Cable bolting is an established technique used extensively for reinforcement of the rock mass adjacent to surface and underground rock excavations. Cable bolts are long, fully grouted, un-tensioned reinforcing elements. The
objective of cable bolting is to improve the shear and tensile strength of the rock mass.
Although there are many variations of this procedure and related products, such as specialized cables and grouts, ultimately the grout must be a high shear thixotropic mixture that will stop flowing once the pumping pressure is relieved, which will provide the required strengths and in situ expansion.
