Abstract
In the current scenario, the aim of mining operations is to obtain as much usable ore as possible while maintaining a safe and profitable working environment. In open-pit mining and quarrying operations, the stability of slopes is of the utmost importance from both an economic and a safety standpoint. This is due to the fact that unstable slopes can lead to the loss of human life as well as damage to properties. Unmanned aerial vehicle (UAV) is an emerging technology in the field of geotechnical engineering, and its one-time procurement is sufficient for monitoring and management of large surface mines area. This paper discusses the challenges in implementing UAV technology for mine dump slopes, such as image acquisition, overlapping images, flying pattern, flying altitude, and ground control points (GCPs) acquisition, as well as the major problems involved in 3D dump slope reconstruction. The results show that UAV technology has the capability to deal with such a large structure as well as the importance of GCPs in improving the accuracy of the 3D model.
