Preventing mining disasters: reducing the risk of tailings dam failure

该项目旨在提高尾矿储存设施(TSF)的安全性。选矿会产生称为尾矿的废物，尾矿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组分筑成的堤坝所包含的场地上。TSFs的部分区域是部分饱和的，具有高浓度的细颗粒，并且物理上随着年龄的变化而变化。它们对地震荷载和液化的抵抗力，以及由这些特性引起的震后强度，人们知之甚少，也无法可靠地量化，因此将在这里讨论。预期成果将更新TSFs设计和管理的行业指南。矿山将受益，失败将被防止。

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.
