Additivity effect on properties of cemented coal fly ash backfill containing water-reducing admixtures
(Elsevier Ltd, 2021)
Cemented coal fly ash backfill (CCB), a flowable structure of coal fly ash, binding agent and mixing water, has been often employed in mining operations to offer ground support as well as waste disposal solutions. An ...
Effects of mineral additives and age on microstructure evolution and durability properties of sand-reinforced cementitious mine backfills
(Elsevier, 2022)
Cementitious paste/mine backfill (CMB/CPB) is a creative way to proficiently decrease the sum of sulfidic tailings. However, considering them as minor raw material and inadequacies in their gradation, OPC (costly and ...
Physico-chemical and micro-structural behavior of cemented mine backfill: Effect of pH in dam tailings
(Elsevier, 2022)
The tailings created during ore processing have been a serious problem for mining companies and environment since it is a challenging task to effectively manage these highly voluminous/dangerous tailings. Therefore, several ...
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. ...
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 ...
Numerical study on microscale and macroscale strength behaviors of hardening cemented paste backfill
(Elsevier, 2022)
Computer aided optimization of cement-based materials proportion can accurately quantify the accompanying microstructure evolution, material composition, and the mechanical properties changes. However, no relevant research ...
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 ...
Sodium silicate effect on setting properties, strength behavior and microstructure of cemented coal fly ash backfill
(Elsevier, 2021)
Representing an engineered mixture of coal fly ash, cement and water, cemented coal fly ash backfill (CCB) is typically employed for filling the openings created after coal excavation in the earth. A high rate of productivity ...
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 ...
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, ...
