AN OSCILLATING WATERJET DEEP-KERFING TECHNIQUE

Cutting deep slots in rock with a waterjet requires a nozzle configuration that can cut a kerf wide enough for the nozzle assembly to enter. A tool for cutting such slots, which utilizes an oscillating mechanism, has been developed. This device uses only static seals and is inherently more reliable than a rotating device. Deep kerfing with waterjet should have applications in the areas of tunneling, mining, quarrying and trenching. The deep-kerfing tests have been conducted on a variety of rock. Based on test data, a physical model that can predict cutting rates has been developed. This model permits the study of various applications of deep-kerfing nozzles without requiring expensive experimental test programs. /Author/TRRL/
