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 ...
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 ...
