摘　　要：矿坑涌水是矿产安全开发的主要威胁,如何精确地预测开采涌水量直接关系到矿山开发远景和生产安全。以某拟建铁矿为例,建立地下水系统水文地质概念模型和数学模型,并对地下水流模型的参数进行识别校正和敏感性分析,采用有限差分数值模拟方法,评价矿体-400、-500、-600m共3个开采水平的矿坑开采涌水量。计算结果表明,数值模拟技术可以系统地描述矿区地下水系统,评价涌水量的主要来源,并对后期矿产开采和水量的优化配置具有指导意义。How to accurately predict water gushing of mine which was studied in the text because it was the main threat for the safety of mine production. In the study, the authors built a hydrogeological conceptual model and a groundwater mathematical simulation mod- el to depict the site characteristics and groundwater system of a planning construction iron mine. Based on the simulation model, calcu- lation of water yield of the mine at - 400 m, - 500 m and - 600 m levels was simulated by means of finite-difference methods. The prediction results indicated that the numerical simulation technique could be used to describe the groundwater system of the mine, pres- ented a recognition of original gushing water, and served as guide for actual mine production and optimum distribution of water quantity.
