Abstract [en]

In a follow-up of 12 production blasts in a quarry at the Mrica project on Java, tightly spaced porous bands were found to govern fragmentation to the extent that the average fragment size k50 was nearly independent of the specific charge within the range 0.30-0.56 kg/m³. This finding resulted in a reduction of the running costs for drilling and blasting by 20-40%.

Our Work has given considerable practical benefits and insights into the blasting process, even if the results were of no direct use to check out fragmentation predictions based on models, which was one of our main goals.
