Abstract

• The possibility of increasing the performance of mechanical tools with the assistance provided by a high-velocity water jet has been explored in the last 20 years. The results of past research have often been controversial and found to vary within a wide range, mainly due to the different experimental conditions adopted. Number of hypotheses have been advanced to explain the variability of the results as well as to disclose the mechanism of water jet assistance. In this paper, after a discussion of the main issues regarding the assistance of mechanical excavation with water jet, the results of an experimental work carried out at the University of Cagliari are illustrated and discussed. The research was aimed both at studying the processes by which mechanical excavation is improved and at quantifying the increment of the excavation performance parameters with water jet. In particular, the mechanisms involved in the rock-tool-water jet interaction have been studied with the goal of putting into evidence the contribution of the jet both as a way to weaken the rock and to increase the stress leading to scale formation. Better knowledge achieved will be useful for the development of the technology up to a commercial scale. (literal)
