rich ore bodies occurring at low depths.Moreover, possibilities of application of seismic works are considered at the solution of problems of ore geology in difficult mining-geological conditions of Kazakhstan.

Mining of Mineral Deposits, 2023 Purpose is to improve a geophysical method of determining the boundaries of ore-bearing rocks and tectonic disturbances under complex mining and geological conditions while developing 3D geological models. Methods. 3D geological models of natural objects were developed on the basis of complex structural, geological-geophysical, and lithological facies analysis with the wide use of modern 3D seismic exploration technologies taking into consideration the parameters for prediction and selection of optimal factors for ore deposit development. Findings. The scientifically substantiated result is represented by the increased reliability and efficiency of seismic exploration for singling out the ore horizons and ore bodies as well as tectonic disturbances at different depths by specifying geological structures of the prospective areas and sites under study. Originality. Basing on the carried out studies, methods of the development of 3D geological models to study depth geological inhomogeneities of the ore-bearing complexes under complex mining and geological conditions were improved. Practical implications. The obtained results of 3D modelling of geological media basing on the applied 3D seismic exploration will help increase a confidence factor of scientifically substantiated prediction of ore deposits, provide optimal development of complex ore objects, reduce risks, and increase economic efficiency of solid deposit development under complex mining and geological conditions.
