  1. 6. On the behaviour of tailings dams : Management in cold regions

    Författare :Roger Knutsson; Jan Laue; Andy Fourie; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Associated to mining activities there is mine waste generated. The residues left over from mineralextraction processes are referred to as tailings, normally stored in surface tailings facilities. Thefacilities are usually confined by embankment dams, so called tailings dams. LÄS MER

  3. 7. Grout Development and Methods for Remedial Grouting of Embankment Dams

    Författare :Johan Lagerlund; Jan Laue; Peter Viklander; Markus Aufleger; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : An embankment dam can be damaged by internal erosion. During this process, the soil material erodes and is transported out of the dam structure. Some common types of damage due to internal erosion are piping, less dense soil zones, and zones where the fine material has been washed out. LÄS MER

  5. 9. Recycling of green liquor dregs in cover application on acid generating mine waste

    Författare :Susanne Nigéus; Jan Laue; Christian Maurice; Jenny Lindblom; Helge Hellevang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : The mining industry generates massive amounts of waste that without treatment and in contact with atmospheric oxygen can cause the formation of acid rock drainage (ARD). In Sweden, the most common reclamation measure for mine waste is to apply a multi-layer cover on top of the waste deposit. LÄS MER

  7. 10. Investigation of Suffusion in Glacial Till Dam Cores : Testing methods and critical hydraulic gradients

    Författare :Ingrid Silva; Jan Laue; Peter Viklander; Thomas Pabst; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; internal erosion; suffusion; glacial till; dam cores; dams; experimental investigation; hydraulic gradient; testing methods; cohesionless soils; granular soils; Geoteknik; Soil Mechanics;

    Sammanfattning : Suffusion is an internal erosion mechanism that occurs in embankment dams when fine grained particles in the dam core are washed out by seepage. Initiation of internal erosion depends mainly on three major factors: grain size distribution of the soil, stress conditions and hydraulic gradient; whilst its continuation depends on the properties of the filter.
