  1. 1. Safety Evaluation of the Zhaoli Tailings Dam : A seepage, deformation and stability analysis with GeoStudio

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Malin Ljungblad; Johan Bäckström; [2016]
    Nyckelord :;

    Sammanfattning :  The mining industry produce large amount of mine waste, also called tailings, which must be kept in tailings dams. In this thesis the safety and stability of a tailings dam have been studied, where some of the tailing material is being used as filling material. The dam has been modelled and simulated using the software Geostudio. LÄS MER
