Abstract

A useful and foolproof method of analyzing explosive phenomena and designing blasts is with information obtained from high-speed, 16mm motion picture photography. Utilizing this information along with the methodologies developed adds confidence to custom and site specific blast designs for use in mining, quarry, coal, utility, construction, research and specialized military applications. The numerical and analytical techniques developed allow a blaster or engineer to evaluate blasting performance, compare explosive efficiencies, optimize millisecond delay timing between detonations, evaluate damage to particular seams of material such as coal, optimize overburden casting, predict explosive energy required to displace toe burdens, compare over-all blast designs, investigate air decks for presplitting and reclamation purposes, and to study general detonation phenomena. Results are based on the analysis of a few hundred films of blasts performed in full-scale production environments. Instrumentation, field set-ups, and specific data interpre-tation are discussed in detail. The presentation is also supplemented with a 10 minute film of selected test blasts.
