摘　　要：针对地下矿突水三维可视化仿真,基于矿山复合场理论,通过对水灾漫延过程中各场量参数的空间几何性、分布性、矢量性和时序性进行分析,给出属性空间的拓扑关系,构建了地下矿突水仿真的一体化动态模型,提出了相关属性的可视化仿真方法.通过对空间场量进行体素化和场量化处理,以时间为步长,实现了水灾漫延过程的动态可视化表达.以某典型地下矿山为例,通过对相关数据进行整理分析,实现了水灾漫延过程的动态可视化仿真,验证了地下矿突水一体化模型的可行性和有效性.This article is aimed at the three-dimensional visual simulation of water inrush in an underground mine. The topological properties of spatial relationships were presented based on the mining complex field theory and by analyzing the space geometry, distri-bution, vector property, and time sequence of field variables during a water inrush process. An integrated dynamic simulation model of water inrush in an underground mine was built and a visual simulation method of related attributes was put forward. After the voxel and field quantification treatment of spatial field variables, the dynamic flood spreading process was expressed visually by time step. With a typical underground mine as an example and through the analysis of relevant data, the dynamic visual simulation of water inrush in this underground mine was implemented and the model’s feasibility and validity were tested and verified through this case study.
