- W2391877894 abstract "A new type of cementing material was developed by using tailings consolidation powder(referred to as tailings powder). In order to analyze and evaluate feasibility and cost efficiency of tailings powder instead of cement being used in the underground cut-and-fill mining method with cemented total-tailings from iron mine,some relevant in-situ tests were carried out to measure uniaxial compressive strength of total tailings backfill prepared with tailings powder of different proportions and concentrations. Then use of three materials including tailings powder,cement and glue powder in backfill was compared and analyzed. Results show that tailings powder as cementing material is characterized by high strength,low cost and cost efficiency. If substituting cement in the cut-and-fill mining method,it can not only greatly reduce the cost but also realize backfilling with total tailings from iron mine,which can lay the foundation for cut-and-fill mining method being applied into lean iron deposit." @default.
