摘要
In this study, a well-designed experimental setup is used to determine the rock-breaking performance of a high-pressuresupercritical carbon dioxide (SC-CO2) jet. Its rock-breaking performance is first compared with that of a high-pressure water jetunder the same operation conditions. The effects of five major factors that affect the rock-breaking performance of the high-pressureSC-CO2jet, i.e., the nozzle diameter, the standoff distance, the jet pressure, the rock compressive strength and the jet temperature areexperimentally determined. The experimental results indicate that the rock-breaking performance of the SC-CO2jet is significantlyimproved over the high-pressure water jet. It is also found that the rock-breaking performance of the SC-CO2jet is improved with theincrease of the nozzle diameter or the standoff distance, until the nozzle diameter or the standoff distance reaches a certain criticalvalue and after that it begins to deteriorate. The rock-breaking performance of the SC-CO2jet improves monotonically with theincrease of the jet pressure, while it shows a monotonic deterioration with the increase of the rock compressive strength. In addition,it is found that, under the same working conditions, the SC-CO2jet can always provide a better rock-breaking performance than thesubcritical liquid CO2jet.
