| 摘 要： | 为正确认识煤与瓦斯突出机理，将突出煤体视为煤与瓦斯承压散体，提出并初步研究了煤与瓦斯承压散体失控突出机理.先介绍了突出煤体视为散体的可行性，再根据牛顿第二定律导出煤与瓦斯承压散体的动量方程，结合突变理论导出煤与瓦斯承压散体运动突变势函数，并分析了承压散体失控突出机理对突出过程的描述、运动突变条件、影响煤与瓦斯突出因素，最后用现场煤样在伺服岩石力学试验机做煤样力学性能和水渗透性能实验来验证该机理的正确性.

| Abstract: | For knowing the mechanism about coal and gas outburst,put forword and firstly worked over outburst mechanism for compression disseminated values of coal and gas out of control that outburst coal is regarded as compression disseminated values of coal and gas.Firstly,introduced the feasibility of outburst coal regarded as compression disseminated values of coal and gas.Secondly,educed momentum equation of compression disseminated values of coal and gas according to the Newton second law,analyzed potential function of compression disseminated values of coal and gas movement,and the mechanism described outburst process,movement saltation condition and factor of influence on outburst.Finally,validated the accuracy of the mechanism by doing experiment of coal mechanics and water osmosis performance in the servo rock mechanics testing machine with scene coal. |
