地下水模拟技术是进行煤田地下水环境影响评价和矿区疏干排水设计的主要工具。该文以宁夏甜水河煤田为研究对象，根据矿区地质条件和水文地质条件的分析，确定模型边界条件并建立了水文地质概念模型，应用基于有限差分法的MODFLOW程序，建立地下水流三维模型，进而对煤田各开采阶段的地下水流场和涌水量进行预测，从而为煤田地下水有效防治和安全生产提供依据。

Simulation technology of groundwater is the main method for evaluating the effect of coalfield groundwa-ter and designing the drainage in mining areas.According to analyzing geological conditions and hydrogeology char-acteristcs in mining areas,the conceptual model of hydrogeology is set up and the boundary conditions are deter-mined.By taking Tianshuihe coalfield in Ningxia as the research object,using finite difference MODFLOW pro-gram,a 3D numerical simulation model for the groundwater is established.It can provide more precise information for effective control of groundwater and safety exploration based on predicting the groundwater flow field during the coalfield exploitation and water inflow.
