Associate Professor Johan Wesseloo

Principal Research Fellow — Rock Engineering
Project Leader — mXrap Development
Australian Centre for Geomechanics

Johan has been involved in geotechnical engineering in the mining industry since 1998, with project experience that includes both underground and open pit environments. He obtained a BEng (Civil), MEng (Geotechnical) and PhD (Geotechnical) from The University of Pretoria, South Africa and is Fellow of the Southern African and The Australian Institutes of Mining and Metallurgy. He started his career as a geotechnical engineer with SRK Consulting, South Africa in 1998 and joined the ACG in 2007. Johan has an interest in the rock engineering aspects of mine induced seismicity and has developed several procedures and methods for seismic analysis for rock engineering purposes and mining seismic hazard assessment methods; featured in the ACG software mXrap. Johan has also contributed to the field of risk-based design in mining rock slope engineering and underground environments.

Presenters Include:

Dr Stephan Arndt

Portfolio Senior Technical Manager, GEOVIA
Dassault Systèmes , Australia

Stephan has over 25 years’ experience in advanced simulation methods in applications of rock mechanics, seismicity, discrete fracture networks, coupled multi-physics simulations, fracture mechanics and constitutive models. His research interests include emerging technologies in geomechanics; cross-industry synergies; scalability of modelling methods; integration of machine learning and optimisation; better quantification of risk under uncertainty; and using high performance computing, visualisation and virtual reality in decision making. Stephan has extensive consulting experience in the mining sector consulting for major mining projects in Australia and overseas.
