Abstract: Ground support is an integral part of geomechanical risk management in deep and high-stress mines. Maintaining the integrity of underground excavations under extreme ground conditions has been the driving force for significant innovations in ground support technology. In addition, access to powerful analytical and numerical tools and monitoring technology have illustrated opportunities for significant improvement in the design process. This paper employs field observations, performance data from controlled laboratory experiments, and forensic investigations to challenge common assumptions in the design and implementation of ground support systems in deep and high stress mines. 

Keywords: ground support, material properties, rockbolt configuration, quasi-static and impact testing, field observations, forensic investigations
