Leave MessageOnline ServiceDownstream design tailings storage facilities are typically suitable for areas with seismic activity and high rainfall. In addition, all tailings dams must be designed to take into account the specific environmental setting in which they are to be located, which will include grain size, slope angle and height of
Leave MessageOnline ServiceThe downstream method has evolved as a result of efforts to devise methods for constructing larger and safer tailings dams. This method produces safer dams both in terms of static and seismic loading (Azizli et al., 1995).It is essentially the reverse of the upstream method, in that as the dam wall is raised, the centerline shifts downstream, and the dam remains founded on coarse tailings

They ordinarily appear as a fluid slurry made of fine mineral particles, produced as mined ore is crushed, ground and prepared. Since the 1960s, tailings have normally been stored behind dams, referred to as upstream, downstream or

Tailings are then discharged into the dam and as the embankment is raised, each new wall is constructed and supported on top of the downstream slope of the previous section, so the dam crest moves downstream with each raise.
