Rock Blasting

Firstly, the shock wave creates and expands the micro fractures in the rock mass and initiates the breaking process. Then the gas, expanding the drill hole under very high pressure, exacerbates the damage with the creation of radial cracking, as shown on this figure. The gas pushes on the rock to open and expand the cracks.
