  2. 6. Internal erosion in embankment dams : fluid flow through and deformation of porous media

    Author : J. Gunnar I. Hellström; Thanasis D. Papathanasiou; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : A basic understanding of fluid flow through a porous media facilitates a comprehensive understanding of internal erosion in embankment dams. Hence, it is necessary to reveal the detailed seepage flow, the flow-induced forces acting within the porous media and the fluid flow deformation of the porous media. READ MORE

  4. 7. Predicting surfacing internal erosion in moraine core dams

    Author : Hans Rönnqvist; Anders Wörman; Hans Bergh; Kaare Høeg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; internal erosion; internal stability; filters; moraine core; embankment dams; sinkholes; internal erosion assessment; Geoengineering and mining engineering; Geoteknik och gruvteknik;

    Abstract : Dams that comprise broadly and widely graded glacial materials, such as moraines, have been found to be susceptible to internal erosion, perhaps more than dams of other soil types. Internal erosion washes out fine-grained particles from the filling material; the erosion occurs within the material itself or at an interface to another dam zone, depending on the mode of initiation.

  5. 8. Critical hydraulic gradients in tailings dams : comparison to natural analogies

    Author : Isabel Jantzer; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : The increasing demand of metals and minerals has made it economical for the mining industry to mine low-grade deposits, which results in immense quantities of by-products. In fact, such by-products, i.e. tailings, are the largest waste volumes produced on earth. READ MORE

  6. 9. Monitoring of tailings dams with geophysical methods

    Author : Ganesh Mainali; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : Several dam failure accidents have occurred during the last years and mine tailings dam failures are occurring at relatively high rates. Studies of past earth dam failures show embankment dam problems and failures are often related to internal erosion in one way or another. READ MORE
