Abstract

"By means of the resistance-element, or probe-wire, detonation-velocity measurement technique, explosive reactions from various blasting agents were studied. To reduce the number of variables, only standard AN-FO 94/6 mixtures were used, as are commonly employed today in constructions and mining operations. Accuracy of the data obtained was excellent, and the method proved itself not only relatively simple to operate but versatile in providing considerable information under many testing conditions. Studies of test records revealed the presence of a time-lag frequently occuring [sic] after primer detonation. Environmental factors such as confinement, charge diameter, primer size and energy content, and surface coatings on ingredients were then analyzed to determine their influences, if any, on resulting time-lags. The results indicated definite relationships ... Most significant of all, however, was the fact that the ignition time-lag apparently had a strong influence on the degree of total maximum energy released"--Abstract, pages i-ii.
