JOHANNESBURG (miningweekly.com) – University of Cape Town (UCT) PhD graduate Dr Jeanine Engelbrecht has asserted in her thesis that microwave imagery captured from earth-orbiting satellites is able to measure deformation caused by underground mining.

“Surface deformation owing to underground mining poses risks to health and safety as well as infrastructure and the environment. The information, derived from the analysis of microwave data, will be useful for long-term monitoring efforts to guide future development planning and subsidence risk assessment,” she commented.

According to Engelbrecht’s research, satellite-based sensors could be used for remote detection and the monitoring of surface subsidence, contrasting with traditional field-based measurements, which were point-based and did not “understand” the full extent of deforming areas.
