摘　　要：针对露天矿复杂的地形特征,提出无编码约束条件下的露天矿精细DEM建模方法,利用该方法在CAD软件中实现了露天矿精细DEM的建立与三维显示,验证了模型的正确性。该模型可用于露天矿采剥量计算、矿岩量分类计算、矿区三维浏览、以及矿区时空数据库的建立等。Aiming at the complicated characteristics of open pit terrain, this paper gave a method to build the Fine DEM of Open Pit with uncoded constraint condition, and validated the correctness of DEM model by its three-dimensional display in CAD software. The DEM can be used in calculating the digging volume of open pit, calculating volume of several ore rock, 3-D browse of mine area, building spatio-temporal database of mine area.
