Gordon graduated as a civil engineer at the University of the Witwatersrand in 1974. Gordon has worked as a consulting engineer to the mining industry specialising in the geotechnical and environmental aspects of mine waste management for 35 years and has participated in projects in Africa, Australia and North and South America.
Dr Angus Paterson – Technical Organising and Editorial Committees
Director, Paterson & Cooke Consulting Engineers (Pty) Ltd, South Africa
Angus is the managing director of the Cape Town office of Paterson & Cooke, having founded the company together with Dr Robert Cooke in 1991.
Angus completed his Civil Engineering degree at the University of Cape Town, South Africa in 1984 and continued post-graduate studies, completing an MSc in 1986 and a PhD in 1991. His research work focused on the flow behaviour of high concentration backfill slurry pipelines.
Angus has been directly involved in analysis and design of slurry transport systems since 1987 and has worked on slurry pipeline projects throughout the world. These include long distance slurry pipelines, underground paste and backfill distribution systems and numerous conventional, thickened and paste tailings disposal systems.
David Reid – Australian Committee
Research Fellow, School of Civil, Environmental and Mining Engineering, The University of Western Australia
David is a tailings engineer with 12 years’ experience in the design, laboratory testing, investigation, and analysis of tailings and tailings storage facilities. David’s focus is on the laboratory and in situ characterisation of tailings with respect to strength, consolidation, and liquefaction. A particular focus of his work in on assessing the in situ state and liquefaction susceptibility of upstream tailings facilities in a critical state framework. David recently submitted his PhD at The University of Western Australia, which involved studying the properties of polymer-treated tailings and the use of centrifuges to perform consolidation testing.
