Abstract : Project TRENCHER was an explosives evaluation experiment conducted in clay shale at Fort Peck, Montana by the U. S. Army Engineer Nuclear Cratering Group (NCG). To determine the single-charge cratering performances in clay shale of two aluminized slurry explosives, IRECO DBA22M and Dow MS80-20, 500-pound charges were detonated using a sand and water mixture stemming. Five cratering experiments were conducted with 500-pound charges of DBA22M to determine the effect of different stemming materials on crater volume. Crushed rock, concrete, sand and water, water, and no stemming were the materials used. The test with water stemming gave the largest crater volume. (Author)
