| Abstract: |
| In order to study the application of graded tailing in mine filling, the physical and chemical properties and particle composition of graded tailing are analyzed. The results show that the slurry has better flow characteristics when the ratio of ash to sand is 1:4 ~ 1:8 and the concentration of slurry is 68% ~ 72% , pumpability and filling uniaxial compressive strength. It is demonstrated that the tailings can be used for mine filling, which improves the production capacity of mine filling and solid waste disposal capacity, effectively solves the problem of mining filling balance, and provides reference for similar mines. |
