ACG INTRODUCTION TO THE APPLICATION OF RISK-BASED METHODS IN UNDERGROUND MINING GEOMECHANICS WORKSHOP

THIS EVENT HAS BEEN POSTPONED - STAY TUNED FOR UPDATES ON NEW DATE.

Safety, financial, environmental and other risks need to be continually managed in the mining industry and many different techniques are employed to do this. Design and planning decisions, however, are not always based on risk and the risks are not always quantified, which may lead to missed opportunities and suboptimal solutions.

The aim of this ACG workshop is to provide a forum for underground mine operators to discuss quantitative risk-based design and decision-making in an underground environment.

PRESENTERSAssociate Professor Johan WesselooDirector, Australian Centre for GeomechanicsJohan joined the ACG in 2007 as a Research Fellow and was involved in research, supervision of postgraduate students and geotechnical training. Johan led the development of the mXrap software and many of the software routines and apps available in that platform. In 2019, Johan was appointed Centre Director.
