Abstract:
Stress, particle velocity, and acceleration data were obtained from a 140-ton nitromethane row-charge detonation in a saturated clay-shale. The charge row consisted of two 40- and three 20-ton spheres first and fourth charges were 40 tons extending S 11 W from the Pre-GONDOLA I Charlie crater on an 80-foot spacing first charge 105 feet from crater center. The primary instrument line stress and particle velocity gages extended S 79 E from the center charge G with gage stations 100, 150, 200, 300, and 400 feet from G. Gage depths were 10 and 50 feet except the 400-foot station which was gaged at 50 feet only. Acceleration measurements were made on the slopes of the Pre-GONDOLA I Delta and Charlie craters and at the Control Point CP.
