Cablebolting in Underground Mines

Cablebolts are high capacity flexible tendons composed of multi-wire strand
which are normally installed and grouted in drilled holes at regular spacings to
provide reinforcement and support of excavations in rock. They can be cut to any
length and installed in single or multi-strand configurations and can be installed
from small adits and tunnels (drifts) where limited clearance would preclude the
use of rigid tendons.
The last decade has seen a dramatic increase in cablebolt usage in underground
mining. There has been a corresponding increase in associated research around the
world.
