Design of coarse tailings and dry ash disposal facilities

The thermal coal industry produces bottom ash and fly ash which are usually codisposed onto one facility. The fly ash is a predominantly siltsized material which typically makes up 80% of the waste produced, the remaining material; the bottom ash is normally a sand size. In some cases, the ash is hydraulically disposed

 · Crushed stone compaction piles are widely used for soft ground improvement because the installed piles improve both overall composite capacity and discharge capacity. However, discharge capacity declines when clogging occurs due to clay penetrating into the voids of crushed stone compaction piles over time. In this study, research was performed to reduce clogging and minimize .
