摘　　要：以实际工程为例,将数值方法应用到矿井涌水量的预测研究上。首先对龙固煤矿辅二大巷矿井水文地质条件进行详细分析,将所研究区域的含水层、边界条件以及源汇项进行了概化,建立符合实际情况的地下水流数学模型;然后利用有限差分数值模拟方法,借助Visual Modflow软件实现龙固煤矿辅二大巷地下水位及涌水量预测;最后根据注浆加固方案数值模拟结果,选定合适的顶底板注浆加固方案,模拟注浆加固后巷道涌水量减少为300m3/h,其对应巷道位置的压力水头下降到100 m左右。数值模拟结果为提出合理的注浆堵水加固方案提供了理论依据,对龙固煤矿辅二大巷涌水治理工程进行了指导。Using practical projects as examples,the numerical method was applied to predict water yield of mines.Based on the hydro-geological materials of the second roadway at Longgu mine combined with geological exploration data,a conceptual model and mathematic model were built.The Visual Modflow groundwater seepage simulation software was employed to predict water yield of the second roadway of the mine.The advantages and disadvantages of different grouting designs were compared and discussed according to numerical simulation results.An efficient and reasonable grouting strengthening scheme was proposed based on the analysis for project guidance.
