This book was released on 1973 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Project Diamond Ore Phase 2A consisted of the detonation of three 10-ton charges of aluminized ammonium nitrate slurry at different depths of burst (DOB) and stemming conditions near Fort Peck, Montana, in October 1972. The purpose of the investigation described herein was to determine the effectiveness of the three craters as barriers to the performance of an M48A2 tank. The unstemmed charge at optimum DOB that formed crater 2A-1 created a marginal condition of 'go-no go' for the tank. The stemmed charge at optimum DOB that formed crater 2A-2 and the stemmed charge at approximately one-half optimum DOB that formed crater 2A-3 created definite barriers to the tank. There were indications that a more effective barrier for the tank was produced by the stemmed charge at approximately one-half optimum DOB than by the stemmed charge at optimum DOB. The time required for a D-9 tractor to make crater 2A-3 passable for the M48A2 tank was 1 hour.

This book was released on 1974 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: On Diamond Ore shot 6M, a 17 ton charge of nitromethane located at a depth of burial of 5.85 meters (19.2 feet) in Bear Paw clay shale, Physics International Company measured (1) shock velocity up the unstemmed hole from charge surface to the ground surface, (2) stress at three locations along two radial lines 90 degrees apart, (3) horizontal and vertical particle velocity at one location along each radial line, and (4) airblast overpressures at the ground surface. Shock velocity up the unstemmed hole was twice the predicted value. Peak stresses were lower than predictions. Difficulties were encountered in measuring particle velocity because accelerations were higher than expected. Surface-level peak overpressures were greater than predicted for a buried TNT charge and less than the Sprint in-cell measurements.

Book excerpt: Airblast measurements were made with two gages at each of three separate distances from the 20 cratering shots of Project Diamond Ore, Phase IIB. There were seven unstemmed single-charge shots, three unstemmed row-charge shots with three charges, three stemmed row-charge shots with five charges, two stemmed row-charge shots with three charges, and four shots with charges at or near the ground surface. Weights of individual charges ranged from 80 to 34,000 lbs. The unstemmed single-charge shots varied in depth of burial and permitted the attenuation of airblast parameters to be defined as a function of these depths. No comparison of the stemmed row-charge airblast with that from stemmed single charges was possible because no single charges have been fired in the same medium. No comparison was made for single-and row-charge unstemmed detonations because of differences in explosive, charge size, charge burial depth, and open-hole diameter. Differences in airburst from surface and near-surface bursts resulting from variances in charge position were less than differences caused by meteorological changes on the days the shots were fired. The single-charge data provided a further opportunity to evaluate the usefulness of airburst suppression with charge burial depth and stemming as an analog to suppression of radioactivity from nuclear cratering explosions, Airblast gas-venting impulse fractions out of the ground were in agreement with those obtained on one shot for radioactivity fraction using a radioactivity simulant. Airblast as an indicator of suppression has the advantage of being less dependent on local wind conditions.
