Abstract
Results from an experimental program to examine mining of native copper ore with high pressure, continuous fluid jets are given. Variables that will influence the cutting rate and energy consumption of the mining process are considered. The variation of cutting depth and specific energy with both jet traverse speed and jet pressure is shown. Estimates are made of the reduction in energy consumption by adding mechanical cutting assistance to the excavation system.
