Project Description

A rock bolt for use in areas prone to rockburst

The Rock Burst Bolt is a pre-tensionable, post-groutable and deformable rock bolt especially engineered for use in areas prone to rock burst and other large deformations of rock mass. The bolt consists of a rod with specially formed surface features and an expansion anchor. The unique combination of pre-tensioning and post-groutable features reduces the rock burst effect and gives immediate support for fast excavation. The post-groutable feature ensures robust long term stability and corrosion protection.
