| Abstract: |
| The tailing of potash is the biggest contamination in potash mines. Stacking the waste for a long time poses a potential threat to the environment. Filling the gob with potash tailing can not only solve the environmental problems of stacking the potash tailing, but also improve the recovery of potash and the safety of mining. This paper use the condensing effect between magnesium cement and potash tailing. The stress variation and wall rock deformation caused by filling body of different proportions are simulated by FLAC3D.The numerical simulation result can be reference by similar mines. |
