Australian Centre for Geomechanics team
The Australian Centre for Geomechanics (ACG) has had a long involvement in the development of mXrap under its Mine Seismicity and Rockburst Risk Management research project. ACG continues to be involved in the further development of mXrap under the umbrella of the mXrap Consortium.
Dr Dan Cumming-Potvin, Project Lead – mXrap development
Dan completed his Bachelor of Mining Engineering and PhD at The University of Western Australia in 2012 and 2018, respectively. He has worked at a number of underground metal mines in Australia, specialising in the areas of ground support, monitoring, and mine seismicity. Dan is project lead for mXrap.
Paul Harris, Senior Software Engineer
Paul was originally contracted in 2001 to develop the software component of the Mine Seismicity and Rockburst Risk Management Project. Before joining the ACG, he developed custom software for clients in the mining industry. Paul is now continuing to develop the mXrap software, and is the project manager and developer for the Regional Seismic Network project. His focus is on software development and its application to mining and seismicity.
Dr Matthew Heinsen Egan, Software Engineer
Matthew joined the ACG in 2018 as a software engineer. Matthew’s focus is on further developing the libraries and tools available for mXrap App developers, and contributing to the development of specific mXrap Apps.
Joseph Justin Muaka Mbenza, Research Fellow
Joseph joined the ACG in 2019 as a research fellow. His areas of interest include: advanced numerical modelling and statistical, probability and data analysis. Previously, Joseph was a senior mining geotechnical engineer for SRK Consulting (South Africa) (Pty) Ltd. He has 15 years of experience in mining and rock mechanics.
Joseph has a bachelor’s degree in mining engineering from University of Lubumbashi, Democratic Republic of the Congo, and a master’s degree in Rock Engineering from the University of the Witwatersrand, South Africa. He was the recipient of the Rauji Foundation award in 2004 for best student, Faculty of Engineering, University of Lubumbashi, and the Chairman award for employee of the year at SRK Consulting (South Africa) (Pty) Ltd in 2016.
Denisha Sewnun, Research Fellow
Denisha is currently working on the development of geotechnical borehole data analysis apps and is involved in the DFN/block model limit equilibrium ground support design tools research project.
Denisha has more than 10 years’ experience in the rock mechanics aspects of open pit and underground mining projects. She has a bachelor’s degree (honours) in engineering geology from the University of KwaZulu-Natal and a master’s degree in rock engineering from the University of the Witwatersrand. In 2020, Denisha joined the ACG as a research fellow after having spent the last seven years providing consulting services for mining projects across Africa. Her principal areas of expertise include geotechnical data analysis, geotechnical investigations, three-dimensional geotechnical block modelling and rock support design.
Dr Kyle Woodward, Research Fellow
Kyle was initially associated with the ACG in 2010 through his final year research project for his undergraduate Bachelor of Engineering (Mining) degree at The University of Western Australia. Upon completion of this degree, Kyle undertook postgraduate research with the ACG which focused on time-dependent seismic responses to mining. In late 2015, he was awarded a PhD (Civil and Resource Engineering) for his thesis entitled ‘Identification and Delineation of Mining Induced Seismic Responses’. Kyle has been involved in various ACG projects including the Mine Seismicity and Rockburst Risk Management project and the mXrap Consortium. Kyle was project leader for the ACG Stope Reconciliation and Optimisation Research project from 2016 to 2019. He is currently working on Phase 2 of this research project along with work associated with the mXrap Consortium.
Liam Niedzielski, Software Engineer
Liam completed his Bachelor of Science in Physics and Computer Science at The University of Western Australia in 2021. He joined the ACG at the end of 2021 as a software engineer on the mXrap development team. Liam works alongside the geotechnical engineers to develop and maintain mXrap apps, as well as contribute to the libraries available for mXrap developers.
Part-time team members
Associate Professor Johan Wesseloo, Australian Centre for Geomechanics Director
Since obtaining a BEng (Civil) and MEng (Geotechnical) from The University of Pretoria, Johan has been involved in geotechnical engineering in open pit and underground environments throughout 14 countries. He commenced his career in 1998 as a geotechnical engineer at SRK Consulting in Johannesburg where his experience included open pit and underground projects in varying geotechnical conditions. In 2005 he was awarded a PhD (Geotechnical) from The University of Pretoria. Johan joined the ACG in 2007 as a research fellow. During his time at the ACG, Johan has been involved in research, the supervision of postgraduate students and geotechnical training and was instrumental in the development of the mXrap software. In 2019, Johan was appointed centre director. Johan is a fellow of AusIMM and the SAIMM and was awarded the SAIMM Silver medal in 2014 and the Gold medal in 2006 and 2016 and 2020.
Stuart Tierney, Geotechnical Engineer
Stuart completed a Master of Engineering Science (mining geomechanics) at Curtin University in 2016 where his thesis in the final semester was assisted by the ACG. In February 2017 he joined the ACG as a research assistant for the mXrap Consortium and is presently undertaking a PhD in geomechanics engineering at The University of Western Australia.
Over the years, several postgraduate students have been part of our team. Students form a valuable part of the team as they contribute to research and development and also help out with the mXrap development. As part of their studies, they also develop software routines and mXrap Apps, some of which have matured to standard ACG apps.
