Field of application
The main application of the OMEGA-BOLT® Expandable Rock
Bolt is temporary rock reinforcement in Mining and Tunneling.
Bonding forces between the friction bolt and the rock mass are
caused by form closure and friction transfer between the bore-hole
wall and the rock bolt, which is expanded by hydraulic pressure.

■ Immediate full load bearing capacity over the complete bolt length
■ Low-sensitive against vibrations caused by blasting works
■ Safe and simple installation
■ No extra building material required for installation
