摘　　要：为准确评价、预测新集矿区11-2煤层顶板突水问题,利用矿区近些年积累的水文地质资料,选取了断层强度、断层交叉点与尖灭点、导水裂隙带高度、关键层厚度、含水层厚度、隔水层厚度、砂泥比8个因素作为顶板突水主控因素进行了深入的探讨。运用GIS空间分析功能建立了主控因素专题图,并对专题图数据进行归一化处理,结合AHP层次分析法确定了各主控因素影响权重。通过对归一化数据与权重值的空间复合叠加,获取了新集矿区11-2煤层顶板突水危险性评价分区模型,评价结果与矿区实际地质条件与突水点相吻合,可为矿区今后煤层开采与水害防治工作提供参考依据。In order to accurately evaluate and predict the roof water inrush problem of the 11-2 coal seam in the Xinji Mining Area,the hydrogeological data accumulated in the mining area in recent years were used to select the fault strength,fault intersection and pin-out point,water-conducting fracture zone height and key layer thickness,the thickness of the aquifer,the thickness of the aquifer,and the sand-mud ratio were discussed as the main controlling factors of the roof water inrush.Using the spatial analysis function of GIS,a thematic map of the main controlling factors was established,and the data of the thematic map was normalized,and the influence weight of each main controlling factor was determined by combining the AHP analytic hierarchy process.Through the spatial composite superposition of normalized data and weight values,a zonal model for water inrush risk assessment on the roof of the 11-2 coal seam in Xinji Mining Area was obtained.Provide reference for coal seam mining and water hazard prevention and control.
