摘　　要：为有效指导地下矿火灾救避灾方案的制定与实施,探讨火灾烟流蔓延过程的三维仿真模型构建技术非常必要。为此提出了以井巷空间三维结构模型构建为载体、以通风系统三维网络模型构建为保障、以烟流蔓延参数模型构建为核心的烟流蔓延三维仿真模型构建技术。通过以时间为序、采用体绘制技术对构建的烟流蔓延三维仿真模型进行了可视化实现,主要模拟了烟流在三维井巷中的动态蔓延过程,进而揭示了烟流温度、浓度等在时间、空间上的发展变化。并以国内某矿山为例,检验了烟流蔓延三维仿真构模技术的有效性。Discussion of 3 D simulation modeling techniques of fire fume spread process is very necessary to effectively guide the formulation and implementation of underground mine fire rescue and evacuation plan. Therefore,3 D simulation modeling techniques of fire fume spread were proposed, with 3 D structure model of underground mine roadways as the carrier,3 D network model of ventilation system as the guarantee, and fume spread parameters model as the core. The volume rendering technology in time sequence was used to develop the 3D simulation model of fire fume spread process ,which primarily simulated the fume dynamic change of fume temperature and concentration. Finally spread process in 3D roadways and showed time and spatial , the model was applied to a domestic mine and the simulation results indicated the model＇s effectiveness.
