ABSTRACT:
A process and apparatus for generating high velocity particulate containing fluid jets is provided which is capable of cutting hard materials such as rock and concrete, and is especially useful for notching blast holes to control the pattern of explosion and material removal. A particulate passage valve is provided to open and close the particulate passage in response to changes in fluid pressure. The apparatus may be portable, durable and lightweight. The nozzle assembly may be inserted directly into the drill hole and is operable in any orientation to issue one or a plurality of particulate containing fluid jet streams.
