摘　　要：为探明高头窑煤矿2-3煤层顶板开采水害的影响,运用GIS与AHP耦合的“三图-双预测法”,构建了2-3煤层顶板充水含水层富水性评价模型,综合对比FLAC3D数值模拟、经验公式计算、类比实测多种方法,修正了传统导水裂隙带高度计算公式。在此基础上,复合叠加得到2-3煤层顶板充水含水层涌(突)水危险性分级分区图,并采用数值模拟对高头窑煤矿进行涌水量预测。结果表明:高头窑煤矿中部和西南部突水危险性较高,西北部和东部突水危险性较低。高头窑煤矿的正常涌水量为465 m^(3)/h,最大涌水量为558 m^(3)/h。针对矿井未来面临的水害问题,综合提出了可行性防治措施。In order to find out the influence of water disaster in 2-3 coal seam roof mining in Gaotouyao Coal Mine,the“three-graph and double-prediction method”coupled with GIS and AHP was used to construct the water abundance evaluation model of 2-3 coal seam roof water-filled aquifer.Comprehensive comparison of FLAC3D numerical simulation,empirical formula calculation,analogy measurement and other methods,the traditional calculation formula of fractured water-conducting zone height was modified.On this basis,the classification and zoning map of water gushing(inrush)risk of 2-3 coal seam roof water-filled aquifer was obtained by compound superposition.Numerical simulation was used to predict the water inflow of Gaotouyao Coal Mine.The results show that the risk of water inrush in the central and southwest of Gaotouyao Coal Mine is higher,and the risk of water inrush in the northwest and east is lower.The normal water inflow of Gaotouyao Coal Mine is 465 m^(3)/h,and the maximum water inflow is 558 m^(3)/h.In view of the water disaster problems faced by the mine in the future,the feasible prevention and control measures have been put forward comprehensively.
