The shear behaviors of granular mixtures are studied using the discrete element method.
These granular materials contain real gravel-shaped coarse particles and spherical fine …

Binary granular soil mixtures, as common heterogeneous soils, are ubiquitous in nature and
man-made deposits. Fines content and particle size ratio are two important gradation …

Micro-ballast/fines mixtures were tested at various contents of coarse grains in triaxial cells
under monotonic and cyclic loadings. X-ray µCT scans were undertaken to visualise the …

In order to reduce the cost of deep mining in Guangxi Gaofeng Mine, the feasibility of
underground waste rock used for backfill and was analyzed. The tailings and waste rock …

The focus of this study was to evaluate the potential reuse of mixed mine tailings and waste
rock in water-balance covers (WBCs). Reuse of mine waste in geoengineering applications …

Study on characteristics of pressure relief by roof cutting provides useful underground stope
stability information under the nonpillar-mining approach—noncoal pillar mining with …

Cohesionless binary mixtures are commonly encountered in nature and frequently used as
filling materials in geotechnical engineering. It is known that coarse grains have a …

Because of spatial variability and complex compositions, the mechanical test results of
natural soil–rock mixtures (SRMs) are often discrete and lack reproducibility, which has …

Serious floor heave in gob-side entry retaining (GER) with fully-mechanized gangue
backfilling mining affects the transportation and ventilation safety of the mine. A theoretical …

Mine tailings are typically deposited as slurry and stored in impoundment dams. These
structures pose a serious geotechnical risk, and are difficult to successfully reclaim at the …
