TAILINGS FACILITY MANAGEMENT

Tailings dam Wikipedia. Construction of an upstream embankment begins with development of a starter dyke. The tailings are then discharged from the dam crest and form the foundation for future raises. Figure 1 shows an overview of the stages of construction. Figure 1: Upstream construction method. Downstream, ones used by Vale are the downstream and upstream construction methods Downstream Upstream The downstream shell is built on compacted soil, regardless of the type of tailings used. It is built in the direction of the water flow (downstream). The dam body is constructed using the deposited tailings. It is built in the opposite direction of the.

Most tailings dams are raised sequentially using the "upstream" construction method, following the level of the impounded tailings during the filling process (see Tailings Dam Properties).

construction methods. These embankments and the tailings dam foundation may be found comprising by different soil types with different layer orientations and thicknesses, and zones varying from fine to coarse materials that vary in density, under a wide range of … reduction of effective stresses and shear strength of tailings. Hence, during staged construction of a tailings dam, a potential dangerous stability situation can arise in which an embankment slope may become unstable. An unstable slope of an upstream tailings dam can be stabilized by using rockfill supports at the downstream toe.

ones used by Vale are the downstream and upstream construction methods Downstream Upstream The downstream shell is built on compacted soil, regardless of the type of tailings used. It is built in the direction of the water flow (downstream). The dam body is constructed using the deposited tailings. It is built in the opposite direction of the Fig. 2 Tailings dam incident history summary: number of incidents per 5 year period. While the methods used for the design and construction of embankment dams can be applied to tailings dams, there are major differences between the two types.
