The Static Liquefaction Workshop will be held in person and online via Zoom, enabling participation from anywhere in the world.
This workshop aims to provide demonstrations of the static liquefaction failure mechanisms (and triggering process) as it relates to tailings, and the tools used to assess the potential for this behaviour.
This will be achieved through explanation on the use and interpretation of the cone penetration test (CPT); the key tool to assessing the strength and liquefaction susceptibility. Theoretical discussions will be alternated with examples from various tailings failure case histories to highlight the relevance of the concepts and the meaning of the results.
Mining and tailings consultants, operators of tailings storage facilities, as well as regulators will find this workshop of interest.
Day 1 topics:
- Relevant soil mechanics review
- Case histories
- In situ testing
Day 2 topics:
- Stability analysis considerations
- Laboratory testing and static liquefaction demonstration
- Insights from TAILLIQ – lab testing methods and CPT interpretation
Feedback from past Static Liquefaction Workshop attendees:
“Definitely valuable to the industry, and better understanding on how the different testing, sampling, analysis work.”
“I think that presented content was excellent.”
“It has been relevant to my background, work requirements and current trend in the industry.”
|Professor Andy Fourie
Professor of Civil and Mining Engineering
The University of Western Australia
Andy is a Professor in the Department of Civil, Environmental and Mining Engineering at The University of Western Australia in Perth. He has a Bachelor and Master degree from the University of the Witwatersrand in South Africa, and a PhD from the Imperial College, University of London. He has worked at the University of Queensland, the University of the 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 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. Andy has been involved in many industry-focused projects with current projects including an evaluation of tailings storage facilities monitoring technologies managed by AMIRA and funded by eight mining companies, Future Tails aimed at training, research and education to improve tailings management funded by BHP and Rio Tinto and evaluating potential static liquefaction of tailings to prevent failures, funded by six mining companies as well as the Australian Research Council. Andy is also currently a member of five international tailings review boards.
|Dr David Reid
The University of Western Australia
David is a tailings engineer with 16 years of consulting and research experience in the design, laboratory testing, and analysis of tailings and tailings storage facilities. He is primarily involved in laboratory and in situ characterisation of tailings with respect to their strength, consolidation behaviour, and liquefaction susceptibility. David completed a PhD at UWA on the behaviour of polymer-treated tailings. He has worked at UWA since 2017 as a research fellow on the ARC Linkage project TAILLIQ and more recently on the Future Tails project.
