Continuous High-Velocity Jet Excavation. Phase 2

Abstract

The report describes the development of a mobile, fluid-jet, rock fracturing system suitable for performing the field testing required to investigate the feasibility of excavation of in situ rock structures by the action of continuous, high-pressure, fluid jets. Program scope included the design, manufacture and field testing of a mobile, high-pressure, fluid-jet rock fracturing system. General operating parameters of the system, such as jet pressure level, standoff distance, and feedrate, are based on data gained from laboratory testing previously conducted by Bendix under contract to the Bureau of Mines. Testing of in situ rock excavation characteristics was conducted at a field site by traversing the high-pressure jet past the rock face. Supply pressure, traverse speed and standoff distance were the recorded variables.
