Abstract

Feasibility of water jet cutting of experimental discontinuities in real, intact rock with reproducible roughness was investigated. Some 60 planar surfaces and undulations were cut in a fine grained sandstone to develop a procedure to control roughness. The final undulating surfaces were natched to form discontinuities with wavelengths of 38 mm with surface roughness similar to No. 100 (sieve size of grains) sandpaper. Cutting of the final surface involves an optimum distance between successive passes of the jet, secondary low pressure washing and an inclined nozzle.
