摘　　要： 运用岩石破裂与失稳过程分析RFPA2D系统 ,以含层理弱层边坡的渐进破裂与失稳分析为例 ,通过对边坡渐进破裂与失稳发生孕育机制及其锚固控制规律的数值模拟 ,数值模拟再现了含层理弱层和锚固边坡渐进破坏与失稳的发生、发展过程。模拟结果表明 。 With a newly developed numerical process, Rock Failure Process Analysis (RFPA 2D ), some numerical simulations of brittle coal and rock failure, including coal or rock containing gas, have been done to demonstrate the possibility to adopt numerical method for the coal strata movement, AE behavior and outburst mechanism of coal or rock containing gas. It is shown that the RFPA method is very promising to be used as tool to study the outburst mechanism of coal or rock containing gas.
