Influence of types and contents of nano cellulose materials as reinforcement on stability performance of cementitious tailings backfill
(Elsevier, 2022)
This study explores the quality of cemented tailings backfill (CTB) reinforced with diverse nano cellulose materials (NCMs) such as micro-fibrillated cellulose (MFC), hydroxylated cellulose nanofiber (CNF), and cellulose ...
Reinforcement effect of polypropylene fiber on dynamic properties of cemented tailings backfill under SHPB impact loading
(Elsevier, 2021)
Dynamic loads such as blasting may lead to diverse levels of failure in cemented tailings backfill (CTB) under diverse strain rates and frequency spectral amplitudes. Hence, changes in dynamic properties of filling due to ...
Bending behavior and failure mode of cemented tailings backfill composites incorporating different fibers for sustainable construction
(Elsevier, 2021)
Mechanical characteristics of cementitious materials with fiber reinforcement are different from non reinforced cementitious materials. The influence of fiber type and content, solid content, and cement to-tailings ratio ...
Assessment of rheological and sedimentation characteristics of fresh cemented tailings backfill slurry
(Taylor & Francis Ltd, 2020)
Unreasonable choice of solid content (SC) and cement-to-tailings ratio (c/t), including pipeline networking system, will lead to some pipeline problems, such as blockage, wear, and rupture. Hence, this study deals with the ...
Strength development and microstructure characteristics of artificial concrete pillar considering fiber type and content effects
(Elsevier Sci Ltd, 2020)
The artificial concrete pillar (ACP) replacement technique is a safe and reliable method to safely mine orebody pillar in room and pillar mining. in contrast to traditional ore pillar, artificial pillar has recently received ...
Fiber length effect on strength properties of polypropylene fiber reinforced cemented tailings backfill specimens with different sizes
(Elsevier Sci Ltd, 2020)
The strength properties of cemented tailings backfill (CTB: an engineered mix of processing tailings, hydraulic binder and mixing water) is strongly affected by its structural integrity. However, our understanding of the ...
Microstructure and mechanical behavior of cemented gold/tungsten mine tailings-crushed rock backfill: Effects of rock gradation and content
(Elsevier, 2023)
Without appropriate and responsible waste management in place, the cursory storage of tailings and waste rocks on the surface can cause devastating damage to the planet's ecosystems. To proactively manage or abolish the ...

Effect of layer thickness on the flexural property and microstructure of 3D-printed rhomboid polymer-reinforced cemented tailing composites
(Springer, 2023)
For mines with poor ore bodies and surrounding rocks, the general mining method does not allow the ore to be extracted from underground safely and efficiently. For these mines, the downward layered filling mining technique ...
Mechanical, energy evolution, damage and microstructural behavior of cemented tailings-rock fill considering rock content and size effects
(Elsevier, 2024)
Cemented tailings-rock fill (CTRF) is crucial for engineering intention and durability of re-filled stopes in deep underground mines. The current work examined the effects of fragment contents and sizes on the mechanical, ...
