| Abstract: | The mathematical models on rockmass displacements for underground mining and slope stability are established by using fuzzy mathematics theory and applied to predict the rockmass displacements and deformations due to open-underground combined mining for the thick ore body with steep dip angle. The fuzzy mathematics method is used to determine the engineering parameters for analysis and calculation. The results of calculation can be applied to predict ground surface movements due to underground mining,and provide a theoretical basis for mining engineering design. |
