21. Geophysical 3D models of Paleoproterozoic Iron Oxide Apatite mineralization’s and Related Mineral Systems in Norrbotten, Sweden
Abstract : The Northern Norrbotten ore district hosts a multitude of Sweden’s mineral deposits including world class deposits such as the Malmberget and Kirunavaara Iron oxide apatite deposits, the Aitik Iron oxide copper gold deposit, and a multitude of smaller deposits. Northern Norrbotten has been shaped by tectonothermal events related to the evolution of the Fennoscandian Shield and is a geologically complex environment. READ MORE

22. Fault detection and model quality estimation using mixed integer linear programming
Abstract : Robustness is a necessary property of a control system in an industrial environment, due to changes of the process such as changes of material quality, aging of equipment, replacing of instrument, manual operation (e.g. a valve that is opened or closed) etc. READ MORE

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

24. Predominant failure mechanisms at the Kiirunavaara mine footwall
Abstract : The Luossavaara-Kiirunavaara Aktiebolag (LKAB) Kiirunavaara mine is a large scale sub-level caving (SLC) mine in northern Sweden. The use of SLC as a mining method inherently causes significant rock mass movements above the extraction level. READ MORE

25. A dispatch procedure for traffic control of a fleet of remote-controlled automatic LHDS in underground hard rock mines : modelling approach is based on simulation
Abstract : A concept for automating Load-Haul-Dump (LHD) vehicles has stimulated considerable interest in the Swedish mining industry. In this concept, tramming and dumping operations of an LHD should be automatic. During loading, an operator from a control room fills the bucket of a vehicle via remote-control aided by a television system. READ MORE
