  1. 11. Green liquor dregs-amended till to cover sulfidic mine waste

    Författare :Susanne Nigéus; Christian Maurice; Thomas Pabst; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Applied Geochemistry; Tillämpad geokemi;

    Sammanfattning : The mining industry produces massive amounts of waste that without treatment and in contact with oxygen can result in acid rock drainage (ARD) and increased leaching of metals. In Sweden, the common way to manage the mine waste after closure is to apply a dry coverage on top of the waste deposition. LÄS MER

  3. 12. Tailings Dam Performance : Modeling and Safety Analysis of a Tailings dam

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

    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

  4. 13. Coarse dust particle transport model around Malmberget mining area

    Författare :Yi Huang; John McManus; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The dust generated from mining activities in the mining area is an important environmental issue for modern mining industries with many environmental problems involved. Number of researcher worked on small dust particle transport, but few work related to the coarser dust particles with 10 to 100 micro meters diameters had been made despite the fact that coarser dust transport have significant influence on the human lives (e.

  5. 14. The Principle of Scaling of Geographic Space and its Application in Urban Studies

    Författare :Xintao Liu; Bin Jiang; Yifang Ban; Meng Liqiu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographic space; scaling; GIScience; VGI; OSM; heavy-tailed distribution; the head tail division rule; space syntax; nature street; urban sprawl; floating car data; hierarchical spatial structure;

    Sammanfattning : Geographic space is the large-scale and continuous space that encircles the earth and in which human activities occur. The study of geographic space has drawn attention in many different fields and has been applied in a variety of studies, including those on cognition, urban planning and navigation systems. LÄS MER

  7. 15. Effect of Physical Weathering on Mechanical Properties of Tailings

    Författare :Juan Rodriguez; Kauko Kujala; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : The mining activity produces minerals to supply to the modern society with commodities. During the ore refining process large amounts of tailings are generated as waste. Tailings are the result of crushing and wet milling, typically in the size range of sand to silt and angular in shape. LÄS MER
