摘　　要：山东宁阳县伏山煤矿32603回采工作面位于承压水上,根据井田煤层赋存状况与地质特点,通过对断层与地层特征的分析,建立了区域地质模型,并进行有限元模拟计算分析。研究表明,建立的区域地质模型合理,模拟计算结果可靠,为该矿井的安全生产提供了科学指导。The 32603 working face of the Fushan mine located in Ningyang county,Shandong province is above the bearing water. According to the occurrence of the coal seam and the geological characteristics, the geological models of zone were established through the analysis of the fault and the formation. Results showed that the established regional geological model is reasonable and simulation results are reliable which provided scientific guidance for the mine safety in production.

关 键 词：底板破裂厚度 地质模型 计算机模拟
