Considering Liquefaction of Tailings Workshop – 12th Nov 2019 at the University Club of WA

Why?  Recent Tailings Dam failures have stunned the industry and highlighted the risks associated with the liquefaction of tailings.

Find out what liquefaction is, how we can detect if we have a problem on existing dams, how to design for liquefied conditions in new dams and how to retrofit existing dams. How can we manage risks with potentially liquefiable tailings? Can we get better understanding of static liquefaction triggers?

Meet and network with practitioners, regulators and mining industry personnel with a common interest in tailings dam risk.

Who?  This workshop will help managers, designers and mine operational personnel involved in tailings dam management, understand the background to the issue of liquefaction of tailings that is currently a major concern in our industry.

What to expect?  The workshop will feature technical presentations from leading Australian practitioners in the field of tailings liquefaction, explaining what it is, how to determine the potential for liquefaction , how to design for the possibility of liquefaction occurring and operational controls. Workshop sessions will allow attendees opportunity for discussion of vital issues affecting our industry approach to tailings liquefaction.
