| Abstract: |
| A certain mine calls for a cement-flyash-tailing filling material with a compression strength of 2MPa and for a lower filling cost.According for this call,the cemented filling with the optimal proportion of raw materials is founded through a lot of tests.At the same time,the linear regression equation for the backfilling with optimal proportion is got with the method of linear regression.Also,the characteristics of the backfilling with the optimal proportion are studied.The results show that the cemented filling with the optimal proportion of raw materials not only meets the requirement of compression strength but also has the advantages of low water-decantation ratio,low density and non-separated filling slurry. |
