Shelters and some drifts in mines should be designed for rock burst induced by detonations. Absorption of released momentum is studied experimentally for both steel fibre and mesh reinforced shotcrete as well as rock bolts anchoring the shotcrete. Even if the shotcrete exhibits a bonding failure primarily, it cannot absorb a significant momentum because the failure mechanism is local. A rock bolt can absorb the momentum if it plasticizes over a reasonable length. A bolt design is demonstrated which gives the bolt such properties.
