Dynamic loading of rock bolts is a complex topic that requires a thorough understanding of rock mechanics, bolt type and materials, static and dynamic loading processes. This report addresses this problem by using a combination of data collection in a controlled environment, the Kiirunavaara Mine, and numerical modelling of complex, multi-opening excavations in order develop a method for comparing and improving design of support systems.
