Abstract: The optimum slope design is one of the keys to maximize the economical benefit for a mine enterprise. In this paper, the systems optimum method for the slope engineering is described based on the principles of the engineering optimum and the concept of systems engineering. Incorporating the slope engineering Into the mining technology is emphasized. The systems analysis method and the systems simulative technique are utilized as a whole and the optimum numerical methods are used in the specific procedures. Finally, the slope design with maximum benefit, optimal technology, reliable safety and minimum economical risk should be recommended.
