Abstract

Taking the treatment project of tailings cemented filling for mined-out open pits in typical metal mines as background, using theoretical analysis and numerical simulation research method, the cement-sand ratio and concentration of filling slurry, the total filling height, level height, stratification height and the methods to determine the structure parameter of cement-sand ratio at different stages were provided. And then through the calculation and analysis, it is concluded that the cement-sand ratios of filling slurry of mined-out open pits are classified into three different grades: 1:8, 1:10, 1:20; the slurry concentration is 70%; the filling height is 80m; the level height is 20m; the stratification height is 1.5m; the cement-sand ratios of filling slurry of four stages are 1:8, 1:8, 1:10, 1:20.
