ABSTRACT:
A hard compact material, such as rock, is broken by forcing an elongated mass body of relatively incompressible fluid, such as water, against the material to be broken. The mass body is caused to impact the material at a momentum necessary for breaking the material. The momentum is generated by supplying the fluid to a storage chamber against the effect of a thrust load acting upon the fluid in the storage chamber. When a sufficient amount of fluid has been supplied the fluid in the storage chamber is forced toward the material to be broken by the effect of the thrust load.
