Settling Consolidation And Desiccation Behaviour Of Coal

AbstractIn this investigation, coal tailings have been subjected to the three consecutive processes of settling, consolidation and desiccation in a large purpose-built slurry consolidometer. The results of the tests were then compared with a self-weight-consolidated specimen desiccated in a column. The result indicates that the consolidation with a constant rate of loading removes about 56 mm ...
