摘　　要：查明矿山地下水流动规律和准确的进行涌水量预测对于矿山生产非常重要。由于矿山水文地质条件比较复杂,特别是在岩溶区含水层中发育较多的岩溶管道和存在人工巷道的情况下,传统理论的建模方法主要基于钻孔资料,因此无法精确刻画该问题。本研究将基于钻孔资料,水文地质剖面图与人工钻孔方法,采用GMS软件,建立研究区的含水层结构模型。结果表明本研究的建模方法精度远高于钻孔建模方法。该方法可以精确地将岩溶管道和人工巷道表达出来,为地下水与溶质运移模拟提供了理论基础。Identification of mine groundwater movement and accurate outflow rate prediction are critical to mine production.Due to complicated mine hydrogeological conditions,especially under conditions of many karstic channels developed in karst region aquifer and artificial roadways.While modeling methods from traditional theory are mainly based on drilling data,thus unable to accurately describe the issue.The study is based on drilling data,hydrogeological sections and manual drilling method,through GMS established study area aquifer structure model.The result has shown that the accuracy of this model is well above models from drilling modeling.The method can show karstic channels and artificial roadways accurately,and provide theoretical basis for groundwater and solute migration simulation.
