W1: Introduction to the Application of Risk-based Methods in Underground Mining Geomechanics Workshop

Workshop Overview:

Within the mining community, geotechnical risk is often under-appreciated, sometimes ignored and seldom properly quantified. In all areas of geomechanics, the uncertainty and variability that engineers need to deal with necessitate a rigorous process of quantification or, in the very least, robustly qualifying likelihoods and consequences.

There appears also to be a large gap between the state-of-the-art and the state of general practice when it comes to the qualification and quantification of geotechnical risk.

The aim of this ACG workshop is to provide a forum for underground mine practitioners to familiarise themselves with the risk-based design methods.

Topics include:

  • Probability, risk and design
  • Calculation techniques for performing probabilistic calculations
  • Underground applications of risk-based design
  • Application of probabilistic methods with numerical modeling


Workshop Presenters:

Associate Professor Johan Wesseloo, Director, Australian Centre for Geomechanics

Johan 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 May 2019, Johan was appointed Centre Director

William Joughin, Chairman, SRK Consulting (South Africa) (Pty) Ltd.

William spent the past 28 years in underground rock engineering, working on South African deep-level gold mines before joining SRK Consulting in 1998. He specialises in underground rock engineering investigation and design, with expertise in numerical modeling, selecting mining methods, designing excavations, investigating shaft stability and geotechnical risk, while providing consultancy services for mining projects on six continents.

Joseph Mbenza, Research Fellow, Australian Centre for Geomechanics

Joseph has 14 years of experience in mining and rock mechanics. He has a BSc Eng from University of Lubumbashi in the Democratic Republic of the Congo (DRC) and a Master’s degree in Rock Engineering from University of the Witwatersrand in South Africa. He is the recipient of the Rauji Foundation award in 2004 for best student at the faculty of engineering of the University of Lubumbashi and the Chairman award for the employee of the year at SRK South Africa in 2016.
