摘　　要：为真实再现矿井火灾发展的变化及时空影响,探讨了矿井火灾的场量建模技术与其可视化仿真。基于矿山复合场的内涵,提出了面向矿井火灾的场量表达。经矿井火灾场量的空间几何特性、属性分布特性、运行状态特性、矢量方向特性及时序特性的建模分析,给出了适用于火灾场量的一体化模型结构,进而建立了分别用于描述井巷工程、通风网路及火灾烟流的空间几何场量模型、物理属性场量模型及气象参数场量模型。通过生成火灾场量的模型类与时序流程,实现了矿井火灾场烟流发展变化的三维可视化仿真。最后结合国内某矿山实际,验证了矿井火灾场量模型的可行性。In order to real reproduce the development,changes and spatio-temporal effects of underground fire,investigated the field variables modeling and visualization simulation of fire disaster in underground mine. Based on the connotation of the mine complex field,the field variables expression of fire disaster was proposed. The field variables properties include the space geometry,the distribution of the properties,the running status,the vector direction as well as the time sequence. With the field variables modeling and analyzing of fire disaster,a field parameter model which was applicable to fire disaster field variables was established. Furthermore,the field variables model of space geometric properties,the field variables model of physical properties as well as the field variables model of meteorological parameters were established to describe underground engineering,ventilation network as well as fume flow of fire respectively. The field variables model class and time sequence flow sheet of fire disaster were generated,the three-dimensional visual simulations for the fume flow developments and changes of the fire field in underground mine is realized. Finally,according to the states of a Chinese mine,the feasibility of the field variables model of fire disaster in underground mine was verified.
