Sažetak
Predictions and analyses of blasted rock mass fragmentation have increased in importance, as primary fragmentation can significantly decrease the cost of crushing and secondary breaking, on condition that the correct geometry of drilling and blasting parameters is used. The article shows the estimation of fragmentation using the "SB" program, which was created by the authors. It also shows calibration of factors given for the quarry "Očura". The resulting calibrated value of the rock enables the quality prognosis of fragmentation in further blasting works with changed drilling geometry. It also facilitates simulation in the program to optimize blasting works in order to get the desired fragmentations of the blasted rock mass.
