A primary challenge in the mining industry is how to extract mineral and metal resources in a
cost-effective and environmentally-friendly way. To help mitigate the environmental issues …

Rock fracture toughness is a critical parameter for optimizing reservoir stimulation during
deep resource extraction. This index characterizes the in situ resistance of rocks to fracture …

Abstract Reactive Powder Concrete (RPC) is a relatively new composite concrete material
type. The development of RPC aims to achieve a microstructural improvement primarily …

The shear behavior of backfill-rock composites is crucial for mine safety and the
management of surface subsidence. For exposing the shear failure mechanism of backfill …

The crack initiation and propagation behavior of interface crack under impact are of great
significance for evaluating the stability of rock-concrete system and other layered structures …

In the mining industry, backfill is used to stabilize mined-out underground excavations, and
backfill made from mine tailings has the added advantage of being sustainable and …

The compression properties of cementitious backfill composite (CBC) is strong, but their
tension properties are weak and presents little ductility because of their low fatigue crack …

The application of CPB (Cemented Paste Backfill) can realize the clean, efficient, and safe
mining of underground metal mines. Clear understanding on the triaxial mechanical …

The interfacial transition zone (ITZ) exists between the coal gangue aggregate and the
cement-fly ash matrix in the cemented coal gangue backfill (CCGB). The ITZ is considered to …

The effect of temperature (T) on fracture characteristics of granite was investigated in this
study under four mode mixites. Notched semi-circular specimens were prepared and …
