Title

Support of Underground Excavations in Deep-Level, Hard-Rock Mines - 2. Tunnels and Other Non-Tabular Excavations

Abstract

Part 2 of this article reviews the support methods normally used to protect square-shaped tunnels and other non-tabular excavations in South Africa gold mines. This is followed by a discussion of the effects of these support methods and shaping of tunnel stability under stressed conditions. By using the theory of elasticity and observations of the physical conditions in tunnels located in deep hard-rock mines where various support systems are used, it has been possible to define the stress limits to which the support methods are effective. This study highlights the potential of bolting, meshing and lacing as a reinforcing support medium for highly stressed conditions.
