Abstract
This paper describes the evolution of water-jet-assisted roadheaders and the benefits to be gained by their use. Testing has shown that although significant reductions in respirable dust are achieved at water pressures approaching 3,000 psi, there appears to be no effect at pressures above that level. A reduction in bit wear and frictional sparking were also noted, but the optimum water pressures to obtain these benefits have yet to be defined.
