Preventing mining disasters: reducing the risk of tailings dam failure

本项目旨在提高尾矿库的安全性。矿物加工产生的废料被称为尾矿，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制成的堤防所包含的场地上。TSFs的剖面部分饱和，具有高浓度的细颗粒，并且随着年龄的增长而发生物理变化。它们对地震载荷和液化的抵抗能力以及震后强度，由于这些特性而产生的理解很少，无法可靠地量化，因此将在这里讨论。预期的结果将是更新设计和管理tsf的行业指南。地雷将受益，并将防止失败。

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.
