    Abstract : Prior to an underground excavation a site investigation is carried out. This includes reviewing and analysing existing data, field data collected through outcrop mapping, drill core logging and geophysical investigations. READ MORE

  4. 2. Rock damage caused by underground excavation and meteorite impacts

    Author : Ann Bäckström; Robert Zimmerman; John A Hudson; Flavio Lanaro; Pekka Särkkä; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Excavation Damage Zone EDZ ; Fracture analysis; Pre-existing fractures; Class II behaviour; 3D laser scanning; Impact fracturing; Geoengineering; Geoteknik;

    Abstract : The intent of this thesis is to contribute to the understanding of the origin of fractures in rock. The man-made fracturing from engineering activities in crystalline rock as well as the fracturing induced by the natural process of meteorite impacts is studied by means of various characterization methods.

  5. 3. Damaged rock zone around excavation boundaries and its interaction with shotcrete

    Author : David Saiang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gruv- och Berganläggningsteknik; Mining and Rock Engineering;

    Abstract : When an excavation is carried out in a body of rock, the mechanical, hydraulic and physical properties of the rock surrounding the excavation will be disturbed. The zone in which these occur is called the Excavation Disturbed Zone (EDZ) and must be represented in the quantitative assessment of the near-field host rock. READ MORE
