摘要
本文在煤和瓦斯突出固流耦合失稳理论数学模型基础上,利用固流耦合有限元程序,采用数值模拟试验的方法,分析了应力、瓦斯压力对突出发生情况的影响。数值模拟的结果将为防治突出提供数值依据。
In this paper, the authors make use of the FEM and FEMP of solid and liquid coupling which is formed according to the mathematical model of coal and gas bursts set up by solid—liquid coupling instable theory to analyze the effect of stress and gas pressure on coal and gas bursts by numerical simulation, The results will provide numerical basis for the forecast and prevention of coal and gas bursts in work—site.
