摘　　要：在充分认识和掌握了研究区水文地质条件的基础上,建立了与实际相符的概念模型,运用目前流行的地下水数值模拟软件FEFLOW对其进行模拟。结合模拟结果,重点分析了导水裂隙带的高度、裂隙带的渗透系数、Ⅵ煤顶板砂岩裂隙含水层的渗透系数对涌水量的影响,确定了主要影响因素,对在导水裂隙带影响下的涌水量预测理论进行了丰富。Based on fully understand and master the study on the basis of the hydrogeological conditions, consistent with the actual model is established. The numerical simulation software, named FEFLOW, is used to simulate this model. Meanwhile analyses how water inflow is affected by the height of diversion fissure zone, the permeability coefficient of fissure zone and the permeability coefficient of VI# coal roof sandstone fissure aquifer. Reasonable and reliable conclusions are obtained. It provides the reasonable theory about the water inflow prediction under influence of diversion fissure zone.
