摘　　要：从矿山工程数字化及可视化的角度,将地下矿山看作是一包含多种几何量、属性量、参数量和状态量的动态量场,称之为地下矿复合场.通过分析各类空间场量的几何特性、分布特性、矢量特性和时空顺序特性,给出了各类空间场量及其相互关系的表征方法,进而提出了基于体素的一体化数字模型.经空间场量体素化、定量化、场量化及一体化处理,形成了地下矿复合场的一体化模型构建技术.以国内某典型矿山的实际数据为例,实现了地表地形、断层和井巷工程等几何特性、矿石品位的空间分布特性、井下通风系统的矢量特性的三维可视化仿真及火灾蔓延的动态仿真,进而验证了地下矿复合场一体化模型的可行性与有效性.In terms of holistic digital modeling and three-dimensional （3D） visualization, an underground mine was treated as a dynamic field, named as the underground mine complex field, which includes various geometries, attributes, parameters, and states. By analyzing the geometric, distributive, directional, temporal and spatial characteristics of these field variables, this paper proposed a characterization method of these variables and their relations, and then built a holistie digital model of the complex field based voxeliza- tion. Specific techniques for building the holistie digital model were developed by voxelizing, quantifying, regionalizing, and integra- ting these field variables. A case study was used to implement the model and techniques. It is demonstrated that the holistic approach in the paper is effective for digital modeling and 3D visualization of the complex field, including geometric variables such as topogra- phy, faults and opennings, distributive variables such as ore grade, and directional variables such as air flows and mine fires.
