Raise boring is a method of constructing a shaft.
How does it work?
A ‘raise’ is where underground entry has already been established. Raised bored shafts can be from the surface or from one level to another underground. The method is remote and does not require people to enter the shaft. It involves: installing a raise borer rig at the top of the planned raise above the existing tunnel or other underground excavation drilling a pilot hole down into the tunnel attaching a reaming head and back reaming to the rig to create the raise, and supporting the completed hole if it is needed by lining or installing ground support. Control measures should be implemented to eliminate or minimise, so far as is reasonably practicable, the risks associated with raise boring. The Guide Tunnelling (Australia): Specific Hazards, Risks and Control Measures – Raise Boring mobile app covers specific hazards, risks and control measures for raise boring.
