煤与瓦斯突出启动和终止的尖点突变研究

Study on Cusp Mutation of Startup and Termination of Coal and Gas Outburst

在建立煤与瓦斯突出的安全力学条件下,运用尖点突变理论研究矿井中的煤与瓦斯突出,通过构造煤与瓦斯突出的突变势函数,利用突变尖点模型对突出的启动和终止过程进行定性分析和研究,从而为煤与瓦斯突出灾害预测与防治提供新的理论依据。

Under the condition of setting up safety mechanics of coal and gas outburst, the cusp mutation theory was applied for studying coal and gas outburst in mine production, qualitative analysis and study were conducted according to the potential function of the mutation of the structural coal and gas outburst and the startup and termination process of the outburst caused by the cups mutation model,this thus provides a new theoretical basis for the prediction and prevention of coal and gas outburst disaster.
