Analysis of Storage Capacity Change and Dam Failure Risk for Tailings Ponds Using WebGIS-Based UAV 3D Image

Tailings ponds, essential components of mining operations worldwide, present considerable potential hazards downstream in the event tailings dam failures. In recent years, instances failures, carrying environmental safety hazards, have occasionally occurred on a global scale due to limited technical approaches available for supervision ponds. this study, an innovative WebGIS-based unmanned aerial vehicle oblique photography (UAVOP) method was developed analyze storage capacity change and failure risk Its applicability then validated by deploying it at pond Yunfu City, Guangdong Province, China. The results showed that outcomes two phases real-scene 3D images met specified accuracy requirements with RSME 0.147–0.188 m plane 0.198–0.201 along elevation. capacities phase I II ponds were measured 204,798.63 m3 148,291.27 m3, respectively, 56,031.51 m3. Moreover, minimum flood control widths, free heights, slope ratios determined comply requirements, indicating low pond. This pilot case study demonstrated performance UAVOP evaluating It not only enhanced efficiency dynamic but also offered valuable references globally analogous research endeavors.
