ABSTRACT:
A hard compact material, such as rock, is broken by maintaining a column of relatively incompressible fluid, such as water, extending from outside into at least one hole which has been pre-drilled in the material to be broken. A shock wave is generated in the column outside the hole and is transmitted through the column into the hole. Due to the energy of the propagated shock wave, cracks are initiated and driven to a free surface of the material to break same. Breakage by the effect of the shock wave may be facilitated by means of an explosive. The explosive is delivered into the hole prior to the admission of fluid thereinto and is initiated by means of the transmitted shock wave.
