This study presents a comprehensive numerical analysis of dynamic rupture and fault-induced seismic risks in deep roadway excavation environments, focusing on near-fault conditions. A quantitative assessment was conducted for faults within 5 m of the roadway, a critical range for evaluating heightened seismic risks. Our results demonstrate that within this proximity, fault slip and seismic moment increase significantly, with peak fault slip reaching 17.1 mm and seismic moment exceeding 3.9 × 10
