How fragmentation analysis can assist in blasting - Quarry

2019-2-8  How fragmentation analysis can assist in blasting. The basic aim of all blasting operations is to fragment the rock mass in a suitable granulometric distribution, and obtain a shot pile formation and bulking of the material. The resulting fragmentation can significantly affect later stages of the operation. In this regard, successfully loading ...
