摘　　要：本文首先收集并综合华北平原的区域地质纲要资料,其次对邢台地区显德汪矿区古构造应力场进行了分析,确定了历次构造运动对本矿区构造产生的影响,基于构造应力演化规律,通过建立了矿区的三维数字地质构造模型,结合岩石力学,弹塑性力学,断裂力学,进行数值计算。通过理论分析、数值模拟以及现场实验相结合,预测了该井田小构造分布区域和分布规律。得到矿区的断层分布区域图。该研究结果可为矿田现在采区及未开采区采掘设计提供最优方案,最大限度避免经济损失,也可为瓦斯地质分布、奥灰水赋存提供帮助。The paper collected and synthesized the regional geological outline information of the North China Plain ,and analyzed the paleotectonic stress field of Xiandewang Coal Mine area in Xingtai ,determined the effects on the mine structure produced by the previous tectonic movement .Based on the evolution of tectonic stress ,combined with rock mechanics ,elastic‐plastic mechanics and fracture mechanics to proceeded the numerical calculation ,established a three‐dimensional digital geological structure model of the mine . Through theoretical analysis ,numerical simulation and field experiments ,predicted the small structures distribution area and the distribution law of the mine field ,got the mine fault distribution area map .Not only the research results can provide the optimal mining design solution for the mining area and no mining area , but also help for the gas geology distribution and the Ordovician limestone water occurrence .
