| Abstract: | The test on basic performance of filling tailings constitutes the fundamental work in the application of filling technology. In the paper,the physico-chemical properties of filling tailings are tested ,and thetailings sedimentation test, saturation concentration test and bleeding test are carried out to obtain the basic characteristics of filling railings. Based on the results and those of the strength and slurry diffusance tests, the delivery concentration of slurry is reeognised as 70 % to 72 % , and cement-sand ratio is between 1： 4 and 1 ： 8. The data are fundamental for the design of the filling process and filling system in Jinchangyu Gold Mine. |
