地下礦水災場一體化構模及可視化仿真技術

Integrated modeling and visual simulation of water inrush in an underground mine

  • 摘要: 針對地下礦突水三維可視化仿真,基于礦山復合場理論,通過對水災漫延過程中各場量參數的空間幾何性、分布性、矢量性和時序性進行分析,給出屬性空間的拓撲關系,構建了地下礦突水仿真的一體化動態模型,提出了相關屬性的可視化仿真方法.通過對空間場量進行體素化和場量化處理,以時間為步長,實現了水災漫延過程的動態可視化表達.以某典型地下礦山為例,通過對相關數據進行整理分析,實現了水災漫延過程的動態可視化仿真,驗證了地下礦突水一體化模型的可行性和有效性.

     

    Abstract: 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, distribution, 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.
