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.

Australian Centre for Geomechanics team

Dr Dan Cumming-Potvin, Research Fellow and mXrap Project Lead

Daniel completed his Bachelor of Mining Engineering in 2012, graduating with first class honours from The University of Western Australia. Daniel has worked at a number of underground metal minces specialising in the areas of ground support, monitoring and mine seismicity. His PhD thesis, completed in 2018, is entitled ‘An extended conceptual model of caving mechanics’. In 2018, Daniel was appointed as project lead for the ‘Ground support guidelines for rockburst prone conditions’ sub-project of the Ground Support Systems Optimisation – Phase 2 project. In 2019, Dan joined the mXrap consortium full time as project lead.

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 and has since then been the MS-RAP and now the mXrap senior software engineer.

Paul graduated in 2000 from The University of Western Australia with a Bachelor of Electrical and Electronic Engineering (specialising in software) and is a member of the IEEE.  He developed custom software for clients in the mining industry before joining the ACG and starting work on MS-RAP version 1.

Paul has an interest in all things software and hardware, although his main interest is in C++ and performance Javascript at the desktop scale.

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.

Denisha Sewnun, Research Fellow

Denisha is currently working on the development of geotechnical 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 of experience in the rock mechanics aspects of open pit and underground mining projects. She has a BSc (honours) degree in Engineering Geology from the University of KwaZulu-Natal and a Master’s degree in Rock Engineering from the University of Witwatersrand. Denisha has recently joined the Australian Centre for Geomechanics as a Research Fellow after having spent the last 7 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.

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. He also performs geotechnical and mining-induced seismicity reviews providing him with the valuable opportunity to visit numerous operations worldwide. Johan was instrumental in the development of the mXrap software and many of the software routines and apps available in that platform. Johan is a Fellow of The Australian Institute of Mining and Metallurgy and the Southern African Institute of Mining and Metallurgy. He was awarded the SAIMM Gold medal in 2006 and 2016, and the SAIMM Silver Medal in 2014. In May 2019, Johan was appointed Centre Director.  

Stuart Tierney, Geotechnical Engineer

Stuart completed a Masters 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 our mXrap Consortium and is presently undertaking a PhD in geotechnical engineering.

Dr Kyle Woodward, Geotechnical Engineer

Kyle was initially associated with the ACG in 2011, through a final year research project for his undergraduate Bachelor of Engineering (Mining) degree.  With this work, he was focusing on the spatial analysis of seismicity associated with caving. Upon completion of his first degree at The University of Western Australia, Kyle performed his postgraduate research focusing on time-dependent seismic responses that are routinely observed for mining induced seismicity. He was awarded his PhD in late 2015.

Through his involvement with the ACG and the Mine Seismicity and Rockburst Risk Management project over the last 5 years, Kyle contributed to several of the standard ACG apps for the analysis of mining induced seismicity and since the acceptance of his thesis, has contributed to the development of several instrumentation apps currently in incubator and beta app stage.

Chun Ho, Software Engineer

Chun graduated in 2002 from the University of Western Australia in Electrical, Electronic Engineering and Computer Science and has been working in the software development industry since.

Chun contributes to mXrap on a part-time basis, under Paul’s direction, assisting in porting algorithms and libraries to mXrap Javascript and building associated apps.

UWA Students

Over the years, several postgraduate students were part of our team. These 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.
