Project Description

Increasing a rock bolts ability to absorb energy

Dynamic Rock Bolt Cylinder (DRBC) is a ground control technology for high deformation environments in mining and tunneling. The solution is a deformable cylinder that can be mounted on a rock bolt head or anchor, to increase its ability to absorb energy. Deformations will take place in the deformable cylinder rather than the stem of the bolt, which also makes it easy to observe the degree of deformation.
