In mining engineering practice, cemented paste backfill (CPB) are subjected to loads at
different static rates, so it is crucial to clarify the mechanical evolution mechanism of CPBs at …

Synchronous grouting is one of the most important methods to prevent surface settlement
and water seepage accidents in shield tunnel construction. Various compositions and …

This work systematically investigates the effects of coarse aggregate (CA) type, dosage, and
slurry concentration on the backfill slurry's setting, bleeding, and hardening strength …

The study herein was intended to evaluate the rheological properties of cemented gangue
backfill material (CGBM). For this purpose, the rheological test of CGBM with fractal …

This work comprehensively investigated cemented tailings backfill composite structures
(BCS) mechanics and crack evolution mechanisms. A new crack classification method …

The mine water environment can seriously affect the long-term strength and deformation of
the backfill body, thereby affecting the stability of the goaf. In this study, the gangue …

Backfilling in goaf after pillar extraction seems to be a promising technology to help exploit
these standing pillars. This paper presents the assessment of the impact of sand-stowing …

Coal gangue, as a solid waste produced in the coal mining process, can be disposed by
being prepared into backfill materials and then filled in underground goafs, thus controlling …

The cemented gangue backfill body (CGBB) in the backfill mining is not only subjected to the
axial compressive stress of overlying strata but also corroded by mine water. To study the …
