##### Abstract [en]

Kuznetsov's Model is a commonly used equation for estimation of mean fragment size. This model is a function of three factors; rock mass properties, blast geometry and type of explosive. To evaluate the Kuznetsov model, ten blast sites were studied in the Sungun Copper Mine, Iran. The same explosive, ANFO, was used for all blast and the blasthole geometry was the same in all cases. The Kuznetsov model underestimates the measured mean fragment size in all cases. Since the blast geometry and the explosive were the same for all blasts, it can be concluded that the differences arise from an incomplete description of rock mass properties inherent in the rock factor in the Kuznetsov model. Modifying the multiplier 0.073 instead of the usual 0.06 resolves the problem
