Contenido Deep Mining 2014.Proceedings of the Seventh International Seminar on Deep and High Stress Mining

The objective of this series of international seminars is to promote discussion and documentation of the latest technologies and practices of mining in deep and high stress environment. Since inception, the technical content has focussed on geomechanics issues with themes such as seismic monitoring, ground support and numerical modelling
dominating the proceedings. Nevertheless, the seminars also offer an important contribution to the more traditional mine engineering themes of deep mine planning and design, as well as ventilation.
Deep Mining 2014 followed the previous International Deep and High Stress Mining Seminars held in Perth, 2012; Santiago, 2010; Perth, 2007; Quebec City, 2006; Johannesburg, 2004; and Perth, 2002

Keynote authors:

• David Counter, Glencore Canada Corp., Canada

• Professor Ray Durrheim, University of the Witwatersrand and CSIR, South Africa

• Dr Stephen Hardcastle, Natural Resources Canada, Minerals and Metals Sector,       CanmetMINING, Canada

Content:

• Case studies
• Ground support
• Numerical modelling
