Blasting measurements. The fundamental principle of blast design is most often the distribution of an explosive in the rock, where “distribution” is considered to be a combination of blast pattern and explosive density. Powder factor is the relationship between a rock mass and the explosive used to fragment it; the term “powder factor” can be used to describe either the weight of explosive per unit volume (lb/yd³) or the weight of material blasted per weight of explosive (tons/lb). The weight of
