Performance of Coal Gangue Based Cemented Backfill

Performance of Coal Gangue Based Cemented Backfill

Coal gangue-based cemented backfill material (CGCBM) is developed for backfilling the goaf in coal mines. As fresh CGCBM slurry is generally transported into underground openings through a pipeline, and after hardening, it plays the role of supporting the overlying strata. The fluidity, stability, and mechanical (compressive strength) of CGCBM become the most important properties..200tph gold clay rotary scrubber machine applied in zimbabwe gold mining project

Characterizations of macroscopic deformation and particle

Characterizations of macroscopic deformation and particle

Abstract In solid backfilling coal mining (SBCM), the deformation resistance of crushed gangue particle material (CGPM) is critical for controlling overburden strata movement and ground surface subsidence. In engineering practice, CGPM is generally circularly compacted first by the compaction machine to reduce its compressibility. However, a systematic approach to guide the compaction ...

Utilization of Coal Gangue Aggregate for Railway Roadbed

Utilization of Coal Gangue Aggregate for Railway Roadbed

Before being applied in the roadbed, the excavated coal gangue needs to be cleaned and crushed so its uniformity and curvature coefficients are Cu 10 and 1 ≤ Cc ≤ 3 and so its combustion ingredients can be removed. Its mechanical performance is not as good as limestone, and its shear performance (shear friction angle) is somewhat worse than loess, but immobilizing and protecting the subgrade side with …
