RTK-UAV Laser Surveying Applied to Monitoring of Mine Residual Walls

The challenges of conducting mining operations in open-pit mines, especially while attempting to maintain a stable residual wall, crucially relate to ensuring the safety of miners and preserving the landscape. Currently, many mines monitor the displacement of the pointwise residual wall using APS and GPS with light wave rangefinders, but it is difficult to capture the areal behavior of the residual wall. However, issues persist such as equipment failure and the need for timely monitoring; thus, UAVs, which allow for highly accurate, safe, and efficient surveying, are being used. This study aims to develop a regular monitoring system, using RTK-UAV laser surveying, designed to ensure the safety of the residual wall slope.
