on the same bench blast, the effects of timing on fragmentation were determined. This analysis provides a representative understanding of timing effects on fragmentation in the field, different from previous blast models which either negate the effects of timing or geology. Four test blasts were conducted at a granite quarry in Talbotton, GA.
