Construction dewatering in Chalk

, 2017
Construction dewatering is often required to control groundwater when excavations are made in Chalk, which is a relatively soft fissured limestone. The rate of groundwater inflow and any associated instability in an excavation are controlled by the ...

Fine Coal Dewatering

, 1997
Fine coal constitutes a relatively small portion of a product stream in a coal cleaning plant. However, its processing cost is approximately three times higher than the cost of processing coarse coal. Therefore, many coal companies chose to discard the

Freeze-Thaw Dewatering and Structural Enhancement of Fine Coal Tails

, 1995
: An 18.2-ha coal tailings impoundment that reached full capacity in 1989 has since been undergoing reclamation activities. The impoundment is sectioned into coarse, intermediate, and fine tails regions. The fine tails region, which consists of saturated
