  1. 1. Deformation and failure of brittle rocks under compression

    Författare :Chunlin Li; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : This thesis describes the deformation and failure of rocks under compression through a micromechanics model and laboratory studies of the Kaiser effect. It comprises an overview and seven appended papers. The deformation model is developed based on the analysis of the behaviour of microcracks. LÄS MER

  4. 3. Wave propagation in rock and the influence of discontinuities

    Författare :Andreas Eitzenberger; Charlie Chunlin Li; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : This thesis concerns wave propagation in rock as a tool for determination of rockproperties and as a consequence of activities, such as trains.Using waves as a tool often means that rock properties are determined or the interior of a sample is studied without being damaged.

  5. 4. Development of a Methodology for Dynamic Testing of Rock Support : Field Tests and Numerical Analysis

    Författare :Shahin Shirzadegan; Erling Nordlund; Ping Zhang; Charlie Chunlin Li; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : The increasing mining depth in the Luossavaara-Kiirunavaara Aktiebolag (LKAB) mine located in the northern part of Sweden leads to higher stress magnitudes, resulting in increased seismic activity and more seismically-induced damage. The effectiveness of various ground support systems under dynamic loading conditions has therefore become of prime interest to LKAB for successful and safe mining at deep levels. LÄS MER
