Tailings dam rehabilitation is a complex task requiring both technical expertise and innovative solutions. These large structures, holding millions of cubic metres of mining waste, present significant environmental and societal risks if not managed properly. Here, Senior Geotechnical Engineer, Ahmad Zarei delves into the evolving methods used to safely rehabilitate tailings dams, exploring cutting-edge approaches that balance environmental responsibility with long-term structural stability.

Tailings dams were once almost an afterthought in the design and management of mines. But a series of high-profile tailings dam failures and the resultant scrutiny from media, investors and insurers has led to significant changes in how the dams are designed, operated, monitored and managed over their entire lifecycle.

Friction sat down with world-leading tailings dam expert, Professor David Williams from The University of Queensland to find out how things are changing for the better.
