Purpose. To study the modern methodology for forming a list of mineragenic factors and prospecting signs of ore fields and deposits of copper-porphyry type based on reference objects and model constructions on the example of deposits of Jungar-Balkhash folded region. Methodology. The methodology for identifying the desired factors and criteria is based on the collection and analysis of published and historical data, formation of digital databases using raster and vector geological maps. It also includes the use of modern, advanced specialized technologies and software packages for geophysical surveys and remote sensing data. According to the adopted technology, the results of aerospace methods are used, which include aerial photography, space radar imaging, infrared and spectrozonal surveys and others. The research involves interpretation of WorldView-3 satellite images. Findings. A list of metallogenic characteristics describing potential copper-porphyry mineralization within the study area has been compiled. Using the Spectral Evolution PSM-3500 infrared spectrometer, characteristic areas of secondary changes in copper-porphyry systems have been identified. ASTER spectral satellite radiometer data have identified mineral spectra, iron hydroxides, propylitic associations, areas of quartzite formation and silicification. By interpreting WorldView-3 satellite images, digital files have been obtained identifying iron ore minerals (hematite, goethite), secondary quartzites (advanced argillizites), varieties of sericite and other clay minerals, silicon, carbonates and propylites (chlorite, epidote). Based on interpretation, “parquet” fracturing in granite bodies and in the area of volcanogenic and sedimentary strata development has been identified, as well as structural lines indicating the strike of rock layers. Originality. Using the example of an exploration area based on the analysis of a priori and up-to-date data, the nature of a set of relevant criteria and signs for predicting and prospecting has been determined, aimed at increasing the reliability and accuracy of formation of geological-geophysical models. Practical value. The collected and systematized geophysical data can serve as a basis for developing plans for further geological exploration, identifying promising areas, determining the required volumes and methods of geophysical surveys. They can also contribute to the increase in estimate of reserves and production at mining sites. The prepared models are intended for preliminary assessment of known and newly discovered ore deposits of various types, as well as for determining the directions of geological exploration in the areas of prospecting the Northern Pribalkhash.

In recent years, the growing interest in new techniques for spatial data acquisition, processing and analysis has also found applications in surveying and geological departments, where it is used in the process of developing documentation. In the conditions of mining operations, surveying measurements must be carried out quickly, safely and with sufficient accuracy. The use of laser scanning allows the collection of a significant amount of data, which requires time-consuming processing, but is necessary for accurate modelling of objects in 3D. The legal basis for the use of laser scanning in mining is the acts that regulate activities in the field of surveying, geological survey documentation and technical standards for surveying. The process of implementing laser scanning in underground mining requires compliance with occupational safety regulations and technical standards, as well as proper training of personnel. The laser scanners used in practice are equipped with the SLAM algorithm, enabling precise measurement and point cloud generation. Appropriate software is crucial for processing and analysing the collected data. The use of laser scanning makes it possible to efficiently perform non-standard measurements, which contributes to streamlining work at mining facilities. However, to realize its full potential, it is necessary to train personnel and raise the level of use of this technology.

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.
