Abrasive water jet rock breaking method with secondary impact effect and composite abrasive particle
This invention discloses an abrasive waterjet rock-breaking method with a secondary impact effect and composite abrasive particles. The composite abrasive consists of a core, an intermediate layer, and an outer shell. The method uses a nozzle to accelerate the jet and impact the rock. First, the composite abrasive particles as a whole undergo an initial impact, forming a damaged zone. Subsequently, the impact load causes the outer shell and intermediate layers of the particles to fracture as designed, releasing the core particles. The core particles, driven by the high-speed water flow, precisely impact the aforementioned damaged zone a second time. The intermediate layer has a lower body strength than the outer shell and core, and its interfacial bonding strength with adjacent layers is precisely designed to ensure stability during transport, while reliably failing during the first impact to release the core. This invention achieves sequential energy utilization through a synergistic "impact-release" mechanism, significantly improving the rock-breaking efficiency of hard rock and the utilization rate of abrasive kinetic energy.
