Preliminary Study on Optimization of Filling Ratio of Whole-tailing Paste in a Copper Mine

In order to achieve the goal of high-quality paste filling in a copper mine of Hubei Prov⁃
ince,aiming at the problems of low slurry concentration,large underground drainage and high filling cost,
a study on the optimization of the filling ratio of the whole-tailing paste was carried out. The test results
show that,when the cementing powder is used as the cementing material for paste filling,the cement-sand
ratio of the filling body that meets the production requirements of the mine is 1∶7,and the slurry concentra⁃
tion is greater than 68%. When P.O42.5 ordinary Portland cement is used as paste filling cementing materi⁃
al,the cement-sand ratio of the filling body that meets the production requirements of the mine is 1 : 3,
and the slurry concentration is greater than 71%.Compared with P.O42.5 ordinary Portland cement,the use
of cementing powder can save the cost of filling materials by 13.687 million yuan/a,and the economic bene⁃
fits are remarkable. The results of this study can provide a theoretical basis for the selection of binders in
the later paste filling process.
