2. 1. Bonded Particle Model for Jointed Rock Mass

   Author : Diego Mas Ivars; Joanne MR Fernlund; John Harrison; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bonded particle model; Smooth-joint contact model; Discrete fracture network; Synthetic rock mass; Jointed rock mass; Geoengineering; Geoteknik;

   Abstract : Jointed rock masses are formed of intact rock and joints. There-fore, proper characterization of rock mass behavior has to consid-er the combined behavior of the intact rock blocks and that of the joints. This thesis presents the theoretical background of the Synthetic Rock Mass (SRM) modeling technique along with example applica-tions. READ MORE

4. 2. Heterogeneous Bonded Particle Modelling of Rock Fracture

   Author : Albin Wessling; Jörgen Kajberg; Simon Larsson; Pär Jonsén; Timo Saksala; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock; DEM; BPM; fracture; drilling; dynamic; Solid Mechanics; Hållfasthetslära;

   Abstract : The dynamic fracture process of rock materials is of importance for several industries, such as the rock drilling process in geothermal and mining applications. Gaining knowledge and understanding of dynamic rock fracture through numerical simulations can enhance the rock drilling process, for example by optimising the drill bit geometry and drilling parameters.

5. 3. Studies on the cement-bonded briquettes of iron and steel plant by-products as burden material for blast furnaces

   Author : Maneesh Singh; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Abstract : During the various stages of iron and steel production a number of iron bearing by-products are generated. These by-products can be made into cement- bonded agglomerates for use as burden material for blast furnaces. READ MORE

6. 4. DEM Modelling and Simulation of Cone Crushers and High Pressure Grinding Rolls

   Author : Johannes Quist; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete Element Method; Modelling; HPGR; Comminution; DEM; Simulation; Crushing; Minerals Processing; Cone Crusher;

   Abstract : The comminution of rock and ore materials consumes ~1.5-1.8 % of the total energy production in mining intensive countries (Tromans, 2008). Several research findings show that there are ways of utilizing compressive breakage modes that are more energy efficient compared to conventional grinding circuits based on large inefficient tumbling mills.

7. 5. Towards Discrete Element Modelling of Rock Drilling

   Author : Albin Wessling; Simon Larsson; Pär Jonsén; Jörgen Kajberg; Bengt Wikman; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DEM Rock Dynamic Drilling; Hållfasthetslära; Solid Mechanics;

   Abstract : The method of percussive rotary drilling is recognized as the most efficient method for hard rock drilling. Despite the clear advantages over conventional rotary meth-ods, there are still uncertainties associated with percussive rotary drilling. READ MORE
