Influence of 3D-printed polymer structures on dynamic splitting and crack propagation behavior of cementitious tailings backfill
(Elsevier, 2022)
Originally developed for polymer materials, 3D printing is an encouraging technique to create versatile geometric shapes and high-precision construction elements from various materials. 3D-printed polymer structures are ...
Effect of height to diameter ratio on dynamic characteristics of cemented tailings backfills with fiber reinforcement through impact loading
(Elsevier, 2022)
The safety and durability of underground backfilled stopes of metalliferous mines are so crucial owing to several dynamic events such as rock bursting, loads triggered by blasting, and loading conditions under stress. ...
Characterization of macro mechanical properties and microstructures of cement-based composites prepared from fly ash, gypsum and steel slag
(MDPI, 2022)
Using solid wastes (SWs) as backfilling material to fill underground mined-out areas (UMOAs) solved the environmental problems caused by SWs and reduced the backfilling cost. In this study, fly ash (FA), gypsum and steel ...
Editorial: Advances in the design and implementation of cementitious backfills
(Frontiers Media, 2022)
Backfill plays an essential role in the most modern mining industries worldwide. It is usually applied
in the cementitious form to fill underground mined-out openings (stopes and/or voids)
Compressive fatigue behavior and failure evolution of additive fiber-reinforced cemented tailings composites
(Springer, 2022)
The ordinary cemented tailings backfill (CTB) is a cement-based composite prepared from tailings, cementitious materials, and water. In this study, a series of laboratory tests, including uniaxial compression, digital image ...
Employing U-shaped 3D printed polymer to improve flexural properties of cementitious tailings backfills
(Elsevier, 2022)
The roof stability of artificial structures constructed by cementitious tailings backfill (CTB) is one of the major aspects in the durability of underhand cut and fill mining method. This is because CTB's failure can ...
Influence of types and contents of nano cellulose materials as reinforcement on stability performance of cementitious tailings backfill
(Elsevier, 2022)
This study explores the quality of cemented tailings backfill (CTB) reinforced with diverse nano cellulose materials (NCMs) such as micro-fibrillated cellulose (MFC), hydroxylated cellulose nanofiber (CNF), and cellulose ...
