摘要：
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. (C) 2011 Published by Elsevier Ltd.
