This article investigates the effectiveness of using Unmanned Aerial Vehicles (UAVs) and photogrammetry technology for monitoring the condition of open-pit mine slopes. Continuous monitoring of the geomechanical state of mine slopes is essential for ensuring operational safety and for the early detection of potential landslides and slope failures. In this study, high-resolution Digital Elevation Models (DEMs) and three-dimensional (3D) models of mine slopes were generated using aerial images acquired by UAVs. The obtained data were compared with conventional geodetic monitoring methods to evaluate monitoring accuracy, time efficiency, occupational safety, and economic performance. The results demonstrate that UAV-based photogrammetry enables rapid detection of slope deformations, effective mapping of hazardous zones, and improved operational efficiency of monitoring activities. Furthermore, the application of this technology significantly reduces field survey time and associated costs while minimizing risks related to human involvement in hazardous areas. The findings provide a scientific basis for improving geotechnical monitoring systems in open-pit mines and for developing practical recommendations aimed at enhancing mining safety and slope stability management.
