· Blasting theory dictates that there are 3 principal stages of affecting the rock in a blast. In the first stage high pressure upon detonation expands the blast hole by crushing the blast hole walls (Figure 2). In the second stage compressive stress waves emanate in a 360 degree arc from the hole with a velocity equalling that of sonic wave velocity in the rock. The compressive waves reflect ...
