  • In order to study the influence of the different locations between the grouting hole and the fractures of surrounding rock on the rock mass splitting characteristics, RFPA-flow software is used to establish the grouting hole and the surrounding rock fracture intersect or not two models whether the intersection, the whole process of fissure initiation, propagation and penetration was numerically simulated. The results show that when the grouting hole intersects with the fractures, the slurry is filled first, and when the stress reaches the crack initiation pressure, the fractures are cracked and gradually expanded. When the grouting hole does not intersect with the fissures, the grouting hole and the one end of the crack fissure which is closer to the grouting hole first split and extended until the inter-connected. Then, the fracture is filled with slurry, continuously fractured.
