    University dissertation from Department of Water Resources Engineering, Lund Institute of Technology, Lund University

    Author : Bjørn Kløve; Lunds universitet.; Lund University.; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; drainage artificial floodplaines; phosphorus; suspended solids; nitrogen; erosion; peat mining; peak runoff controll; sedimentation; water treatment; water resources; hydrology; hydraulics; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : 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. READ MORE

  2. 2. Effects of confinement and initiation delay on fragmentation and waste rock compaction Results from small scale tests

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Daniel Johansson; Luleå tekniska universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gruv- och Berganläggningsteknik; Mining and Rock Engineering;

    Abstract : Sub-level caving (SLC) is classified as a mass mining method and there is an increasing interest in its application worldwide and in a very wide range of geotechnical environments. Design of sub-level blasting rounds and optimization has become more important now when the sizes of the blasting rings have become larger. READ MORE

  3. 3. Automation of Load Haul Dump machines comparative performance analysis and maintenance modeling

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Anna Gustafson; Luleå tekniska universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : The Load Haul Dump (LHD) machine and its operating environment create a complex system. Mine productivity depends on the operation of the LHDs and on the mining environment, including fragmentation, size of boulders, navigation techniques etc. Traditional navigation techniques require a lot of infrastructure to accommodate automatic operation.

    Abstract : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. READ MORE

  5. 5. Decision support models for the maintenance and design of mill liners

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Rajiv Dandotiya; Luleå tekniska universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Mining companies use heavy-duty equipment that work round the clock in highly abrasive environments. Autogenous (AG) mills used in the mining industry and in ore dressing plants are examples of major bottlenecks in the context of downtime and exert an influence on production economics. READ MORE
