On the basis of maintaining the original number of fissures, new fissures and holes are added to explore their effects on the rock mass. Combined with discrete element numerical simulation, the microscopic characteristics of multi-fissure samples and borehole samples are analyzed. The research results indicate that as the fissure dip angle increases, failure occurs gradually along the existing fissures, while the crack development in the borehole samples is mainly concentrated around the holes, and the boreholes have a greater impact than fissures.
