Effect of magnetic induction intensity and steel fiber rate on strength improvement of cementitious filling composites
(Elsevier, 2024)The underhand cut-fill backfill mining manner (UCFBMM) is widely employed in nonferrous metallic mines, and stability of the artificial backfill top plate directly determines the safety of operators and equipment, which ... -
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 ... -
Investigation on the flexural strength, failure pattern and microstructural characteristics of combined fibers reinforced cemented tailings backfill
(Elsevier, 2021)The brittleness of the cemented tailings backfill (CTB) can easily cause collapse, which seriously threatens the safety of underground mining workers and equipment. Studies have shown that fibers can improve the ductility ... -
Polypropylene fiber effect on flexural strength, toughness, deflection, failure mode and microanalysis of cementitious backfills under three-point bending conditions
(MDPI, 2023)Cemented tailings backfill (CTB) is continually practiced in a large number of metallic mines for re-filling underground ore extraction areas. Re-filling these areas can boost the security of mining teams during construction. ...
