Article Synopsis
- Backfilling is an effective technique for managing surface subsidence in mined areas and disposing of mineral processing wastes, but there's a need for tougher materials to withstand complex loads.
- This study explores the use of polypropylene (PP) fibers to enhance the strength and cracking resistance of fiber-reinforced aeolian-sand backfill materials (FABs) through various tests that assess their performance under stress.
- Findings indicate that while increasing fiber volume can reduce compressive strength, the optimal amount (0.6% of PP fibers) significantly improves bending strength, with longer fibers (9 mm) better at controlling cracks and improving overall durability.
To achieve sustainable utilization of a large amount of mine solid waste, this study investigated the performance of self-compacting coal gangue-filled backfill (SCFB) containing biomass fly ash (BFA) generated from biomass power plants as a supplementary cementitious material (SCM). The correlations between the physical structure and compressive strength of SCFB samples were obtained by ultrasonic pulse velocity (UPV). The failure process of the SCFB samples was monitored by the digital image correlation (DIC) technique, and the stress-strain relationship and failure pattern were also analyzed.
