摘　　要：数字矿山是21世纪新技术条件下信息化与智能化的产物,建立矿山三维地质体建模是实现数字矿山的基础与核心.为了实现复杂矿山三维地质建模的经济性、真实性和有效性,如何对离散的DEM空间数据进行前期处理,是建立逼真的矿山三维地质模型难点与前提.针对不同矿山与地貌环境条件下,采用几种基本空间插值法对离散的DEM空间数据进行插值,然后对其插值后的数据进行质量评定与交叉验证,确定最优化的空间插值方法.分析结果表明不同的空间插值方法适应不同的地矿环境领域,对离散的DEM空间数据进行最优化的空间插值,是实现逼真的矿山三维地质体建模这一目最有效最核心的方法.Digital mine is an informational and intelligent product which appears in the 21st century un-der the new technology.Building mine 3D geological modeling as the foundation and core is to realize dig-ital mine.In order to achieve the complex mining character of 3D geological modeling-economics,authen-ticity and effectiveness, how to pre-process the discrete DEM spatial data is the difficult point and pre-condition for building realistic mine 3D geological modeling, the article describe that according to the dif-ferent mine and geomorphic environment conditions,several basic spatial interpolation methods are used to interpolate the discrete DEM spatial data and then the interpolated data is conducted by the quality evalu-ation and cross-validation to determine which the optimal spatial interpolation methods is beast.Analysis results indicate that different l spatial interpolation methods adapt to different geological mining fields, and the DEM spatial data of discrete optimization of spatial interpolation become most effective and central method to accomplish the project of mining 3D geological modeling realistically.
