摘　　要：针对铁法集团大强煤矿1号煤可能存在的顶板涌(突)水危害问题,运用基于地理信息系统(GIS)的层次分析法(AHP)型"三图–双预测法",通过对含水层厚度、岩心采取率、单位涌水量、渗透系数、断层等5个主控因素的综合分析,在建立煤层顶板充水含水层富水性分区图的同时,对开采煤层的顶板安全性进行评价及分区。在以上研究的基础上运用GIS多源地学信息复合叠加原理,提出了1号煤顶板涌(突)水条件综合分区的划分方案。根据综合分区结果,运用Visual Modflow软件对即将开采的2-202工作面和三采区进行了涌水量预测。To evaluate mine roof water inrush in coal seam No.1 in Daqiang mine of Tiefa Coal Group, the AHP-type “three maps-two predictions” method based on GIS is employed. Through comprehensive analysis of 5 geologic factors such as the thickness of aquifers, total core recovery, volumetric flow rate, permeability coefficient and faults which influence the water abundance of the roof of coal seam No.1 in Daqiang mine, the water-richness distribution maps of aquifers in coal roof were obtained, and the research on safety division of the breaking zone was conducted. The final comprehensive division program on water bursting conditions of coal seam No.1 in Daqiang mine was presented through overlapping of multiple source geo-information on the basis of the above studies. Finally, water bursting inflow of mining faces 2-202 and the 3rd mining area was predicted by utilizing advanced professional software Visual Modflow.
