The variation of qt in sands with varying fines con-tent and fines plasticity has not been as well studied as for clean sands, including how the fines content

The important coal properties influencing fines generation shall also be identified. The listed in Table 5 are the properties of different types of coals that have been considered for the analysis. To characterize the effect of coal properties on the generation of fines, the overall fines generation for a particular coal type was defined.
