摘　　要：奥陶系灰岩构造、岩溶发育,对许多井田安全开采构成严重威胁。利用放水试验及数值模拟方法可以有效地查明该含水层主要水文地质特征。运用区域分解法的基本思想对某井田放水试验进行数值模拟。根据井田内的主要构造分布及性质,选择界面上通量一致的条件将原问题分解为各子域问题,各子域内采用有限单元法求解。模拟结果显示区域分解算法可以有效的应用于矿区含水层地下水运动的数值模拟。For Ordovician limestone structure and karst growth, they seriously endanger the safety mining of many mine fields. The outflow test and numerical simulation method can find out the main hydro - geological character of the aquifer effectively. In the paper, the numerical simulation on certain mine field was carried on which is based on the idea of domain decomposition method. According to distribution and property of main structure, it chooses the continuous conditions of flux in the interface to divide the original problem into subdomain problems. In each sub - domain, the problem is solved by the finite element method. The result shows that the domain decomposition method is effective to apply on the simulation of groundwater flow in mine area＇ s aquifer.
