1. 1. Rockfalls from rock cuts beside Swedish railroads : A full scale fieldtest, to investigate rockfalls and how rock bounces

   University essay from KTH/Jord- och bergmekanik

   Author : Thomas Thorbjörnson Lind; [2016]
   Keywords : Rock cuts; rockfall; field test; coefficient of restitution; railway; Sweden; risk; Bergsskärning; stenras; fältförsök; coefficient of restitution; järnväg; Sverige; risk;

   Abstract : Rockfalls is a major problem around the world, if they occur in populated areas, they can cause major damage to infrastructure, injure or kill people. For this reason, it is important to be able to predict where the risk of rockfalls and how to prevent and protect populated areas from them. However, it is no easy task to predict rockfalls.

3. 2. Significance of Fracture Patterns in a Rock Mass during Excavation by Blasting in Bandhagen, Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Mattias Ryttberg; [2015]
   Keywords : Fracture sets; rock excavation; rock wall; instability; Spricksystem; utschaktning; bergvägg; instabilitet;

   Abstract : When excavating a rock wall by blasting, pre-existing structures in the rock has a strong impact on the stability of the wall. For excavation in Bandhagen in Stockholm, the nature and orientation of the pre-existing geological features, namely fractures, were not taken into consideration before excavation begun. READ MORE

4. 3. Re-processing of reflection seismic data from line V2 of the HIRE Seismic Reflection Survey in the Suurikuusikko mining and exploration area, northern Finland

5. 4. Proterozoic hydrothermal alteration and mineralization along the Protogine Zone in southern Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Daniel Larsson; [1996]
   Keywords : geography; geology; Proterozoic hydrothermal alteration; mineralization; Protogine Zone; Sweden; Earth and Environmental Sciences;

   Abstract : Occurrences of high alumina rocks constituted by quartz, kyanite, rutile and Al-phosphates are spatially related with the Protogine Zone, a system of ductile and brittle deformation zones within the Proterozoic crust of southern Scandinavia. A hydrothermal origin has been proposed for high alumina rocks at Västanå, based on the chemistry of these rocks, while gradual transitions between magmatic rocks and high alumina rocks at Hökensås and Hålsjöberg suggest a similar origin.

6. 5. Evaluation of methods for rock mass characterization and design of rock slopes in crystalline rock

   University essay from KTH/Jord- och bergmekanik

   Author : Johanna Gottlander; []
   Keywords : Geology; rock mechanics; rock slope stability in fractured crystalline rock; rock mass characterization and classification; rock slope design; slope failure;

   Abstract : Construction of rock slopes is needed in many civil work projects. It is for example very common in road and railway cuts, but other applications include excavation for tunneling or building foundations, where perhaps sensitive constructions are present in the immediate vicinity.
