Guide Tunnelling (Australia): Specific Hazards, Risks and Control Measures – Ground Freezing Mobile App
Ground freezing is used in tunnelling, sinking shafts in very soft and wet ground conditions and where there is free running saturated sands.
How does it work?
It can also be used for temporary ground support and preventing groundwater flow. The wet ground where the shaft is to be sunk is artificially frozen, excavated as though it were solid rock, then lined and sealed before being allowed to thaw. The process can also be applied to horizontal development. Specific hazards and risks arise from the reduced temperature. Control measures should be implemented to eliminate or minimise, so far as is reasonably practicable, the risks associated with ground freezing The Guide Tunnelling (Australia): Specific Hazards, Risks and Control Measures – Ground Freezing mobile app includes specific hazards, risks and control measures - ground freezing.
