  • Description:
    This paper presents an overview of the water-jet-assisted rock cutting research being conducted at the Bureau of Mines Pittsburgh Research Center. Findings indicate substantial reductions in airborne respirable dust using directed 3,000- to 9,000-psig water jets to assist mechanical cutting tools. In addition to dust reductions, there is a strong potential for longer cutting tool life attributed to jet lubrication and cooling of the cutting edge; reduced tool forces at the same depth of cut attributed to jet lubrication, precleaning of the tool path, and lubrication and propagation of mechanically induced rock cracks; and reduced occurrence of frictional ignitions attributed to jet cooling of both the cutting tool and rock surface. Research to date has established confidence in the concept of water-jet-assisted rock cutting, inferred some limitations, and highlighted specific areas requiring ongoing effort.
