Strength Increasing Of Ultrafine Unsized Tailing Back-filling Materials

摘要

This paper adopts physical experiment method to design uniform experiment on the basis of ultrafine unsized tailing in allusion to the problem of ultrafine unsized tailing back-filling. In this paper, the relationship between the strength of filling material and the ingredients-concentration-ratio of ultrafine unsized tailing backfilling materials is analyzed. The principle of mechanical property & it's change of ultrafine unsized tailing back-filling materials is reveal.
