摘要
利用东北大学岩石破裂与失稳中心研制开发的“RFPA2D-Flow)固气耦合系统模拟含瓦斯煤岩在不同的恒定载荷、瓦斯压力作用下变形随时间发展并最终达到损伤、破坏这一流变过程,用数值模拟方法研究瓦斯渗流下的煤岩流变特性。
With loses the stead central developmen using northeast University rock breaking （RFPA 2D - Flow） the solid gas coupled system simulation to contain the light coal crag under the different constant load, the gas pressure function distorts along with the time development and finally achieved the damage, destroys this to change the process, changes the characteristic with the value simulation method research gas transfusion under coal crag.
