Geotechnical Properties and Flow Behavior of Coal Refuse under Static and Impact Loading

Geotechnical characterisation of coal tailings down the beach and constant rate of loading consolidation in a slurry consolidometer

“…The average specific gravity was found to be 1.92, with a range in specific gravity of about ±0.2. The average values were found to be consistent with coal tailings samples from Jeebropilly (Shokouhi et al 2014) and West Virginia (Yu 2015). Samples 1, 4, and 7 had relatively low values, indicating higher carbonaceous contents of around 53%, whereas the values of Samples 2, 3, and 5 are relatively high, suggesting a carbon content of around 39%.…”

Coal mining wastes valorization as raw geomaterials in construction: A review with new perspectives

“…Figure 8 shows how Ds1 may be approximated from the GSDs of samples exhibiting double fractal characteristics. The samples of Yu et al (2019) and Qiu and Sego Knowing the GSD is useful for estimating the mass and volume of aggregates needed to make CMWG-bearing construction products. This can be made even simpler when the GSD obeys a single or double fractal scaling law.…”

Seismic stability of coal tailings dams with spatially variable and liquefiable coal tailings using pore pressure plasticity models

“…The undrained shear strength of tailings and similar soils such as silty alluvial soils reported in the literature (e.g. Castro, 2003, Hegazy et al, 2004, Idriss and Boulanger, 2008, Kalinski and Salehian, 2016, Ladd and Foott, 1974, Olson and Stark, 2002, Phoon et al, 1995, Phoon and Kulhawy, 1999, Robertson, 2009, Salam et al, 2019, Yu et al, 2019 were used to establish the probability distribution for s u,cs,eq _ Rat .…”
