Through the normal course of operation, mine operators are living situations where blast results need to be measured. It becomes the supervisory group responsibility to select evaluation parameters with appropriated and available techniques. In Mine Selbaie`s case, the authors have selected the following parameters: rock fragmentation, oversize fragments, rock pile movement, grade rupture. It is understandable that each parameter does not have the same influence in a global blast evaluation. To rate the parameters, the authors estimate their influence in relation with the potential cost per ton in different phases of the operations such as: truck loading factor, truck loading time, operation overall efficiency, secondary drilling and blasting, energy consumption at the gyratory crusher. The conference objectives are to outline and define the parameters and their related importance with associated operating cost. As well, this same parameter formula will be used to compare the performance between ANFO and high density mini-prill ANFO product.
