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 …

Understanding the porosity/pore linkage and strength properties of cementitious mine
backfill (CMB) is essential for the design of underground mining filling. Adoption of new …

Tensile and shear fracture behaviors of fiber-reinforced cemented paste backfill (FRCPB)
play critical roles in the safe and cost-effective engineering design of underground mine …

Dynamic fracture behavior of rock-based layered material containing a pre-existing crack
was investigated, which is crucial to evaluate the stability of rock-based systems. Dynamic …

The curing temperature-dependent cement hydration causes the nonlinear evolution of
fracture behavior and properties of fiber-reinforced cemented paste backfill (CPB) and thus …

In the downward filling mining method, the fracture of the roof of the filling body with cracks
will seriously endanger the lives of the workers. In this study, uniaxial compression tests …

External sulphate attack (ESA) interferes with spatial changes in fracture toughness of
cemented paste backfill (CPB) and affects its mechanical stability. Large-scale curing …

In this paper, the mechanical damage characteristics and energy dissipation patterns of fibre-
reinforced cemented tailings backfill (FRCTB) under different strain rates are investigated …

Layered cemented filling leads to a layered composite structure of cemented tailings backfill
(CTB) composed of high-strength top and bottom layers, as well as a low-strength middle …

Cemented paste backfills (CPB, comprising waste tailings, hydraulic binder, and water) are
essential for safe and efficient underground mining production. Once delivered into …
