运用新近开发的岩石破坏过程分析RFPA2D (RockFailureProcessAnalysis)系统 ,以含瓦斯煤岩的破坏过程分析为例 ,通过对含瓦斯煤岩突出孕育机制及其声发射的数值模拟 ,说明了数值模拟方法给含瓦斯煤岩突出机制及其预测理论的发展所带来的新契机 .数值模拟再现了含瓦斯煤岩突出的发生、发展过程 ,模拟结果表明 ,复杂的瓦斯煤岩断裂、突出现象可能是一些简单机理的演化结果 . Using the newly developed Rock Failure Process Analysis (RFPA2D) system, taking the destructive process of gas-bearing coal as an example, numerical simulation of the mechanism of the gas-bearing coal-rock formation and its acoustic emission is described. The new opportunity brought by the salient mechanism of gas coal and the development of its predictive theory is shown in numerical simulation.The occurrence and development process of gas-containing coal and rock are reproduced by numerical simulation. The simulation results show that the rupture of gas and coal in complex gas may be some simple The evolution of the mechanism results.
