In this Research, a ground reinforcement design method introduced that facilitates the selection of a suitable reinforcement system using the estimation of ground energy demand and measurement of rockbolts energy dissipation capacities and guides the designer to adjust it based on observed ground and support reaction. Rock bolt dynamic tests under single and multiple impacts simulating seismic mining conditions improved the knowledge of bolt behaviour under those conditions.

Influence of uncertain source parameters on strong ground motion simulation with the empirical green's function methodLiang, J.; Hao, Hong (2009)A combined stochastic and Green's function approach was developed to simulate strong ground motions in Southwest Western Australia (SWWA) in a previous study. Although it was demonstrated that adopting the source parameters ...
