  • Pre-stressing cable has rarely been used in supporting mining slopes even though it has been widely applied in geotechnical slope projects. This paper presents an engineering example for the application of pre-stressing cable in supporting excavated slope in the west open-pit of the Pingzhuang coalmine. Slope stability analyses are conducted under different geological conditions and supporting parameters. The results indicate that the stability of the slope is increased with the pre-stressed cable, and reinforcing parameters satisfy the requirements for safe operations. The technique has been adopted to enhance the slope stability in the mine.
