Abstract: In response to water hazard threats during coal mining at Sangbei Coal Mine due to complex geological conditions and a unique hydrogeological environment, this study aims to investigate the hydrogeological conditions of the mining area, assess water hazard risks associated with pressurized mining, and establish a scientific prevention and control technical system.Methods such as geological exploration, hydrogeological testing, and water inrush coefficient calculations were employed to analyze aquifer characteristics.Integrated geophysical and drilling exploration techniques, along with zonal grouting treatment, were utilized to establish a 3D monitoring and early warning system.The study identified a three-layer aquifer system in the mining area, with the Ordovician karst fissure water being the main aquifer.The water inrush coefficients for the No.3 and No.11 coal seams were 0.021～0.097 MPa/m and 0.038～0.210 MPa/m, respectively, indicating a higher water hazard risk for the No.11 coal seam.An integrated prevention and control technical system of “exploration-treatment-monitoring” was constructed and successfully applied to the 1103 working face.
