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.
From the perspective of digitization and visualization of mine engineering, the underground mine is regarded as a dynamic field containing many kinds of geometric quantities, attribute quantities, parameter quantities and state quantities, which are called underground mine complex fields. By analyzing various types of spatial fields The geometric characteristics, distribution characteristics, vector characteristics and spatio-temporal sequence characteristics of all kinds of space are given, and the characterization methods of all kinds of spatial fields and their interrelations are given, and then an integrated digital model based on voxels is proposed. Quantification, field quantification and integrated processing to form integrated model construction technology of underground mine complex field.With the actual data of a typical domestic mine as an example, the geometrical characteristics of surface topography, fault and shaft and tunnel engineering are achieved, the grade of ore , The 3D visualization simulation of vectorial characteristics of downhole ventilation system and the dynamic simulation of fire spread are carried out, and the feasibility and validity of the integrated model of underground mine complex field are verified.
