摘　　要：非洲某大水铜矿(地下开采)水文地质条件复杂,解析法无法准确刻画。通过研究已有的勘察资料,分析勘察报告利用"大井法"计算涌水量的局限性,并应用数值法进行涌水量预测和评价。选用基于有限元计算的FEFLOW软件进行模拟,经过模型识别,建立合理的矿区地下水天然流场,并分析各源汇项水量均衡情况。最后预测开采条件下地下水流场的变化情况及矿坑涌水量。Analytical method can not accurately solve complex hydro - geological conditions of a copper deposit in Africa （ underground mining）, the author studies the existing data and analyzes the Limitations of ＂ Big well method＂ which is used i.n the survey report. The author use FEFLOW which bases on finite element simulation calculation, and uses pattern recogni- tion, establishes a reasonable mining natural groundwater flow field and analyses various sources and sinks and water balance situation. Finally , it forecasts water inflow under mining condition.
