The slope treatment methods of open pit dumps can be considered by cutting the slope, pressing the foot, replacing base filling, changing the discharge method, and slope reinforcement. Based on the quantitative analysis of safety factors, this paper compares and analyzes various methods of slope treatment in the dump. In practical engineering practice, the dual thought of technical feasibility and economic rationality is used to evaluate the stability coefficient of slope comprehensively. In this paper, several slope control methods used in open pit dumps are reviewed, the applicable conditions of slope treatment methods are obtained, and the results are compared and commented on.
