DEWATERING AND GROUNDWATER CONTROL
(3) An important facet of dewatering an excava-tion is the relative risk of damage that may occur to the excavation, cofferdam, or foundation for a struc-ture in event of failure of the dewatering system. The method of excavation and reuse of the excavated soil may also have a bearing on the need for dewatering.

Paste Backfill Fundamentals
Paste backfill is prepared by dewatering flotation tailings from a lead-zinc concentrator. The tailings are partially classified with a hydrocyclone to increase thickening and filtration rates. After thickening to 65% solids, a standard vacuum drum filter produces filter cake with 13% moisture. The filter cake is stored in a bunker and ...

In modern mining, waste material is often backfilled into underground voids or open pits after the precious minerals are extracted. Such backfill practice has been well adopted in various mining methods, i.e. cut-and-fill (Henderson et al., 1998), sublevel opening stoping (Emad et al., 2015), and open pit mining (Lu et al., 2018).Backfill has proven to be an environmental-friendly, cost ...
