摘　　要：我国煤炭地下开采占全部产量的 96 % ,含瓦斯煤层多 ,高瓦斯矿井和突出矿井占矿井总数的4 4 % ,由瓦斯引发的爆炸事故的伤亡人数占全部矿井事故伤亡总数的 6 5 %。针对我国煤矿安全生产的严峻形势 ,笔者在对瓦斯爆炸事故特性进行分析的基础上 ,应用混沌理论对瓦斯爆炸事故的风险以及控制方法进行初步探讨 ,初步建立了瓦斯爆炸事故混沌特性分析模型 ,对预防和控制瓦斯爆炸事故的发生 ,改善矿井安全生产状况具有指导意义。In China, 96% of the total coal output is from underground pits enriched with gas seams. Among them 44% of the total mines are rich in gas or gas outburst mines. 65% of the total casualties are caused by gas explosion accidents. Aiming at the severe situation of the production safety, and based on the characteristic analysis of the gas explosion accidents, preliminary exploration in the risk of gas explosion accidents and their control measures is conducted by applying the chaotic theory. An analytical model for chaotic features of the gas explosion has been established. It is of great significance in preventing and controlling the gas explosion accidents, so as to improve the safety situation in coal production.
