摘　　要：本文充分利用地表及地下井巷揭露资料，配合物探成果推测深部水文地质条件。利用同位素^（１８）Ｏ分析结果量化各种水体补给量，然后利用数值模型检验、校正上述成果，优选水文地质参数并进一步预测深部中段涌水量。考虑到模拟过程中某些未知因素，或未来开拓过程中工程措施的影响，本文对预测结果进行了必要的讨论和修订。The hydrogeological condictions of the deep rock at San shan island gold mine is examined from the observation data of exploratory wells and drift. The recharge water quantity from each water body(including sea water、salt water in the deep rock and fresh water in Quaternary deposits)is determined using the laboratory test on isotope 18O.Numerical model and nonlinear porgramming method are used to test and calibrate the previous examination results,and to determine hydrogeological paremeters.The mine water flow in the next digging operation is also predicated by numerical model.A sufficient numerical analysis,in which the deviation between practical and predicated water flows may exist due to some unknow information and different digging methods,is presented in this paper.
