Rock bolting systems are used to stabilize excavated rock mass in underground mines and tunnelling. Rock bolts are systematically arranged to transfer the load from the unstable surface or exterior of the rock, to the much stronger interior part of the rock. The rock mass can be reinforced by different types of rock bolts. Atlas Copco offers

Rock Bolting Mining Science and Technology

Corrosion is a physical alteration of a material from electrochemical reaction with its environment that often results in reduction of the mechanical properties of that material. Rock bolts are particularly susceptible to corrosion as they can be exposed in their working environment to ground water. Corrosion increases markedly in sulphide
