In cooperation with the Wits mining institute in South Africa, a PhD student of the ComNets department, Idrees Zaman, is working on a system which assists miners by providing information about possible threats and supporting rescue staff to locate miners who have become lost in case of a disaster. The system is based on a wireless underground sensor network which is under development at the ComNets department. There is an article about the project in the South African newspaper "Sowetan" and a video by Wits university available on Youtube.
