Analysis of Rock Fragmentation under High Pressure Water Jetting

Abstract

Abstract: High efficiency rock fragmentation is a fundamental technique in the drilling engineering. This technique is critical in the area of improving the rock fragmentation ratio, reducing the drilling time in the rock mass as well as reducing the drilling cost. This paper summarized the basic theories of rock fragmentation by using the steady high pressure water jetting technique. The mechanism and process of rock breaking are also analyzed. The water jetting parameters on the rock (using sandstone as a target) breaking are discussed.

Key words: High Pressure Water Jetting, Mechanism, Process of Rock Fragmentation, Rock Breaking Effect
