Abstract
In the rapidly evolving field of tailings storage facility (TSF) closure planning, understanding and addressing long-term uncertainties is pivotal for creating sustainable and resilient designs. This presentation delves into the complex interplay between engineering practice and the inherent uncertainties affecting TSF closure.
Central to this discussion is the impact of climate change, which introduces significant variability in weather patterns and extreme events that must be anticipated in closure design. By integrating advanced modelling tools, such as rain-on-grid and landform evolution models, we aim to address challenges specific to TSF stability and seepage over time.
The session will explore the influence of evolving legislation and best practice guidelines, such as the Global Industry Standard on Tailings Management (GISTM), which encourages rigorous design criteria including storm and seismic event resilience.
Complementing this is the growing expectation from stakeholders, including local communities and regulatory bodies, for more transparent and inclusive planning processes. Engaging in effective stakeholder consultation becomes essential for achieving consensus and ensuring socioeconomic and ecological viability post-closure.
We will discuss practical approaches to addressing these uncertainties, emphasising adaptive management strategies and the application of progressive reclamation techniques. The goal is to ensure that closure designs not only comply with legislative requirements but also anticipate and accommodate the perspectives of diverse stakeholders, thereby harmonising industrial aims with societal and environmental expectations.
