The analysis model of coal pillar of a empty mine goaf in north of Shanxi province was constructed and the process of coal pillar from formation to weathering was simulated through the application of software of FLAC3D in this article. The stressstrain and the law of plasticity transformation of coal pillar from formation to weathering were analyzed and the long-term stability of coal pillar was forecasted. The result showed that the stability of coal pillar was bad for excessive excavated and weathering and the coal pillar will be broken easier for pressure and shear.
