Abstract
This article systematically analyzes the geological characteristics of the slope in Xinling Open-pit Mine,and explores the application potential of prestressed anchor cable reinforcement as a slope protection measure.Based on the strict theoretical framework of mechanical balance and the consideration of economic benefits,the design parameters of prestressed anchor cable reinforcement of slope are adjusted to achieve the dual optimization objectives of structural stability and economic rationality.The results show that the slope reinforcement scheme after optimization is the upper two rows of anchor cable length of 25 m,the middle two rows of anchor cable length of 20 m,and the lower two rows of anchor cable length of 16 m.The slope stability coefficient of the reinforcement scheme can reach 1.3.The application of anchor cable has a remarkable effect on slope protection,which can effectively ensure the stability of slope protection in open-pit coal mines.关键词
