APPARENT CRATER STUDIES

摘要

Dimensions and geometry of the Dugout crater, produced by the detonation of a row of five 18,144 kg nitromethane charges in basalt, were analyzed. The linear portion of the crater was 41.6 meters wide and 10.7 meters deep, 36% wider and 53% deeper than the Pre-Schooner Alfa crater, which was produced by the detonation of an identical charge at the same depth. Lips on the sides of the crater were massive, and were about twice as high as those of the Alfa crater;on the ends of the crater the lips were slightly smaller than the Alfa crater lip. The volume per charge of the linear section of the crater was 70% greater than the volume of the Alfa crater. The greatest range of the rock missiles perpendicular to the row of charges was 2.5 times the greatest missile range from the Alfa detonation.
