| Abstract: |
| One’s Mine is located in west of Kunlun Mountains and south of Qaidam Basin of Qinghai Province. Ore bodies, controlled by the mafic-ultramafic complex, are unanimous with rock in strike. The ore direction is northeast-east with the strike length 1680m, average thickness 85m, and average angle 20°. Mine is designed as strip mining with the final slope angle 48°in southwest. Based on three-dimensional mining project software and numerical simulation analysis software, this paper is mainly to study the slope stability, The results indicate that the lower middle part of strip mining final slope may occur rock mass failure and exist the safety loophole. This paper will provide the theoretical basis for reinforcement of strip mining slope. |
