11. Assessment of rock mass quality and its effects on charge ability using drill monitoring technique
Sammanfattning : For an efficient mining operation, it is essential to have as much information as possible aboutthe ore to be excavated and the rock masses surrounding the ore. Geological information andthe content and distribution of extractable minerals, are central concerns for long term mineplanning. LÄS MER
12. Drip Sealing Grouting of Tunnels in Crystalline Rock: Conceptualisation and Technical Strategies
Sammanfattning : A conceptual model of the groundwater hydraulic conditions around the tunnel contour in ancient brittle crystalline rocks has been developed and verified. The general aim has been to reach an understanding of the groundwater conditions in and close to the tunnel roof where dripping takes place and to propose technical and practical strategies for waterproofing.

15. Structural and neural network analyses of fracture systems at the Äspö Hard Rock Laboratory, SE Sweden
Sammanfattning : The > 10,000 fractures documented in the 450m deep Äspö Hard Rock Laboratory (HRL) provide a unique opportunity to study brittle deformation of a Swedish bedrock mass. The fracture population consists of six major sets, one subhorizontal and five sub-vertical. LÄS MER
