Abstract :
In order to study the three dimensional stability of one large underground stope after excavation, the numerical simulation software FLAC3D is used to calculate the deformation and failure situation of the surrounding rock mass. The calculations are done for two cases of whether penetration taking place in the goaf. During calculation the effects of penetration of excavation areas to the stability of stope are analyzed. The results can give some guidance for the real practice.
