When explosives are detonated in rock two things happen, one a shock wave is produced, and secondly gas pressure is formed. The shock wave creates micro fractures around the blast hole; limited to a few diameters of the blast hole, generally speaking thirty feet or less. As the gas expands into these fractures the rock is broken,
