| Abstract: |
| Aim at the effect which made by the height of the stack and the discharge to the stability of the spoilbank, this paper offers a theoretically basis to the follow-up stack and discharge work for the spoilbank, which take a engineering example of the outdoor mining spoilbank of Xiaoheigou in Yunnan province, the test adopted the FLAC3D to make a numerical imitate of the nonlinear, by which the stablity condition of the spoilbank had been analysised. The result of the imitate indicated that the spoilbank would be stablely when it in a present situation or after the two staircases were added in the foundation; The total height of the stack and discharge would up to 120m when three staircases were added to the foundation, by now, the slope of the spoilbank still in a contion of a ultimate balance, and it would reach a stable state after the unloaded by a means of cutting the slope. |
