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 ...
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 ...
Curing conditions effect on pore structure, compressive strength and elastic modulus of cementitious tailings backfills
(Elsevier, 2023)
As a widespread application in underground metal mines, cementitious tailings backfill (CTB) has a significant implication for recycling dangerous process tailings and enhancing the safety of mining voids. The pore structure ...
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 ...
Editorial for special issue on frontiers and advances in cemented paste backfill
(Springer, 2023)

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 ...
Goaf instability in an open pit iron mine triggered by dynamics disturbance: a large-scale similar simulation
(Taylor & Francis Ltd., 2023)
The stability of concealed goafs in open-pit mines under the influence of blasting disturbances is directly related to successful mining production. Based on large-scale similar simulations, this study steadily analyses ...
Predicting long-term impact of cementitious mine fill considering sand as a copper-tailings substitution
(Elsevier, 2023)
It is of great importance to use different materials or techniques to enhance the quality/behavior of cementitious mine fill (CMF). This leads the mining industry to evaluate new production techniques or resources that ...
Identifcation of goaf instability under blasting disturbance using microseismic monitoring technology
(Springer, 2023)
Micro-seismic (MS) technique can be used to appreciate rock failure process and severity of damage by quantifying micro-earthquakes in terms of time, location, grade, and energy release. Based on 3D laser detection and ...
