  1. 1. Rock Evaluation Using Digital Images and Drill Monitoring Data : Before and after rock blasting

    Författare :Sohail Manzoor; Anna Gustafson; Håkan Schunnesson; Daniel Johansson; Philipp Hartlieb; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Measurement while drilling; Photogrammetry; Rock fragmentation; Gruv- och berganläggningsteknik; Mining and Rock Engineering;

    Sammanfattning : This research is carried out to better understand the nature of the rock mass and to have a better anticipation of rock fragmentation before blasting the rock mass. Current practices of assessing rock mass usually involve techniques that focus on the surface or outcrop of the rock mass such as scanline surveys, window surveys, photogrammetry and laser scanning etc. LÄS MER

These challenges are mirrored in the perceptions of the Liberian population, who see returnees as less legitimate in government positions than stayees. LÄS MER

  5. 5. On the Nature of Cemented Carbide Wear in Rock Drilling

    Författare :Ulrik Beste; Staffan Jacobson; Mikael Olsson; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; cemented carbide; wear; rock drilling; rock; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : WC/Co cemented carbide is a composite material for highly demanding wear applications. The unique combination of hardness (from the WC-phase) and toughness (from the binder Co) gives a material especially suitable for rock drilling. LÄS MER
