Rock Disintegration by Liquid Jets

Abstract

The purpose of the research program is to optimize the efficiency of rock disintegration by pulsed high pressure water jets. The high energy pulsed jets are produced using an exponential nozzle (U.S. Patent 3,343,794). Actuation is provided by a steel piston, 3.25 inches in diameter, fired from an air gun. Results to date cover only the suitability and calibration of the air gun. The nozzle assembly is scheduled for delivery during the second half of the contract period, and the rock fracture tests will be conducted in that period. It is concluded that the air gun actuator is suitable for the intended use. Design data for the nozzle are presented.
