1. Towards Discrete Element Modelling of Rock Drilling
Sammanfattning : 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. LÄS MER
2. Novel methods for 3-D semi-automatic mapping of fracture geometry at exposed rock faces
Sammanfattning : To analyse the influence of fractures on hydraulic andmechanical behaviour of fractured rock masses, it is essentialto characterise fracture geometry at exposed rock faces. Thisthesis describes three semi-automatic methods for measuring andquantifying geometrical parameters of fractures, and aims tooffer a novel approach to the traditional mapping methods. LÄS MER
3. Lined underground openings : rock mechanical effects of high internal pressure
Sammanfattning : .... LÄS MER
4. Efficiency of a percussive process for fragmentation of rock and similar materials
Sammanfattning : .... LÄS MER
5. Heterogeneous Bonded Particle Modelling of Rock Fracture
Sammanfattning : 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.
