In confining pressure conditions, due to the simple jet or abrasive jet cavitation erosion crushing capacity increases with confining pressure decreases rapidly

If the energy of the jet can be fully utilized, then the erosion crushing capacity will further increase operational effectiveness will be greatly enhanced. In addition, with the development and utilization of marine resources accelerates, the deepwater drilling become an important direction of development at home and abroad, deep  grinding wheel  technology more  polycrystalline diamond  and attention. In confining pressure conditions, due to the simple jet or abrasive jet cavitation erosion  synthetic diamond  increases with confining pressure decreases rapidly, so the abrasive water jet cutting capacity to be improved. , Proposed the use of BP neural network to predict the depth of abrasive jet perforating rock breaking new method. By comparing the predicted values ​​with the experimental findings, the prediction accuracy of the method fully meet the engineering requirements for on-site applications provide theoretical support.
