Rock support and reinforcement are two distinct techniques used for control of rock behaviour around underground excavations in mines. Support is used to provide areal restraint at the excavation surface while reinforcement is used to improve the overall stability of the rock mass adjacent to the excavation. The requirements for support and reinforcement vary widely. These Symposium Proceedings bring together recent developments in both techniques of ground control and up-to-date experiences in their use at operating mines throughout many countries.
