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

    Författare :Ann Bäckström; Robert Zimmerman; John A Hudson; Flavio Lanaro; Pekka Särkkä; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. 4. Mine-scale rock mass behaviour at the Kiirunavaara Mine

    Författare :Jessica Vatcher; Flavio Lanaro; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : The interaction of the geological and mining environments leads to a variety of forms of rock mass behaviour, including seismicity and falls of ground. A precise understanding, however, of the role of geology in rock mass behaviour experienced by Luossavaara-Kiirunavaara Aktiebolag’s (LKAB) Kiirunavaara Mine remains unknown. LÄS MER
