| 摘 要： | 突变理论能比较有效地解决光滑系统中可能出现的突变问题.本文利用突变理论对煤与瓦斯延期突出进行了研究,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作用(爆破等)等的共同作用所产生的,并依此提出了延期突出的预测预报方法.

| Abstract: | Catastrophe theory can effectively solve catastrophe problem that can possible appear in continuum system. The mechanism of coal and gas delay outburst is studied with catastrophe theory. It is concluded that the delay time of coal and gas delay outburst is produced by the combination of geostresses gas inside coal, physics-mechanics characters of coal and external action (explosion). According to the above research, the way of preventing coal and gas delay outburst is presented. |
