Analysis on Nonlinear Dynamics Phenomena in Gas Calamity Process

摘要：

The complexity in gas calamity process shows the nonlinear characteristic of the system. Conventional prevention and control means by setting its change law and characteristic beforehand have showed its limitations. Aiming at the nonlinear dynamics phenomena in gas accidents, gas emission, outburst and explosion in its calamity process are analyzed and summed up by nonlinear theory. The result shows the process of gas emission takes on obvious chaos movement, the process of gas outburst takes on the catastrophe and the process of gas explosion takes on obvious butterfly effect. It is proved that the gas calamity process of mine has nonlinear characteristic. To research the gas calamity by nonlinear dynamics theory is feasible and reasonable and it is important for the holistic prevention and cure of mine safety to lucubrate the complex dynamics characteristic.
