Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, ...

Building a Reinforced Earth retaining wall along a railway does not require any scaffolding, or any structural footing in front of the cladding. As a result, the wall can be built without interruption of traffic.

ground reclamation. A method proposed by Miki (1985) is to enclose cement treated coal ash piles in geosynthetic stockings on which a granular bed was laid over for the construction of embankments over soft soils. Watari et al. (1986) and Broms and Shirlaw (1987) reported the earliest application of this method for reclaiming mining waste lagoons.
