MANAGING SEISMIc RISkS IN MINES SHoRT couRSE

Dan Heal (ACG) and Marty Hudyma (Itasca Consulting Canada Inc.) will present a one-day short course to be held at Novotel Langley Hotel on Tuesday 6 November 2007 (see inside back page for more details).

SEMINAR THEMES PRE-SEMINAR EVENTS

As the mining industry matures in many regions of the world, its future becomes increasingly dependant on its ability to exploit deep mineral resources safely and efficiently.

As such, mining in a deep and high stress environment poses specific engineering challenges and, in some cases, elevated risks.

In 2002, the Australian Centre for Geomechanics initiated a very successful series of international seminars to provide a forum for the industry to share its experiences and knowledge of mining in deep and high stress conditions. The seminar series will continue to play an important role in disseminating new technologies and applications with the Deep and High Stress Mining 2007, to be held in Perth.

Deep and High Stress Mining 2007 is expected to see the launch of a new and comprehensive ACG reference book entitled “Challenges on Deep and High Stress Mining” encompassing the papers of the highest quality from the proceedings of seminars previously held in Perth (2002), Johannesburg (2004) and Quebec City (2006).
