提出了煤矿工程地质模型的概念和基本构成，论述了工程地质模型及其组成单元的采动效应，建立了预测模型并成功应用于山东省横河煤矿厚松散含水层下放顶煤开采防水煤岩柱的留设，为进一步发展防水煤岩柱工程地质系统研究方法奠定了基础。

本文应用工程可靠度理论，推导出考虑指标变异性时开采覆岩破坏带高度的概率表达式，初步用实例验证了其可信性后，将其应用于金乡矿区北区覆岩破坏高度的预测。

Based on the concept of engineering geological model (EGM) and the techniques of visualization in scientific computing (VISC), combined with the project of engineering geological research on establishing the upper mining level under thick unconsolidated aquifers of Taiping coalmine, an engineering geological model has been improved in its function of visualization. The extract of modeling factors influencing on establishing the upper mining level and the methods describing the 3D features and their visualization were realized. Further more, the development of caving zone and water flowing fractured zone is predicted and simulated dynamically in order to realize the direct discovery of mining effects.
