基于元胞自动机的地下矿火灾蔓延仿真方法

提出了基于元胞自动机模型的地下矿火灾发生时火灾在巷道网络系统中蔓延的可视化仿真方法。在该方法中,用元胞自动机模型描述地下矿巷道网络系统,用元胞来描述火焰蔓延能量单元,该单元用火焰温度、蔓延速度、烟雾浓度和有毒气体浓度等状态参数来描述。在仿真过程中,可以获得大量关于火灾蔓延、灾害动态、灾害严重程度及其可行的调控方法。该方法将时间、空间和系统行为有机地结合起来,在形象、直观、真实的条件下完成火灾在巷道系统中蔓延的仿真。

New Method of Computer Simulation on Fire Spreading Along Underground Tunnels System Based on Cellular Automata

A visualized simulation on fire spreading along tunnels in an underground tunnel network system when a fire happens based on the cellular automata model was put forward.In the simulation model,the cellular automata model is applied to describe the tunnels system,and a cellular is used to represent an energy unit of flame,which is eradiated from the fire-point and contains such status parameters as temperature,velocity,smog density,density of poisonous gases.In simulating process,a great deal of information about fire spreading,destruction dynamics,degree of casualty and feasible measurements of adjustment and control is obtained.In the method,time,space and behaviors of system are linked together,thus a more authentic and visualized simulation on fire spreading along tunnels is made.
