Analyzing the microstructure of cemented fills adding polypropylene-glass fibers with X-ray micro-computed tomography
(Elsevier, 2023)
Fiber reinforced cementitious tailings backfill (FRCTB) is progressively employed in mining industry due to its high strength/stiffness-to-weight ratio. However, the wide use of the FRCTB technique requires further study ...
Innovative mine backfill materials and structures
(Taylor & Francis Ltd., 2023)
The mining of natural resources forms three broad classes of mine waste: waste rock, tailings, and coal gangue.
A New index and control method of filling effect for cemented paste backfill in coal mines
(Taylor & Francis Ltd., 2023)
The scientific filling effect characterization is very important for backfill mining. A new filling effect index, the final backfill ratio (FBR), is proposed through experimental tests and theoretical analysis, and the ...
Polymer shape effect on damage evolution, internal defects and crack propagation of 3D-printed polymer-based cementitious backfill
(Elsevier, 2023)
The strength property and damage mode of cementitious tailings backfill (CTB) are governed by its structural characteristics in the presence of the microstructure/internal defect effects. However, this correlation is still ...
Enhancing flexural property and mesoscopic mechanism of cementitious tailings backfill fabricated with 3D-printed polymers
(Elsevier, 2024)
Backfill mining, one of the most common methods for removing hazardous tailings, is performed on cementitious tailings backfill (CTB), which can be employed to fully discard risky tailings while diminishing the ecological ...
Polypropylene fiber's effect on the features of combined cement-based tailing backfill: Micro- and macroscopic aspects
(MDPI, 2024)
In undercut-and-fill mining, backfills show weak tensile strength and poor ductility properties since they act as artificial pillars to support stope roofs. Hence, the enhancement of the stability of mining structures and ...
Reinforcing effects of polypropylene on energy absorption and fracturing of cement-based tailings backfill under impact loading
(Springer, 2024)
Polypropylene (PP) fiber-reinforced cement-based tailings backfill (FRCTB) is a green compound material with superior crack resistance and has good prospects for application in underground mining. However, FRCTB exhibits ...
