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

    Författare :Lucile Villain; Bernhard Dold; Luleå tekniska universitet; []
    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.

  3. 7. Effectiveness of reclamation by backfilling and sealing at Kimheden open-pit mine, northern Sweden

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

    Sammanfattning : Reclamation of mine sites is a very recent concept on the scale of mining history. It involves the prevention or mitigation of the environmental impacts from mining, and the establishment of sustainable post-mining uses of the land. LÄS MER

  4. 8. Gårdar och folk i norr : Bebyggelse, befolkning och jordbruk i Norrbotten under 1500-talet

    Sammanfattning : The aim of this study is to investigate colonization processes and population and agricultural development during the 16th century. The studied geographical area consists of the northern part of the northernmost province of Sweden of that time, Västerbotten. LÄS MER

  5. 9. Seed dynamics and the ecological restoration of hill slopes of Kondoa Irangi, Central Tanzania

    Författare :Herbert V. M. Lyaruu; Ingvar Backéus; Jerry Skoglund; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; anemochorous; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Ecological Botany; Ekologisk botanik;

    Sammanfattning : Improper agricultural practices such as bill slope cultivation, extensive clearing of vegetation using fire over a long period, and to some extent overgrazing have converted the once fertile hill slopes of Kondoa Irangi in central Tanzania into unproductive marginal land. It is 25 years now since reclamation measures were introduced to save the hills from further degradation, but the regeneration process, has been rather slow. LÄS MER

  7. 10. Mechanical properties of stabilized dredged sediments : for sustainable geotechnical structures

    Författare :Gregory Paul Makusa; Göran Holm; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Dredging activities at Ports and Harbors are inevitable for the safe navigation of ships and vessels. Dredged material may range from very fine and contaminated sediments to sand and gravels. While, granular dredged material can be directly utilized in civil engineering applications, fine sediments may require further treatment before use. LÄS MER
