CHINA MINE ENGINEERING

In this article, tests are conducted to obtain the physical properties, chemical properties, size composition and basic properties of the full-tailings of a certain mine, and also conducted for the full-tailings settleability test, uniaxial compressive strength test and rheological behavior test. The test results show that when the cement-sand ratio of the tailings backfilling slurry is 1〖DK〗∶4~1〖DK〗∶6 and the slurry concentration is 68%~72%, the fill mass has good uniaxial compressive strength and flowing property. The optimal parameters for design of mine backfilling with mineral processing tailings are elaborated. The production capacity with mine backfilling method and the solid wastes disposal capacity can be improved, which can provide a reference for backfilling design of similar mines.
