Abrasive Water Jet (AWJ) technology is widely used in mining. To explore how rock heterogeneity and natural cracks affect rock fragmentation, a numerical model using the pixel method was developed for jet-induced rock breakage. This method effectively represents rock cracks and improves computational efficiency.
