| Abstract: |
| Through the laboratory study of the granula grade distribution in mill tailings of Jiaojia gold mine,this paper analyzes the relationship of content ratio of classified demarcation tailings with jointing material and the fluidity of fill material,the relationship of the accumulation ratio of mill tailings and the content of overfall tailings,the relationship of maximum accumulation rate and the filling pulp fluidity,and the relationship of fill material granula grade ratio and the strength of filled-body.Wi... |
