Is an Engineer of Record needed for tailings storage facilities in Australia? We explore the effectiveness and potential issues of including an Engineer of Record for TSFs in Australia.
Covid-19 has demonstrated without any doubt that government has the power to re-create our economic landscape, for better or worse. In that light, Rowan Cossins, Principal in our Brisbane office, explains four practical actions that government could adopt from a waste management perspective to benefit Australia’s circular economy.
The ATC Williams NATA accredited soil and tailings laboratory is equipped to carry out complex monotonic and cyclic triaxial testings required for assessment of liquefaction. In this article we define how to establish a critical state line using triaxial shearing tests.
The right capping technique to be deployed for a tailings storage facility will depend upon the in-situ conditions, client requirements for final land use and the desired time frame for rehabilitation. We profile five capping techniques and their best applications.
At a time where Filtered Tailings is trending in mine tailings management, we take a holistic view based on 40 years of experience in conservation and safety. Please read as we explore the benefits of Thickened Tailings including the CAPEX and OPEX advantages of using a Central Thickened Discharge system.
The QLD regulator (DES) recently released a discussion paper on Energy from Waste (EfW) policy, and also held a workshop. So, just for fun, lets dive into the topic at bit, with a Queensland focus.
