摘要：Pipeline transportation of the backfilling material is an important part of the backfill mining method. The rheological property of the filling slurry is the cornerstone of pipe diameter selection and resistance calculation. Its research matters not only mining costs, but also the safety in production. In order to ensure the whole-tailings paste backfilling material of Shirengou iron mine can be achieved pipeline transportation, L-pipe experiment is designed in this paper to study the transport characteristics of the whole-tailings paste in the pipeline. The study results provided theoretical basis for determine the best transport concentration, cement/aggregate ratio and the pipeline self-flow transportation concentration limit.
