One way to optimize the rock blasting operation is to conduct detailed structural analysis of the rock mass. For this, it makes use of algorithms that allows analyze the degree of fragmentation by changing the geometrical and geomechanical parameters, such as the equations proposed by Kuznetsov (1973), used for studying the interaction between explosive and rock. In this context, this study aimed to compare the classical methodology for the fragmentation of rocks with the method of fragmentation analysis by image. The study was done through field data provided by Herval Quarry which were analyzed for evaluation of fragmentation through images of blasted material muck piles. Were analyzed the P50, P80 and P100 of granulometric distribution curves. The optimization of blasting was done by adjusting the mesh of the fire plan (burden and spacing) and stemming length.
