摘　　要：针对煤田矿井涌水量预测的复杂性,以山西平朔安家岭井工矿为例,在概化出矿区水文地质概念模型的基础上,建立了安家岭井工矿矿井涌水量预测的地下水三维非稳定流数值模拟模型,并结合矿井生产,按矿井掘进工作面进行了平水期和丰水期两个方案的涌水量预测,获得了各工作面不同时期地下水位分别疏干到4#煤底和9#煤底的矿井涌水量。该方法将矿井涌水量预测和矿井的水文地质结构及矿井生产进度紧密结合起来,具有较高的精度。Aiming at the complexity of predicting the groundwater inflow of mine in coal field,taking the Anjialing Mine in Pingshuo,Shanxi province for example,on the base of generalizing the hydro-geologic structure model of the mine zone,a three-dimensional numerical simulation model of transient flow for predicting the groundwater inflow of Anjialing Mine was built.According to the mine heading face and combining with the mine production,it can estimate the groundwater inflow in average level period and wet period,and acquire the groundwater inflow of each heading face when groundwater level in different periods is down to the bottom of coal seam 4# and 9# respectively.The method of predicting groundwater inflow has high precision,which is combined with the hydro-geologic structure and the production schedule of the mine.
