ANCOLD 2021 Tailings Dam Operators Forum
The ANCOLD 2021 Tailings Dam Operators Forum was held in Gladstone Queensland in May 2021. It was a platform for tailings dam operators to share experiences (good and bad) rather than a technical/engineering focused conference.
With the enormous focus on Tailings Dam Design and Construction over recent years, the challenges facing the operators of tailings dams is often overlooked. The global tailings industry and stakeholders have acknowledged that a step-change is required to eliminate failures such as the events that occurred in Brazil, Mt Polley (Canada) and Cadia. It is noted that there have been 7 additional tailings dam failures since the Brumadinho failure in Brazil on 25 January 2019.
On 25 June 2020, the Global Industry Standard on Tailings Management was endorsed by all stakeholders involved with the Global Tailings Review. This standard establishes robust requirements for the safer management of both existing and new tailings facilities globally. One session of the forum focuses on the operational aspects of the Global Standard.
Tailings management attracts extremely passionate people, and this forum invited like-minded attendees to participate in an open environment to benefit from others’ successes and learnings. This national forum brought together the ‘front line’ of tailings dams to openly discuss their experiences with the outcome of improving awareness of tailings management systems and operational safety.

Tailings Dams (May 2014) – MODULES 1 to 4 (Full Seminar)
Tailings dams are critical elements in most mine operations throughout Australia but it is evident that many of these dams have not been implemented and sustainably managed in line with modern day “risk management” approaches. This course is being provided to assist tailings dam owners, and their professional staff and advisers to provide up-to-date information on how to plan, implement, operate and sustainably close their dams in a safe and effective manner consistent with various Government and “duty of care” obligations.

Dam Spillways (May 2015) – MODULES 1 TO 4
Full course
COURSE OBJECTIVES AND OUTLINE
This short course is designed so that engineers and other dam professionals both young and more experienced will better understand the essential ingredients of investigation, design, operation, maintenance and safety for spillways and outlets for new and existing dams and associated upgrades.While ensuring the basics are properly understood, there will be a strong focus on what is the approaches, issues and risks associated modern dam spillways & outlets requirements – what you need to know, whether a dam owner/manager/operator, consultant, regulator or a professional with a strong interest in dams.
Dam Spillways will look at spillways which are being called upon to handle larger and larger discharges due to revisions to hydrology data, trends in risk evaluation and other issues. It covers both broad criteria for sound spillways (including ungated, gated & fused spillways) and the specific criteria to enable a proper understanding of how and why spillways work or don’t work or what needs to be improved, how to be confident in their operation, how to maintain them and overall make them safe. It will include descriptions of a range of cases – particularly those which have shown a new understanding and respect for large discharges, risks and overall safety and best practice management of spillways.
