Simulation study demonstrates regression models predict rockfall impact energy and run-out distances in open pit mines, indicating potential for automated hazard assessment.
Key Points
Multi-linear regression accurately predicts impact kinetic energy, whereas multi-non-linear regression best models first impact position and final rockfall run-out.
Probabilistic rockfall simulations on 15 highwalls calibrated models using 4 walls and validated across 11 walls, extracting slope local roughness and angles.
3D photogrammetric models enable automated extraction of geometric profiles, highlighting a viable method for rapid rockfall hazard assessment across mines.
