Abstract: Based on three-dimensional geological model which has been established in an open-pit mine to the realm different from the traditional optimization methods，the use of current domestic outstanding open-pit mining software 3Dmine realm of optimization，a true sense of the final state had been achieved.Explained by using mining software to optimize the complete process line state and in the final state on the basis of the formation of the open-pit design，the modeling results were analyzed.

Key words: 3DMine, State optimization, Open-pit mining
