  2. 1. Tailings Dam Performance : Modeling and Safety Analysis of a Tailings dam

    Author : Roger Knutsson; Annika Bjelkevik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Storage and management of mine waste are both needed in the mining industry. After mineral extraction of the ore, there are generally leftovers with insufficient economical value that need to be taken care of. The finest grained fractions are referred to as tailings. READ MORE

  4. 2. Mechanical Behavior of Tailings : Laboratory Tests from a Swedish Tailings Dam

    Author : Riaz Bhanbhro; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailings dams; Tailings; Mechanical Behavior; Oedometer; Direct Shear; Triaxial; Shear strength; Soil Mechanics; Geoteknik;

    Abstract : Tailings is leftover material from mining industry and is produced in huge quantities approximately 70-99% of the ore production.  Tailings material is stored as impoundments by constructing tailings dams which are often constructed with tailings material itself. READ MORE

  5. 3. Mechanical Properties of Tailings : Basic Description of a Tailings Material from Sweden

    Author : Riaz Bhanbhro; Peter Viklander; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Tailings dams are constructed to store waste material from mining industry and usually these dams are raised with time depending upon production rate. Tailings material is sometimes used in construction of tailings dams. READ MORE

  6. 4. Numerical analyses of stability of a gradually raised tailings dam

    Author : Muhammad Auchar Zardari; Daichao Sheng; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tailings dams; consolidation; rockfill berms; slope stability; corner; internal erosion; finite element analysis; Soil Mechanics; Geoteknik;

    Abstract : Numerical analyses are presented in this thesis to address potential stability problems that may occur during gradual raisings and under seismic loading conditions of Aitik tailings dam in northern Sweden. The dam is mainly raised using upstream construction method. It is planned to raise the dam gradually in several stages. READ MORE

  7. 5. Stability of tailings dams : focus on numerical modelling

    Author : Muhammad Auchar Zardari; Anders Sellgren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Upstream tailings dams may experience slope stability problems when the rate of raising is too fast. Tailings consolidate slowly due to low hydraulic conductivity. The excess pore pressures can build up due to accelerated rate of raising. READ MORE
