Cavity Scanning in Mining using Hybrid Seismic Interferometry

Summary The hybrid seismic approach, using generated surface waves, enables early detection of subsurface cavities, supporting proactive risk mitigation in mining. It provides high-resolution shear-wave velocity (Vs) models, allowing precise identification of weak or unstable zones. The method reduces acquisition and processing time, improving operational efficiency in active mining environments. It eliminates the need for long recording periods and complex source synchronization, simplifying field logistics. The approach is adaptable to dynamic and space-constrained mining sites, making it practical for continuous monitoring. It integrates easily with existing geotechnical monitoring systems, enhancing overall hazard detection capabilities. Early and accurate imaging of subsurface anomalies helps prevent surface failures and supports safer mine planning. The hybrid method improves both vertical and lateral resolution, outperforming traditional seismic techniques. By enabling rapid, detailed assessments, it aids informed decision-making for geohazard management. This technique strengthens short- and medium-term monitoring strategies, contributing to safer and more resilient mining operations.
