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 ...
Novel binder material in geopolymer mortar production: Obsidian stone powder
(Wiley, 2023)
This paper presents the results of mechanical and micro-structural properties of geopolymer mortars with obsidian, ground granulated blast furnace slag, and metakaolin. In this study, 13 different combinations were created ...

Free vibration and buckling of functionally graded porous beams using analytical, finite element, and artificial neural network methods
(Springer, 2023)
In this study, an analytical solution based on the first-order shear deformation theory was performed for free vibration and buckling analysis of functionally graded porous beams (FGM-P) subjected to various boundary ...
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 ...
The contact problem of a functionally graded layer under the effect of gravity
(Wiley, 2023)
This paper considers the continuous and discontinuous contact problems of a functionally graded (FG) layer under the effect of gravity. A finite distributed load is applied to the beam from the top and the beam is placed ...
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 ...
A novel framework for strength prediction of geopolymer mortar: Renovative precursor effect
(Elsevier, 2023)
Concrete is the most used building material today as it has many advantages due to its structure. Geopolymer composites could potentially replace concrete in the future due to the demands of the construction industry. The ...
