Fragmentation Studies with Large Flaws
This lecture describes results obtained when investigating fragmentation achieved in models which contained large flaws. Figure 1 is a photograph of a working bench face in the Pinesburg limestone quarry located near Hagerstown, Maryland. The segmentation seen in Figure 1 is typical of rock found in quarry locations. Much of the segmentation in a quarry bench is blast damage incurred in fragmenting the material that was removed in previous shots. These detonations loosen up the joints and faults that are present in the formation, but not to such an extent that the material can be removed.
