  1. 1. Identification and strength classification of weakness zones in the Garpenberg mine based on measurement while drilling (MWD)

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Ioannis Peroulakis; [2022]
    Keywords : Drilling; MWD; Garpenberg; Mining; Geotechnics;

    Abstract : Boliden’s Garpenberg mine produces Zn-Pb-Ag(Cu-Au) using a sublevel stoping with pastefill mining method. The orebody is strongly affected by the existence of weakness zones mainly consisting of Talc Schist and Phlogopite Schist which affect the design, planning and production of the stope. READ MORE

  6. 5. The influence of weakness zones on the tunnel stability based on investigations in Bodøtunnelen

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Viktor Renström; [2016]
    Keywords : Rock mechanics; Numerical modeling;

    Abstract : When planning for a tunnel, the ground conditions in which the tunnel is going to be excavated through will be investigated to different extent. Lack of relevant pre-investigation data or misinterpretations of the available data can cause both economical and/or unexpected stability problems. READ MORE
