Coal Waste in Civil Engineering Works: 2 Case Histories ...

The coarse refuse is used to construct the impounding structure while the filter cake ("mud") from the plant is placed upstream of the dam. The mud is produced by extruding the water from the coal refuse fines, and is stored in a bin until it can be hauled to the refuse site. The mud bin capacity is approximately four truckloads.

Mountain Coal Project Description Summary

Coal Refuse and slurry What is Coal Refuse? After coal is mined, the raw coal must be processed and cleaned to prepare it for combustion. The first basic step is to put the raw coal through a series of shakers that separate rock material from the coal and results in a solid waste, generally called "coarse coal refuse."

Closure of coal refuse slurry impoundments is accomplished by pushing out coarse coal refuse (CCR) from the sides of the slurry impoundment over the surface of the fine coal refuse (FCR). However, this activity can lead to substantial heaving of the slurry as the CCR is pushed out. The actual magnitude of the heaving is difficult to predict.
