The Carrapateena mine in South Australia is one of the largest copper reserves in Australia and the world, with an annual production rate of approximately 4,25 million tonnes.
The ore at Carrapateena is extracted using the sublevel caving mining technique, which is suitable for large orebodies with a steep dip, tabular or massive deposits, and continuation at depth.
A 5m diameter hole appeared at the surface in 2023.
As the hole continued to grow substantially over the next few months, monthly scanning became even more critical in order to assess its width and depth.
Carrapateena turned to Emesent and their autonomous Hovermap drone system, allowing surveying of the cave from a considerable distance, while at the same time ensuring the capture of precise and detailed information.
