Frozen Ground Implement
Abstract
The report presents information on an evaluation of commercial-type liquid carbon dioxide blasting cartridges for use in excavation of frozen ground. The purpose was to develop a portable kit to aid in the construction of foxholes in frozen ground without the use of explosives. The kit consisted of an engine-driven hand-held rock drill, and the blasting cartridges. Tests were conducted in both shallow frozen and deep (perma-frost) frozen ground. The results were good in shallow frozen ground. Good results were not achieved in deep frozen ground, because proper techniques or devices were not used to keep the cartridges from ejecting from the bore hole. The requirement was withdrawn, and additional development/testing were not conducted.
