Wouter Hartman presents at the 9th International Symposium on Rockbursts and Seismicity in Mines – Santiago, Chile Nov 2017



Wouter Hartman presents at Eastern Australia Ground Control Group – Sydney May 2017

This presentation describes the hazards and risks associated with shotcrete or applied sprayed concrete as part of a ground support system. A number of incidents have been associated with shotcrete as part of the ground support system being subjected to strong ground motion. The presentation highlights certain deficiencies (e.g. design approach) in assessing the capability and performance of shotcrete as an appropriate containment system in pseudo-static to dynamic ground conditions. The presentation highlights the urgency for all ground support systems to be re-evaluated which are expected to perform and endure the effects of violent ground motion. The ground engineering principals will emphasize the important underlying factors when a ground support system is designed or selected. In this presentation I’ve urged that assessing the energy capacity of ground support systems is an important process in determining whether a specific surface support and reinforcement system is able to withstand the total energy that the rock mass could exert for a specified location, deformation, velocity, acceleration and displacement. Thus the presentation addresses the hidden dangers of applied sprayed concrete as part of a ground support system subjected to strong ground motion.
