瓦斯爆炸事故作为矿井灾害系统中一个重要的子系统,其演变过程中的一些特征表明,它与混沌现象有着密切的关系,因此在对矿井工作面瓦斯涌出时间序列观测数据分析的基础上,应用混沌理论中的自相关函数、相空间重构、Poincare截面和返回映象等对该工作面瓦斯涌出进行了混沌特性研究和判别,初步证明了该工作面瓦斯涌出具有混沌特性,同时,对瓦斯爆炸演变系统进行综合分析发现,瓦斯爆炸的演变过程存在明显的蝴蝶效应.
Gas explosion accident is an important subsystem in the mine disaster system,and some characteristics is showed that it concerns chaos phenomena very nearly in its evolvement process.Therefore,after analyzing the coupling characteristics of the gas gush system of the excavation working faces and the chaotic theory,the chaotic characteristics of the gas gush in the working faces were determined by applying the autocorrelation function,the phase reconstruction,the Poincare section and the power spectrum of th...
