摘　　要：大平矿水库下煤炭储量占井田工业储量的49.5%,水库下安全开采是矿井亟待解决的问题。基于ArcGIS Engine应用技术和概率积分法地表移动变形预计模型,以库区地理信息系统和开采沉陷预计系统为基础平台,采用高精度的不规则三角网建模方法建立了库区地形数字高程模型,利用回采工作面地表移动和变形预计结果提出了下沉盆地在库区地形数字高程模型中的无缝嵌入技术,实现了库区地理数据库的动态修正和库区三维地表的实时重构,通过库区地表的三维分析功能精确模拟了库水的移动和分布规律,为水库下煤炭协调开采计划优化和矿井安全开采提供了科学的决策支持。The coal reserves under reservoir accounts for 49.5% of the minefield industrial coal reserves in Daping coalmine, it is urgent to solve the problem of safety mining under reservoir. Based on the geographic information system of reservoir region and mining subsidence prediction system developed with the applied technique of ArcGIS Engine and ground movement and deformation prediction model of probability integration method, the digital elevation model of reservoir topography was established with high precision triangulated irregular network, the technique of subsidence basin seamlessly embedded in the digital elevation model of reservoir topography was put forward with the ground movement and deformation prediction result, the dynamically correcting of reservoir region geographic database and reconstructing of the three-dimensional reservoir surface in real time was realized, the movement and distribution law of reservoir water were accurately simulated with three-dimensional analysis of reservoir surface, and scientific decision-making support for the optimization of coordinated coal mining plan under reservoir and safe mining of the coalmine was provided.
