    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : Rock Mass behavior and Cap Rock Stability at the Malmberget MineThe LKAB Malmberget mine is mined using sublevel caving. This mining method requires continuous caving of the hangingwall, which also result in ground deformations on the surface. LÄS MER

  2. 2. Caving mechanisms for a non-daylighting orebody
