Workshop Facilitator:

Johan Wesseloo

Associate Professor Johan Wesseloo
Principal Research Fellow — Rock Engineering
Project Leader — mXrap Development
Australian Centre for Geomechanics

Johan has been involved in geotechnical engineering since 1998, with experience in both underground and open pit environments. Johan obtained a BEng (Civil), MEng and PhD (Geotechnical) from The University of Pretoria, South Africa and is Fellow of the Southern African Institute of Mining and Metallurgy. He started his career as a geotechnical engineer with SRK Consulting, South Africa. In 2007, Johan joined the Australian Centre for Geomechanics, where he led and completed the ACG’s High Resolution Seismic Monitoring in Open Pit Mines project and the Mine Seismicity and Rockburst Risk Management. Johan has an interest in the rock engineering aspects of mine-induced seismicity and developed several procedures and methods for seismic analysis for rock engineering purposes and mining seismic hazard assessment methods, which are integrated into mXrap Apps.

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

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.

Open Pit Stream

Workshop Facilitator:

Professor Phil Dight – Open Pit Stream Facilitator
Professor of Geotechnical Engineering
Australian Centre for Geomechanics

Phil has been involved with the development and design of ground support for mining applications since 1975. Phil joined the ACG in 2008 and has since been working on stress memory effects in rocks, ground support applications, slope stability problems (including the use of microseismicity to understand failure mechanisms), and 3D rock properties. In 2017, Phil commenced a four year MRIWA project aimed at investigating the issues of strainburst vulnerability in underground mines.

Presenters include:

Michael Dunn

Evolution Mining Ltd

Michael has 25 years’ mining geotechnical engineering experience in operational, corporate and consulting roles. He has experience in South Africa, Australia, New Zealand, Indonesia, Ghana and the USA, covering a range of deep to near surface underground mining methods and small to large open pits. Michael has held several senior roles at AngloGold Ashanti, Newmont and SRK Consulting. In November 2015, he joined Evolution Mining as the Group Manager – Geotechnical and is responsible for providing geotechnical oversight and guidance for several underground and open pit operations and tailings storage facilities. Michael has a strong interest in the geotechnical design process, especially with respect to understanding geotechnical uncertainty and managing geotechnical risk. Michael is a Fellow and Chartered Professional of the AusIMM and has published 28 technical papers.

Alex Duran

Pells Sullivan Meynink

Coal mining in steeply dipping strata and managing risk”

Alex is a principal with PSM. Alex has been actively engaged in providing geotechnical advice to the open cut mining industry for over 30 years and has worked on a diverse range of projects both within Australia and overseas. Within the last 10 years, focus has been on providing advice to the coal sector for both dragline and truck /shovel operations. Part of this experience has been with steeply dipping strata, uncommon to Australia, and has brought a raft of challenges in design the slopes and managing the risk.

David Gaudreau

Newmont Mining Corporation

David has over two decades of mining, geotechnical and mine production management experience. He serviced sites and projects in Australia, Canada, Indonesia, China, Laos and India. He was involved in several projects spanning diverse geographical areas for surface and underground operations, ranging from conceptual studies to mine closure planning and execution. David has had leadership roles in mine operations management, geotechnical engineering, technical services management as well as consulting. He joined Newmont in September 2017 as Director Mining for the Australian region.

Paste & Tailings Stream

Workshop Facilitator:

Professor Andy Fourie – Paste and Tailings Stream Facilitator
Professor of Civil Environmental & Mining
The University of Western Australia

Andy Fourie is a Professor in the School of Civil, Environmental and Mining Engineering at the University of Western Australia in Perth.
He has Bachelors and Masters degrees from the University of the Witwatersrand in South Africa, and a PhD from Imperial College, University of London. He has worked at the University of Queensland, the University of Witwatersrand and has been a visiting professor at the University of Alberta, the Catholic University of Valparaiso in Chile and the University of Colorado in Boulder. His research is in the field of mitigating the impact of mining and municipal solid waste disposal. Outcomes from his research have been incorporated in changes to environmental legislation in South Africa. He has recently contributed to a series of Guidelines for managing mine tailings in Australia, as well as developing a document for the International Atomic Energy Association on barrier systems for retaining uranium mining waste.
