针对石膏矿采空区稳定性研究的紧迫性，系统介绍了国内外采空区稳定性经典理论，以及如何利用FLAC3D﹑ANSYS等软件进行静态数值模拟。论文着重从岩石流变﹑爆破扰动﹑长期强度等多因素动态演变方面对采空区稳定性进行探讨。研究讨论认为，如何将支撑采空区稳定的顶板-矿柱-底板体系中岩石受扰动、流变作用的动态演变纳入采空区稳定性分析中，建立量化多因素耦合模型和基于常应力状态的破坏准则及动态破坏机制，将成为未来研究的重点方向。

According to the urgency of stability on gypsum mine goaf ,this paper systemly intro-duces the classical theory research of domestic and foreign ,and static mumerical simulation analy-sis by using FLAC3D and ANSYS software .The dynamic evolution of stability on gypsum mine goaf respectively from rock rheological ,blasting disturbance and long-term strength is discussed . Research suggests ,that how to make dynamic evolution of rock influenced by disturbance ,rheo-logical in the roof-pillar-floor rock system w hich support goaf stability into the goaf stability anal-ysis ,establish a quantitative multi-factor coupling model ,dynamic failure criterion and dynamic failure mechanism for often stress state ,will be the key focus of the future research .
