摘　　要：钻井是砂岩型铀矿床地浸开采的主要手段,合理设计及高质量施工是地浸矿山稳定生产、连续运行的保证。通过运用GMS地下水模拟软件,建立"一抽一注"模型,在钻井剖面上模拟浸出液在2种高度垂向过水断面的渗流范围,使钻井设计和施工工艺更趋合理。Drilling well is the main means for sandstone type uranium mining,and reasonable design and high quality of drilling well construction are assurance of the stable production and continuous operation on uranium mine.The seepage range model of one drawing well and one injecting well on two kinds of vertical cross section length are established by using of GMS software for groundwater simulation,which make design and construction more reasonable.

关 键 词：钻井 切割建造过滤器 垂向过水断面 地下水模拟 渗流范围
