The Design of an Experimental High Energy Impact Tunneler
Abstract
The research program emphasized the field testing of a medium energy impact breaker IMP-1000. Quantitative data were obtained on the effect of the variation of blow energy, blow spacing and tool point geometry on the amount of rock broken during the excavation. Motion picture records and other qualitative observations were made. In addition to the field work, Demon 300 tool was repaired for future use, an impactor capable of delivering 50,000 ft. lb/blow was sized up and laboratory rock tests were conducted to obtain qualitative data on edge fracture.
