NTIS: PB/243-733 :104 pages
Results are described of a design study investigating the feasibility of using high-pressure water-jet cutting in continuous mining of coal in underground mines. In the report, a design concept is developed in which eight water jets would be mounted on a modified Goodman 968 loader with standard gathering headarms and drive. According to the design, four double acting intensifiers feed the eight jets at 50,000 psi with a flow rate of 28.8 Gpm. A traversing mechanism is described that would move the jets across the face at 30 ips in a programed cutting pattern.
