Shallow coal mining in gully regions has resulted significant subsidence hazards and increased the risk of surface water inflow into panels, compromising sustainability management underground resource exploitation. In this study, chain disaster process caused by shallow seam heavy rainfall is quantitatively analyzed. The findings reveal that leads to formation caved fractured zones vertical direction overlying rock. zone can be further classified a compression shear horizontal direction. responsible for generating deformations, intercepting runoff, potentially triggering landslides, necessitating crack landfill treatments, which are critical promoting sustainable practices. HEC-RAS program was utilized integrate annual maximum daily data across different frequencies, enabling establishment dynamic assessment model barrier lakes. Numerical simulations based on unsaturated seepage theory provide insights infiltration behavior study area, indicating increase saturation within lower terrain. Precipitation found enhance rock mass, reducing matric suction areas. Finally, discussed, recommendations managing stages proposed. This offers valuable reference prevention control damage under conditions regions.
