煤与瓦斯突出过程的突变分析

Catastrophe analysis of coal and gas outburst process

为了揭示出煤与瓦斯突出的机理,运用非线性理论的重要分支—突变学理论对煤矿煤与瓦斯突出的机理和突出条件进行了定性分析。考察了有可能发生煤与瓦斯突出的煤岩系统的内在动力特征, 通过建立煤与瓦斯突出的尖点突变模型,较为直观的对突出的孕育和突出过程做出了系统理论分析, 得出了瓦斯突出起动的突变机制和条件,从而为煤与瓦斯突出灾害预测与防止提供了新的理论依据。

By applying the catastrophe theory, the important branch of the essential theory of non-linear science, analyzed the inherence dynamic force character of the system that would probably occur coal and gas outburst. Catastrophe mechanism and condition of coal and gas outburst, which is the serious disaster in the produce of coal exploitation, are qualitative analyzed. The systemic and theoretical analysis of the gestation and outburst process of coal and gas outburst on an intuitive basis by setting up the cusp catastrophe model of coal and gas outburst results in the mechanism and qualification of gas outburst and brings forward a new theoretical basis for the forecast and avoidance of coal and gas outburst.
