The safe and economical construction of tunnels, mines, and other subterranean works depends on the correct choice of support systems to ensure that the excavations are stable. These support systems should be matched to the characterstics of the rock mass and the excavation techniques adopted. This expansive text explores the design of rockbolts, dowels, cable bolts and shortcrete for underground excavations in hard rock, and covers key topics including rock mass classification systems, and support design for overstressed rock.
