their lowest payable grade has characterized mining in most parts of the world for several decades. This is due to pressure to meet the expanding demand for mineral commodities in the world market. Mining operations in major mining countries such as South Africa, Canada, and Australia have already gone beyond 4 km, 3 km, and 2 km, respectively (Potvin and Wesseloo, 2013), and this poses serious threats from a safety point of view. Among many identifiable and quantifiable safety hazards associated with deep-level mining, the effect of rockbursts, often manifested by violent ejection of rock from excavation walls, has been a major safety hazard and will continue to pose a threat in future mining, endangering both mine personnel and the structural integrity of the mine (Ortlepp, 1997). Figures 1 and 2 illustrate examples of rockburst damage and support failure under dynamic (rockburst) loading conditions. The rockburst phenomenon is now considered to be a universal problem (Ortlepp, 1997). Numerous cases of rockbursting in civil engineering tunnels developed at great depth have also become prevalent around the world due to the increase in in situ stress fields at such depths. It has been documented that some countries, for example Australia, experience high horizontal stresses that in themselves could result in rockburst damage without necessarily factoring in the effect of depth increase (Ortlepp, 1997; Stacey and Rojas, 2013; Potvin and Wesseloo, 2013). Despite significant research in this area, it cannot be claimed that the rockburst problem is now well understood, nor that a solution has been attained. In fact, many have regarded rockbursts as one of the least understood phenomena. For example, designing a rockburst-resistant support system appears to be far-fetched, considering the complexities associated with quantifying the capacities of A step towards combating rockburst damage by using sacrificial support
