This project aims to improve safety of tailings storage facilities (TSFs). Mineral processing produces waste called tailings, being mixtures of water and soil-sized particles. Tailings are stored on sites contained by embankments made from soil or a coarse component of tailings. Sections of the TSFs are partially saturated, have high concentrations of fine particles and physically change with age. Their resistance to earthquake loading and liquefaction, and strength post-earthquake, arising from these properties are poorly understood and can not be quantified reliably so will be addressed here. Anticipated outcomes will be updated industry guidelines for the design and management of TSFs. Mines will benefit and failures will be prevented.

该项目旨在提高尾矿储存设施（TSF）的安全性。选矿过程产生称为尾矿的废物，是水和土壤大小的颗粒的混合物。尾矿储存在由土壤或尾矿的粗成分制成的堤坝所包围的地点。 TSF 的部分部分饱和，具有高浓度的细颗粒，并且随着时间的推移而发生物理变化。由于这些特性而产生的它们对地震荷载和液化的抵抗力以及地震后的强度人们知之甚少，并且无法可靠地量化，因此将在此处讨论。预期成果将是更新 TSF 设计和管理的行业指南。矿山将受益，故障将得到预防。
