为了研究煤矿瓦斯爆炸的特性，在理论分析和实验研究的基础上，通过引入基元化学反应，模拟了瓦斯爆炸的点火和传播特性，并对探测火焰在阻隔管内的传播特性和模拟特性进行了研究。特别介绍了17组分58步化学反应模型。仿真结果与理论分析和实验研究相吻合。为瓦斯爆炸事故调查、现场勘查和事故现场重建提供有效的依据。
In order to study the characteristics of gas explosion in coal mine, on the basis of theoretical analysis and experimental research, the ignition and propagation characteristics of gas explosion is simulated by the introduction of elementary chemical reaction .This essay is also on the research of the transmission and simulation characteristics of exploration flame in an barrier tube. Especially the 17- component, 58-step chemical reaction modeling is introduced. The results of simulation match with theoretical analysis and experimental research. In order to provide effective argument for the investigation of gas explosion, field exploration and the reconstruction of the accident.
