Analysis of strength and microstructural characteristics of mine backfills containing fly ash and desulfurized gypsum
(MDPI, 2021)
The utilization of solid wastes (SWs) as a potential resource for backfilling is not only conducive to environmental protection but also reduces the surface storage of waste. Two types of SWs, including fly ash (FA) and ...
Analysis of tensile mechanical characteristics of fibre reinforced backfill through splitting tensile and three-point bending tests
(Taylor & Francis Ltd., 2021)
The cut-and-fill mining method is used in metalliferous mines thanks to backfilling instead of ore pillars. However, the stability of the artificial cemented tailings backfill (CTB) roof is one of the key influencing factors ...
