1. 6. Determination of dry density in tailings with a Dynamic Cone Penetrometer :

   Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Patrik Hagström; [2017]
   Nyckelord :dynamic cone penetrometer; tailings dam; tailings beach; tailings;

   Sammanfattning : Today mines produce metals which are used for everyday products by people worldwide. When metals are produced, waste products known as tailings are generated. These tailings are commonly stored in impoundments, surrounded by embankment dams. The demands from the society are constantly increasing regarding the quality and safety of dams. LÄS MER

3. 7. Closure of Lilla Bredsjön Tailings Dam : an Evaluation of the Long-Term Dam Safety Measures

   Master-uppsats, KTH/Vattendragsteknik

   Författare :Jenny Bramsäter; [2017]
   Nyckelord :tailings dams; seepage; pore pressure; slope stability; slip surfaces; long-term stability;

   Sammanfattning : The mining industry contributes to enormous amounts of waste all over the world, which places high demands on tailings dams. In Sweden, there are strict regulations regarding the management and treatment of tailings dams, but some dams that were built before these regulations existed still pose a threat to the environment.

4. 8. Stability analysis on a planned Mexican tailings dam

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för teknikvetenskaper

   Författare :Sofie Törnqvist; Amanda Lindquist; [2016]
   Nyckelord :;

   Sammanfattning : If mine waste materials are stored in dams, the dams are referred to as tailings dams. Tailings dam failures can lead to massive destruction in nearby areas because of the large amount of water and slurry tailings stored in the dams. Tailings dams are large constructions which therefore endure great stresses. LÄS MER

5. 9. 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

7. 10. Seepage, Solute transport and Strain-stress Analysis of Ashele Tailings Dams

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Marcus Holmqvist; Marcus Gunnteg; [2014]
   Nyckelord :Tailings dams; seepage; gruvdammar; genomströmning;

   Sammanfattning : This master thesis has been conducted through cooperation between Elforsk, Uppsala University and Tsinghua University in Beijing. Ashele Tailings Dam, located in Haba Town, Xianjing Province, China, is designed and used for high sulphur tailings. LÄS MER
