Abstract
This conference paper critically examines the concept of ‘credible failure modes’ in the context of tailings storage facility (TSF) risk assessment and management, focusing on its interpretation and practical implications as defined by the Global Industry Standard on Tailings Management (GISTM) and other key guidelines. Emphasising the foundational role of identifying potential failure modes, the paper reviews definitions and applications across various industry standards and discusses common challenges. It proposes a pragmatic approach that focuses on the intent of the process, rather than the unnecessary and distracting separation of ‘credible’ and ‘non-credible’ failure modes. Practical examples are provided to illustrate the recommended approach, aiming to foster industry alignment towards the united goal of improving TSF safety.
