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 …

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 …

This paper explores the grain-size composition effect on flexural and micro-structural
features of fiber reinforced cementitious tail-rock fill (FRCTRF). The FRCTRF mixes …

The interaction between cemented paste backfill (CPB) and rock at their interface plays a
crucial role in the stability of underground backfill structures. Considering the interface …

The shear behavior of the interface between rock and cemented tailings backfill (CTB) is
extremely critical to the backfill design and stability of the backfilled underground mined-out …

The mechanical strength properties of cemented tailings backfill are very important for the
safe and environmentally friendly mining of mineral resources. To check the impact of …

Natural preexisting fissures are often overlapped, and these preexisting fissures greatly
influence the stability of rock mass engineering; hence, it is necessary to investigate the …

The shear performance of the rock-CPB interface is the basis for in-depth understanding of
the arch effect of CPB. In this study, the rock-CPB sample was prepared for direct shear test …

This paper studies mechanical properties and energy damage evolution of fiber-reinforced
cemented sulfur tailings (CSTB) backfill. The effects of fiber length and fiber content on the …

In recent years, with the improvement of construction safety requirements in deep well
mining, the backfill mining method has been widely used. However, the strength of paste …
