| 摘 要： | 为表现煤层自燃燃烧变化的动态过程,引入元胞自动机(Cellular Automata)理论用于模拟煤火的燃烧蔓延规律。根据煤火燃烧的特点,将元胞四元组的状态进行扩展,将状态S扩展为一个函数f(s),解决了传统CA理论无法准确细致地描述空间热场的分布的限制,同时研究了燃烧学,传热学等理论,将f(s)与煤岩赋存状况等条件结合,给出尽可能符合实际的模拟函数,最终在试验区得到满意的模拟效果。

| Abstract: | The Cellular Automata(CA) theory is used to simulate the dynamic burning and spreading process of coal fire.According to the characteristic of coal fire,Cellular state S is extended into a functionf(S).It settles the limitation that traditional CA can't well describe distribution of spatial heat fields.At the same time,the theories of burning and heat transfer are studied.In combination with the surrounding states of coals and rocks,the function F(s) is up to the fact as soon as possible.At last the simulation result is satisfactory in the test area. |
