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 ...

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 ...
Gamma ray and neutron shielding properties of some concrete materials
(Elsevier, 2011)
Shielding of gamma-rays and neutrons by 12 concrete samples with and without mineral additives has been studied. The total mass attenuation and linear attenuation coefficients, half-value thicknesses, effective atomic ...
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, ...
