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 sedimenta-tion test ,saturation concentration test and bleeding test are carried out to obtain the basic characteristics of filling tail-ings.Based on the results and those of the strength and slurry diffusance tests ,the delivery concentration of slurry is recognised 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 .
