摘　　要：涌水量计算常用的方法主要为比拟法、解析法和数值法等,前两种方法简便,数值法比较复杂,计算精度较差。为了提高矿井涌水量预测精度,运用达西定律基本原理,采用空间分析平台,对矿井规划采区和井筒涌水量进行了预测,鱼卡三矿矿井筒涌水量预测值2831.69 m3/h,相对误差5.9%。表明该方法计算精度高于数值法,且能计算任意形状的"大井"的矿井静涌水量和动涌水量。Water quantity calculation methods include analogy method, analytical method and numerical method, the first two method is simple, the numerical method is more complex, with unsatisfactory calculation accuracy. In order to improve the prediction accuracy of the mine water inflow and provide the technical data for mine water prevention work, with the basic principle of Darcy＇s law in this paper, the planning of mining area and mine inflow shaft were predicted, the predicted water inflow value was 2831.69 m^3/h, the relative error 5.9%, the comparison showed that the technology is superior to the accuracy of numerical method, and can calculate dynamic inflow of water inflow in arbitrary shape shaft.
