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 …

Phosphogypsum backfill mining has been gradually promoted in recent years. However,
phosphogypsum suffers from some defects that limit its further application. In this study …

The safety of mine-filled stopes is seriously affected by settlement and uneven pore
distribution of cement-based tail fill (CTF). To further improve the mined-out areas' stability, it …

Cemented tailings backfill (CTB) is continually practiced in a large number of metallic mines
for re-filling underground ore extraction areas. Re-filling these areas can boost the security …

The workability of alkali-activated coal gasification slag (CGS) based backfill materials is
critical parameter in transportation processes, while the high water demand of CGS hinders …

Efficient gangue grouting in goafs requires accurate measurement of time-dependent
rheological properties of the slurry and slurry fluidity to ensure proper transport. This paper …

Shear stress prevalence in in-situ cemented paste backfill (CPB) makes understanding
mode-II fracture behaviour and properties vital for the mechanical stability of the backfill …

To investigate the mechanism of polypropylene fiber (PPF) on the rheological and
thixotropic properties of cemented paste backfill containing mineral admixtures, the concept …

Cemented paste backfill (CPB) is a technology that has a positive impact on both the
environment and mining safety. In recent years, it has been widely applied and developed …

Cemented paste backfill (CPB) is prevented from freezing by antifreeze during transport in
subzero temperatures. However, there is yet to be a study on the mechanical properties of …
