摘　　要：安徽李楼铁矿地质、水文地质研究程度较低,随着生产规模扩大,给安全生产带来隐患,所以需进一步查明该矿区的水文地质条件,预测该矿区的矿坑涌水量,为矿山建设提供科学依据。本文通过分析矿区水文地质条件,研究矿床充水水源、充水通道以及影响充水强度的各种因素;依据有限差分法,利用Modflow数值模拟软件建立了地下水数值模型,并运用该模型预测了-200m深度开采的矿坑涌水量。预测结果合理,可以做为矿山开发规划的依据,并对该矿山防、治水措施提出了建议。Because the hydrogeology of Lilou iron ore in Anhui province is poor,the safety production of mine will be influenced.Studying the characteristics of the groundwater system of the mine area and forecasting mine discharge is very important for the mine production development.This paper researches the reasons of deposits of water-filled,water-filled channel and the impact of water-filled intensity of the various factors,based on the finite difference method,uses the numerical simulation software of modflow to establish numerical model of groundwater system and calculates the mine discharge of-200 meter mining in mine area.The result of prediction is reasonable and can be used to the basis for mine development planning.At last,the author makes some suggestions for preventing and controlling water.
