The method of stage filling mining is introduced in this paper. In order to control the shaft of overburden movement and protect auxiliary shaft, four ore mining plans are proposed for YOUJIANG Mining. The simulation models are established. The powerful numerical ability of ANSYS is used to the reliability of four ore mining plan. The results show that: None of the four plan cause auxiliary shaft rock failure. The first plan is minimum stress in all directions. So it is optimal mining plan. A theoretical basis is provided for actual mining.
