ABSTRACT
Rockfalls remains one of the major sources of injuries and fatalities in underground metal mines (Potvin et al. 2003). A number of control measures can be applied to mitigate the risk associated with rockfalls. For example, exclusion zones, remote equipment and specific working procedures can assist in removing personnel from being exposed to rockfall hazards. Another widely used approach involves ground support and reinforcement, which mitigates rockfall risks by reducing the likelihood of rockfalls. In most mines, this is the control measure of choice. In fact, many countries have adopted regulations encouraging the use of some form of ground reinforcement in all mine excavations accessed by mine workers.
