【摘要】 本文以分析突水蔓延非恒定流规律为基础，将突水点的非恒定流过程分段简化为恒定流，建立突水蔓延模型，利用数值模拟技术解算突水蔓延过程；利用参数化建模技术进行巷道建模，提出高效的步行漫游方案；综合数值模拟结果和矿井场景模型，详细研究了基于物理的突水水体仿真技术，提出了一种综合的水体动态模拟方法，并基于GPU体积密度场的划分和计算方法，改进了MC（MarchingCubes）和光滑粒子流体动力学SPH（Smoothed Particle Hydrodynamics）算法；同时基于表面纹理和基于粒子系统完成了突水的真实感表达。综合应用改进的A*算法和基于导航网格的算法，输出了突水蔓延过程矿井人员最佳避灾路线，基于导航网格和Multi-agent构建了应急疏散系统。本文首次将OSG（OpenScene Graph）技术应用到了矿井突水研究中，建立了突水应急仿真软件系统，并在平朔公司井工三矿上成功的进行了实例化应用。研究成果为矿井水灾防治、事故应急救灾、事故调查、矿井人员安全教育及培训等提供一种新的技术手段。更多还原

【Abstract】 Based on the analyzing the non-constant flow law of water inrush, water inrushmodel was established through simplifying the process of water inrush point fromnon-constant flow to constant flow, using numerical simulation technology to solvethe spreading process of water, parametric modeling techniques was used to solvethe laneway model, efficient walking roaming program was proposed. Combined thecomprehensive numerical simulation results and mine scene model, inrush waterbody simulation technology was studied based on physics, a detailed study ofcomprehensive water body dynamic simulation method was proposed. GPU-basedmethod was proposed to improve the algorithms of MC（MarchingCubes） and SPH（Smoothed Particle Hydrodynamics）, Based on both surface texture andparticle-based to achieve the true expression of inrush water, with the compositeresult of A*algorithm and navigation mesh-based algorithm, best escape routes ofmine workers during the inrush water spreading process, In this paper the OSG(Open Scene Graph) technology was first applied to mine water inrush studies, asudden emergency water simulation software system was established, and ainstantiated applications was successfully completed in the three underground minesPINGSHUO company. The research results provide a new technique for mine floodprevention, emergency rescue, accident investigation, mine personnel safetyeducation and training.更多还原
