1. Adapted data collection in field utilizing RMR and the Q-system
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : The focus on slope stability has increased rapidly in Norway over the last years due to several unwanted landslides. In Norway, the most used method today to classify the rock mass and to determine the required reinforcement, is the Q-system. In addition to that the RMR method is also a commonly used method.

2. Rock Wedge Stability Assessment : A Comparative Analysis of Limit Equilibrium and Discrete Element Methods
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Rock wedge stability is a common concern in underground excavations. Since the wedge stability influences the support design, it is important to use a wedge stability analysis method that can capture factors like excavation geometry, joint parameters and properties, rock mass properties, rock cover, and stress field as accurately as possible.

3. Character and Evolution of Ore Mineralisation in the Te-Rich Enåsen Au-Cu Deposit, Central Sweden
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The Enåsen gold deposit is located in Gävleborg county in central Sweden. Mining operations at Enåsen took place from 1984 to 1991 with Au as the main target for exploitation. The deposit has been interpreted as a metamorphosed Palaeoproterozoic analogue to near-recent epithermal Au mineralisations of a high sulphidation type. READ MORE

4. Development of a DEM-FEM framework for infrastructure simulations
University essay from Göteborgs universitet / Institutionen för fysikAbstract : This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with elastic bodies. READ MORE

5. Analysis of rock grouting with variable injection pressure
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Rock grouting is an effective technique frequently used in rock engineering to reduce groundwater ingress and increase the stability of surrounding rock mass. The real time grouting control (RTGC) is one of widely used analytical models to predict the grouting process. READ MORE
