High-pressure water jet rock breaking theory and its application in underground engineering basic research

Traditional abrasive water jet technology pump pressure, high cost, energy consumption, bulky and sophisticated system, not suitable for the application of post-disaster rescue scene. By the National Natural Science Foundation of Innovative Research Groups fund "high-pressure water jet rock breaking theory and its application in  abrasive wheels  engineering basic research" and the nation-building project level Graduate Students relying on the traditional premixed abrasive water jet  synthetic diamond  proposed a new type of hydraulic squeeze-type abrasive water jet formation mechanism and equipment for research; built hydraulic squeeze-type abrasive water jet system model; carry out the system's abrasive jet formation mechanism and abrasive nozzle wear mechanisms visualization experiments research;
