  2. 1. Impact wave process modeling and optimization in high energy rate explosive welding

    Author : Mohammad Tabatabaee Ghomi; Jafar Mahmoudi; Nils Erik Hannerz; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Explosive welding; Impact; Wave; Deformation; Velocity; Engineering mechanics; Teknisk mekanik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Impact waves are used in many different industries and are classified according to whether they cause plastic or elastic deformations. In the plastic deformation mode, these waves can be used to produce special electrical joints. In the elastic deformation mode, they can be used to detect leakage or to measure the thickness of pipes. READ MORE

  4. 2. Development of a methodology for in-situ dynamic testing of ground support

    Author : Shahin Shirzadegan; Lars-Olof Dalhström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : The increasing mining depth leads to higher stress magnitudes, resulting in increased seismic activity and more seismically-induced damage. The effectiveness of the ground support system under dynamic loading conditions has therefore become of prime interest to the mining companies in order to provide safe mining conditions with a minimum of production disturbances caused by unstable infrastructure.

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

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

    Abstract : 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. READ MORE
