ABSTRACT:
Ice is broken with expenditure of less energy by pumping water from beneath the ice and discharging it in large quantities onto the surface of the ice. Breaking stress is provided by the weight of the water and by thermal shock. A conventional ice breaking apparatus can also be run up onto the ice to provide a breaking force in which case friction between the ice and the ice breaking apparatus is lessened by the water.
