Since its inception the Centre for Excellence in Mining Innovation (CEMI) has worked closely with the mining industry to identify the challenges it faces in making deep mines safer and less risky. Efforts have focused on identifying knowledge and technology gaps in design and performance-related activities and on devising improvements aimed at addressing them. This paper will provide an overview of the progress to date – some five years after initiation of this effort. Tools and guidelines already made available to the industry through CEMI will be reviewed, and new ones currently being prepared will be highlighted. As well, state of the art rock mass monitoring research will be summarised as will results to date of a cross-disciplinary (mining and oil and gas industry) set of field trials being conducted by CEMI in Australia where fluid injection is being investigated as a means to re-distribute stress at a block scale in deep underground mines. This work, if successful, will mean that new tools and new approaches may be required for dealing with stress management in deep mines elsewhere, including in Canada. Finally, a new approach being led by CEMI to building database collection, integration and management capability within our industry will be highlighted.
