To predict hazardous zones in underground roadways under the action of slope landslides and theirimpacts in Shilu Iron Mine, the dynamic mechanical properties of ore and rock under equivalent impact air pressurewere studied through split Hopkinson pressure bar（SHPB）impact tests. Combined with the particle flow code（PFC）discrete element method, a study on slope landslides at Shilu Iron Mine was conducted, and the meso⁃mechanicalcharacteristics of landslide impact and their influence on underground roadways were analyzed. The research indicatesthat when the rock mass is homogeneous, the failure mode of the ore and rock is V⁃shaped. When the rock mass isheterogeneous, and the height⁃to⁃diameter ratio α=2, the ore and rock exhibit a strong brittle failure mode, and thespecimens remain relatively intact after failure; the impact length is proportional to the degree of specimen fragmentation.Slope landslides are induced by the deformation and failure of shallow rock layers, which cause the failure of internalrock particles, primarily sliding along the direction from the slope crest to the toe. The landslide surface is smooth, witha predominant slip velocity of 4.5 m/s. The final natural angle of repose of the slope is 20°. The internal displacement ofthe landslide mass ranges from 100 m to 200 m, with a maximum displacement reaching 310.6 m. The −45 m level roadwayis at risk of collapse, while the −60 m and −75 m level roadways are safe. This study provides a useful reference forunderstanding the influence of landslide impact on the stability of underground roadways in mining areas.
