The optimization design of mi ning boundary, the stability analysis of the slope and the choice of m ode of transportation are it’s indispensable links . In order to realize the benefit maximization of mini ng enterprises, this research will carry out optimization research about the mining boundary and mining waste rock emission reasonable plan, of a large open-pit mine in our country. The new technical methods of the mini ng boundary optimization and reasonable transportation plan of waste rock are given in the study. In the optimization analysis, the mining boundary is optimized by dynamic program ming and the slope stab ility is calculated by the Sweden
