Recent catastrophic failures of tailings storage facilities have highlighted the critical roles that dam engineers can play in ensuring public safety, and have motivated the mine waste industry to assess and improve the practice of tailings dam breach analysis (TDBAs). As industry moves towards a standard of no catastrophic failures, it is critical that practitioners, owners, and operators have a unified understanding when conducting TDBA, in order to provide a high level of confidence within communities and environments surrounding operational or closed facilities. Currently, uncertainties exist surrounding the industry’s standard practice in conducting appropriate TDBA. This paper provides a summary of the currently available approaches and models for TDBA and when it is appropriate to use a particular method. A critical review of key challenges of TDBA (release volume estimate, hydrograph development, and routing the breach hydrograph downstream) is also provided. This paper aims to be a thorough summary of what is known about TDBA and a reference source for engineers and researchers.

尾矿坝破坏分析：方法、实践和不确定性的回顾

最近尾矿库设施的灾难性故障凸显了大坝工程师在确保公共安全方面可以发挥的关键作用，并促使矿山废物行业评估和改进尾矿坝溃口分析 (TDBA) 的做法。随着行业朝着无灾难性故障的标准迈进，从业者、业主和运营商在进行 TDBA 时必须有统一的理解，以便在运营或封闭设施周围的社区和环境中提供高度的信心。目前，围绕行业在进行适当的 TDBA 的标准做法方面存在不确定性。本文总结了当前可用的 TDBA 方法和模型以及何时适合使用特定方法。还提供了对 TDBA 关键挑战的批判性审查（释放量估计、水道线开发和下游突破水道线）。本文旨在全面总结有关 TDBA 的知识，并为工程师和研究人员提供参考资料。
