Development of High-Pressure Water Jet Equipment for Underground Application of Excavating Energy Materials

• Description:
  A high-pressure intensifier system was designed, constructed, and field tested as part of a program to determine the feasibility of applying high-presure water jets on conventional mechanical rock excavation equipment to increase advance rates. A high-volume swivel, capable of transferring the high-pressure water to a rotating cutterhead, and a manifold system for locating and protecting the jets on the cutterhead were also developed. An economic analysis was undertaken to determine the degree of cost benefits attainable from increased advance rates. Significant savings were seen to be possible. It was concluded that the basic concept of combining a water jet capability with a mechanical excavating machine is definitely possible. [Description provided by NIOSH]
