摘　　要：深部煤层开采时充水水源主要源于承压含水层,由此造成的矿井水害严重影响煤矿安全。以范各庄煤矿北翼为例,针对5煤采空区和水文地质条件,划定地质“天窗”,利用GMS(Groundwater Modeling System)数值模拟软件建立研究区域地下水流场模型;基于第1阶段放水实验数据对模型进行识别,采用第2阶段放水实验数据进行模型验证,对研究区内的地质“天窗”使用参数分区进行处理;对12煤2022工作面回采过程中的涌水量以及5煤~12煤层间砂岩裂隙承压含水层的地下水流场进行了模型预测。结果表明:随着工作面的回采,工作面涌水量逐渐增大,以采空区为中心的降落漏斗逐渐扩大,最后影响至5煤层顶底板隔水层地质“天窗”。The source of water filling mainly originates from the pressurized aquifer in mining deep coal seams,which seriously affects the safety of coal mine.Taking the north wing of Fangezhuang Coal Mine as an example,the geological“skylight”was delineated according to the 5#coal seam gob and hydro-geological conditions,and the groundwater flow field model in the study area was established by using the GMS(Groundwater Modeling System)numerical simulation software;the model was identified based on the first stage water discharge experimental data,and the second stage water discharge experimental data was used to verify the model,and the geological“skylights”in the study area were processed using parameter zoning;the water inflow in the mining process of 12^(#)coal 2022 working face and the groundwater flow field of sandstone fissure confined aquifer between 5^(#)and 12^(#)coal seams are predicted by model.The results show that with the mining of the working face,the water inflow of the working face increases gradually,the drop funnel centered on the goaf expands gradually,and finally affects the geological“skylight”of the water-resisting layer of the top and bottom of the fifth coal seam.
