摘　　要：针对露天开采的特点,提出了一种露天矿地形地质集成实体模型快速动态更新方法。该方法对地形及采场模型采用扩展边界内局部更新方法,实现采动范围内新旧两期DEM无缝拼接;地质模型则采用重构方法,将新增的写实数据作为新的样本点,重新进行空间插值,重构地层及地质体模型;更新后的地形、地质实体模型,通过两两布尔运算进行实体耦合,实现了地形地质集成实体模型的动态更新。应用实例表明:该方法快速可靠稳定,操作性强,能够实现工程体无缝开挖模拟和空间分析,满足了生产设计及工程管理对于地形地质集成模型动态精准的要求。According to features of a surface mining, a rapid dynamic upgraded method of a surface mine topography and geologic integrated entity model was provided. With a local upgraded method within the expansion boundary, the method could realize a seamless splicing between the new and old DEM in the mining scope of the topography and mining block model. With a reconstruction method, the geological model could make new written data as a new sample point, a space interpolation could be re - conducted and the strata and geological model could be reconstructed. The topography and geologic entity model upgraded would realize the dynamic upgrading of the topography and geology integrated entity model with the Boolean calculation conducted on the solid coupling. The application cases showed that the method was rapid, reliable and stable with a high operation, could make a seamless exaction simulation and space analysis on the engineering mass and could meet the dynamic accurate requirements of the production design and engineering management to the topography and geology integrated entity model.
