Apart from the current team members which you can view here, the contribution of the following people is gratefully acknowledged.

Gerhard Morkel

Gerhard joined the ACG in 2014 as a research engineer for the ACG’s Mine Seismicity and Rockburst Risk Management project. He became invaluable to the mXrap consortium during it’s first cycle, eventually becoming mXrap project lead before leaving the ACG in late 2019. His work had a significant impact on many mXrap apps, particularly the Seismic Event Quality, Strong Ground Motion and Caving Draw Column Height apps. He is currently working on a PhD with the ACG investigating seismic event quality.

Professor Yves Potvin

Yves joined the Australian Centre for Geomechanics at The University of Western Australia in 1998 and was appointed Centre Director in 2000.  Yves has played an invaluable role in the development of mXrap through his guidance and support since the first version of MS-RAP saw the light; a role he is still continuing. Find out more about Yves here.

Associate Professor Marty Hudyma

From 1999 to 2006, Marty was the project leader of Phases I and II of the ACG’s Mine Seismicity and Rockburst Risk Management Project. During these years his work and ideas shaped the development of MS-RAP. Marty undertook his PhD on the analysis and interpretation of clusters of seismic events in mines, and his work has influenced and shaped the approach to the management of mine induced seismicity.

Doctor Daniel Heal

From 2006 to 2008, Dan lead the ACG’s Mine Seismicity and Rockburst Risk Management Project. Dan focussed on the problem of quantifying and managing rockburst damage and during his PhD studies developed the Rockburst Damage Potential.  This work formed an important component of MS-RAP v3 and has impacted greatly on industry.

Wei Duan

Wei joined the ACG in 2012 as a research assistant with the Mine Seismicity and Rockburst Risk Management project and completed his Master’s Degree in Geomechanics under the supervision of Prof. Johan Wesseloo and Prof.  Yves Potvin. Wei’s research was a continuation of previous work done by Dr. Daniel Heal on empirically assessing the vulnerability of underground excavations in rockbursting conditions.  Through his involvement with the ACG and the Mine Seismicity and Rockburst Risk Management project, Wei contributed to the standard ACG apps for the analysis of mining induced seismicity.

Johan Grobler

Johan finished his Bachelors degree in Mining Engineering at The University of Western Australia in 2015 and has completed his undergraduate thesis under the guidance and supervision of ACG team members Johan Wesseloo and Gerhard Morkel. Johan gained employment at the ACG in the beginning of 2016 as a research assistant under the mXrap project. In this role, he was involved in the implementation of an mXrap Rockburst Damage Potential model for the Golden Grove underground hard rock metal mine in Western Australia. He has also assisted the mXrap team in app development, most recently focussing on the development of a LiDAR application which uses LiDAR points clouds to analyse closure in mine drives.
