The authors say there is more to proper blasthole design than sequencing holes. Timing is one of the most important blast design variables. Timing controls the fragmentation size, piling of the broken material, maximum vibration level, airblast, flyrock, backbreak, endbreak and general overbreak. The authors explain how each of these items is controlled by timing.
