Mining induced seismicity can expose tailings dams to ground motions with potential to trigger a failure, if the structure reaches a certain level of vibrations that could exceed the seismic coefficient design criteria from pseudostatic analysis. Des

Advanced tailings dam performance monitoring with seismic noise and stress models

Autor: Susanne Ouellet, Jan Dettmer, Gerrit Olivier, Tjaart de Wit, Matthew Lato

Tailings dams retain the waste by-products of mining operations and are amongst the world’s largest engineered structures. Recent tailings dam failures highlight important gaps in current monitoring methods and a pressing need to advance research o

The Role of Passive Seismic Imaging in Near-Mine Exploration

Autor: Gerrit Olivier, Andrew Foley, Nicola Ramm, Philippe Dales, Tjaart de Wit, Francois Malan, Olaf Goldbach

The future of the mineral mining industry relies on the ongoing success of exploration projects. In this paper, the use of near-mine passive seismic imaging is discussed as a solution to exploration demands. We explore the issues currently being face
