EFFECT OF HIGH SPEED WATER JET STREAM ON ROCK BREAKING: POTENTIAL APPLICATION IN TUNNELING OPERATION (2ND REPORT)
Rock breaking with high speed water jet stream has been studied mainly through experiment. The experiment has been performed with the 3rd-stage pressure intensifier type experimental equipments which has the maximum jetting out pressure in nozzle from 5,000 kg/sq cm up to 17,000 kg/sq cm. From the results of that experiment, the rock breaking effect of this high speed water jet stream is discussed.
