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 sys-tem.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 treat-ment,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 haz-ard risk for the No.11 coal seam.An integrated prevention and control technical system of"exploration-treatment-monito-ring"was constructed and successfully applied to the 1103 working face.关键词
