A combined experimental and numerical study on the triaxial and dynamic compression behavior of cemented tailings backfill
(Elsevier Sci Ltd, 2020)
A full understanding of the mechanical response of cemented tailings backfill (CTB) under various loading scenarios is beneficial for mining engineering applications. This study experimentally investigates the stress - - ...
Characterization of early age behavior of cemented paste backfill through the magnitude and frequency spectrum of ultrasonic P-wave
(Elsevier Sci Ltd, 2020)
Cemented paste backfill (CPB) is broadly used for underground backfilling, improving the mechanical performance through the modification of its composition and, therefore, its microstructure and characteristics. in order ...
Effect of mineral admixtures on flow properties of fresh cemented paste backfill: Assessment of time dependency and thixotropy
(Elsevier, 2020)
Cemented paste backfill (CPB), an engineered mix consisting typically of tailings, cement and water, has become a regularly used structural material in most mines worldwide. the performance of the CPB structure is dependent ...
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 ...
Exploring the link between ultrasonic and strength behavior of cementitious mine backfill by considering pore structure
(Elsevier, 2023)
Understanding the porosity/pore linkage and strength properties of cementitious mine backfill (CMB) is essential for the design of underground mining filling. Adoption of new production techniques in parallel with the ...
Study of early-age performance of cementitious backfills with alkali activated slag under internal sulfate attack
(Elsevier, 2023)
The vulnerability to internal sulfate attack of calcium-rich ordinary Portland cement (OPC) and its relative high cost force mines to explore technically effective and low cost alternative binders to solidify sulfate-containing ...
Performance based assessment of a small-scale artificially nourished beach
(Elsevier, 2023)
In coastal engineering studies, coastal protection procedures can be provided by hard and soft methods. Soft methods applied using the right techniques and methods are not only long-lasting but also adapt to the natural ...
Progress and prospects of mining with backfill in metal mines in China
(Springer, 2023)
Mining is the foundation of modern industrial development. In the context of the "carbon peaking and carbon neutrality" era, countries have put forward the development strategy of "adhering to the harmonious coexistence ...
Long-term ageing characteristics of cemented paste backfill: Usability of sand as a partial substitute of hazardous tailings
(Elsevier, 2023)
Considering environmental problems caused by sulfidic tailings as a result of long-term ageing as well as inadequacies in their gradations in ensuring the strength needed for cemented paste backfill (CPB), there is a need ...
