This report discusses results of the development and testing of a prototype hydraulic mining machine that uses a water jet with solid particles added. The study disclosed that solid particles could be injected into a high-velocity stream without great difficulty at reasonable feed rates and without significant deterioration in the downstream jet. The addition of particles did not appear to improve the cutting ability of the jet compared with the use of water alone. The cutting ability appeared to increase as the mass of the particle was increased.
