ABSTRACT:
An ice cutting system in which a low density fluid, such as air or exhaust gas, is injected into the cutting region. The injection of the low density fluid results in a more efficient cutting operation, and also reduces the buoyancy of the ice chips resulting from the cutting operation. The reduced buoyancy of the ice chips results in the chips sinking in the slurry surrounding the cutter and being dissipated into the water beneath the surrounding ice.
