| Abstract: |
| In order to make the stable of open-pit to underground mining process at Xingshan iron, the orebody at -30m level should be mined and the southwest slope stability is very important to orebody mining at -30m level. So, based on the complex geological conditions and open-pit to underground mining of Xingshan iron mine, the deformation law of southwest slope is analyzed. Grey system theory is used to construct predicted model-GM (1,1) of Xingshan iron mine on the basis of its deformation law. The monitoring data are analyzed using the GM (1,1) model, and the results by model are compared with monitoring data. By the comparative analysis, the changed tredency analyzed by GM (1,1) model is consistent to monitoring results, and it is said that GM (1,1) is reliable to predict the slope deformation. |
