Digital photogrammetry has emerged as a prevalent, widely adopted, and popular technique for mapping and modeling geological features, as well as for the characterization of rock masses in mining operations. Despite the utilization of ground-based photogrammetry methods, the persistent challenge of capturing geological and structural data in remote mining regions remains, leading to incomplete geotechnical models of mines and geomechanical mining databases. The lack of comprehensive data acquisition in inaccessible areas can have significant consequences, such as the potential for major collapses in massive underground excavations, including extraction stopes.
The kinematic analysis of a region's discontinuities can serve as a valuable tool for predicting potential failures by addressing the gaps in geotechnical data acquisition in inaccessible areas. The practical implementation and ease of use of unmanned aerial vehicles (UAVs) or drones in underground mines, coupled with recent advancements in obstacle detection systems, have facilitated precise photogrammetric surveys in mining environments. These technological advancements have enabled the collection of high-resolution imagery and accurate topographic data, even in challenging mining conditions.
The modeling of jointed rock masses has long been a focal point for geomechanics specialists and rock mechanics engineers, given the direct influence of a comprehensive understanding of rock masses on design, mining geometry, and maintenance systems. This review study initially underscores the significance of investigating jointed rock masses and elucidates the factors influencing their formation mechanisms, including geological structures, tectonic forces, and weathering processes. By examining these factors, researchers can develop more accurate models of jointed rock masses, which can inform decision-making in mining operations.
The study then presents case studies of modeling jointed rock masses using aerial data collected via drones, highlighting the potential of this technology for enhancing the accuracy and efficiency of geotechnical data acquisition. The use of drones in data collection offers several advantages, including reduced costs, increased safety, and the ability to collect data in challenging environments. However, the challenges of utilizing various drones in the mining industry for future studies should not be overlooked. These challenges include the need for specialized training, regulatory compliance, and the development of robust data processing and analysis protocols. By addressing these challenges, researchers can fully leverage the potential of digital photogrammetry and drone technology for geotechnical modeling and mining operations.
