A Study of the Fragmentation of Rock by Impingement with Water and Solid Impactors

Abstract

Based on findings in other research areas it was reasoned that water slugs of substantial size (up to 1/2 lb) traveling at moderate velocities (<800 fps) could impinge on rock with fragmenting pressure. To substantiate this reasoning, a compressed air launching gun was designed and built and an extensive series of impact tests was made on a steel-mounted pressure transducer and on sandstone and limestone targets.
