| Abstract: | The methods combined by test, field monitoring and theoretical analysis were adopted to do the systemic research on the rock mass from micro structure to macro deformation, and rheological model of Jinchuan rock mass was established to discuss the reasonable supporting time. Results show that supporting after suitable stress and displacement release can benefit for the long term stability of surrounding rock. |
| Keywords: | complex geological conditions surrounding rock characteristic test supporting time theological characteristic |
