| 摘 要： | 利用非线性理论－－突变理论，对煤与瓦斯延期突出机理进行了研究，认为延期突出的滞后时间是由地应力、煤体中的瓦斯、煤的物理力学特性及外力作用（爆破）等的共同作用所产生的，并依此提出延期突出的预测预报方法。

| Abstract: | The menace of delay outburst of coal and gas is very serious. The mechanism of delay outburst of coal and gas is studied with nonlinear theory, catastrophe theory, and some useful conclusions are drawn. It is concluded that the delay time of coal and gas delay outburst is obtained by the combination of geostresses, gas inside the coal, physico-mechanical characteristics of coal and external action, e.g. explosion. According to above research, the way to predict delay outburst of coal and gas is discussed. |
