    Sammanfattning : Drainage of peatlands increases the transport of suspended solids (SS) and the leaching of nutrients to downstream receiving waters. Increased settling of peat and eutrophication of lakes has been noted in many studies downstream from peat mines. LÄS MER

  3. 3. Wetlands as a means to reduce the environmental impact of mine drainage waters

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Åsa Sjöblom; Linköpings universitet.; Linköpings universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lakvatten; våtmarker; vattenrening; miljö; INTERDISCIPLINARY RESEARCH AREAS Water in nature and society; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN Vatten i natur och samhälle;

    Sammanfattning : In many mining regions of the world, pollution of surface water and groundwater by drainage water originating from mines aiming waste poses either a serious threat to the environment, or a severe environmental problem. During the last two and a half decades, treatment of mine drainage water in constructed and natural wetlands has emerged as an alternative to more conventional methods to handle the problem. LÄS MER

    Sammanfattning : Mining has been and still is an important industry in Sweden, it has strongly contributed to the standard of living we have today. Extraction of ore began in the 12th century, but did not come about frequently until the 16th century, which is often seen as the starting age for ore processing and metal extraction. LÄS MER

  5. 5. Reclamation of acid-generating waste rock by in-pit backfilling and sealing An evaluation of the Kimheden mine site, northern Sweden

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Lucile Villain; Luleå tekniska universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : The notion of mine site reclamation is very recent compared to the history of mining. In thepast, mine sites were left as is following termination of the operations, but modern regulationsrequire anticipation of long-term contamination of the surrounding environment and return ofthe land to a sustainable use.
