1. Mechanical Behavior of Tailings : Laboratory Tests from a Swedish Tailings Dam
Sammanfattning : 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. LÄS MER
2. Stability of tailings dams : focus on water cover closure
Sammanfattning : Mining activities have been ongoing for thousands of years within Sweden. As the results of previous activities are evident today, i.e. for example acid mine drainage (AMD), the focus and interest on closure and remediation of mine sites and tailings storage facilities (TSFs) has increased.

3. Stability of tailings dams : focus on numerical modelling
Sammanfattning : 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. LÄS MER
4. Tailings Dam Performance : Modeling and Safety Analysis of a Tailings dam
Sammanfattning : 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. LÄS MER
5. Mechanical Properties of Tailings : Basic Description of a Tailings Material from Sweden
Sammanfattning : 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. LÄS MER
