Timing effects on fragmentation - Mining and Blasting

experiments, fragmentation optimization requires delays of few milliseconds per meter of burden. In view of the findings, which agree with previous published work, the current trend of selecting fast firing times for fragmentation optimization is questioned. Introduction Timing of detonation has long been of interest to blasting.
