Abstract
Open-pit slope stability is one of the key factors determining the safety and efficiency of open-pit mining operations. With increasing pit depth, growing complexity of rock mass structure, and intensification of mining activities, the need for advanced methods for studying slope stability based on digital technologies is steadily increasing. The aim of this study is to systematize and comparatively analyze modern methods for investigating open-pit slope stability, taking into account their capabilities and limitations under mining conditions. The paper presents an analytical review of computational geomechanical approaches, geodetic instrumental methods, terrestrial laser scanning, UAV-based photogrammetry, and satellite radar interferometry (InSAR). A comparative analysis of these methods is performed based on key parameters, including data type, spatial coverage, and capabilities for deformation analysis. The results show that each method has specific advantages and limitations related to data characteristics, observation conditions, and analytical potential. It is established that none of the methods, when used individually, provides a complete and reliable description of slope stability. The highest level of informativeness is achieved through the integration of different methods within comprehensive analytical approaches. The results of this study provide a systematic understanding of the role of modern digital methods in slope stability research and confirm the перспективность of developing integrated digital systems for monitoring and assessing open-pit slope stability.
