| Abstract: |
| In order to analyze the slope stability of the Huangmeiling Open-Pit Mine, it is necessary to comprehensively understand the geological conditions of the slope and to obtain reliable and reasonable mechanical parameters of the slope rock mass. The mechanical parameters such as tensile strength, Poisson's ratio and elastic modulus of rock mass in HML mine are measured by indoor rock mechanics test. Then the measured mechanical parameters of Huangmeiling slope are processed by several rock mechanics parameters conversion methods based on the combination of indoor rock sample experiment and engineering geological data. Finally, a more reasonable and accurate rock mechanics parameter which can be used in actual engineering analysis and modeling calculation is obtained. |
