Alimak Raise Excavation

Raise development using a Mechanized Raise Climber (Alimak) is a preferred method for developing escapeways, ventilation raises, ore/waste passes, and slot raises in underground mines.

Manroc is a world leader in raise development, recognized for our high safety standards in underground mining.

How it works

Drilling, loading and blasting are all performed from the platform of the Alimak, which is adapted to fit the precise dimensions and shape of the raise. The raise miners remain under the safety of our unique two-post canopy system that was developed in order to ensure protection while working on the platform. The Alimak unit implements a rack and pinion rail, designed to carry air and water to the work face.
