- Increasing use of technology to monitor tailings dams
Technology has a vital role in strengthening the monitoring of our tailings facilities. A particular focus is the increasing use of drones to monitor environmental and critical controls, and to document inspections through photographs and video.
At Impala Rustenburg, for example, where there are two tailings dams (one active with 328 million m3 impoundments) we conduct monitoring (CCTV) inspections and volumetric surveys via drone. All these initiatives are conducted through a third party.
Advantages of using drone survey/inspections instead of the previously deployed visual helicopter flights, include:
The drone survey/inspection flights can be carried out at any given point if the need arises, thus giving more of a “live” monitoring method of TSF deposition.
