The tailings disposal facility at Bogoso/Prestea consists of four areas: TSF 1, which is inactive and is currently being decommissioned; TSF II cell 1 /2 for CIL tailings; TSF II cell 2A for CIL tailings and TSF III cell for flotation tailings. The total area is about 380 ha with 60 ha in active rehabilitation (Thorpe and Oboro-O‟fferie, 2009). tailings is normally far in excess of the liberated resource, and the tailings often contain potentially haz-ardous contaminants. A priority for a reasonable and responsible mining organization must be to proac-tively isolate the tailings so as to forestall them from entering groundwaters, rivers, lakes and the wind.
The collapse of a mine tailings dam and subsequent flood in SE Brazil on 5 November 2015 was preceded by a small‐magnitude seismic sequence. In this report, we explore the spatiotemporal associations between the seismic events and the accident and discuss their possible connection. Tailings are mixtures of crushed rock and processing fluids from mills, washeries or concentrators that remain after the extraction of economic metals, minerals, mineral fuels or coal from the mine resource (e.g., Fig. 1a; Hudson-Edwards et al., 2001, Younger and Wolkersdorfer, 2004, Lottermoser, 2007).

The method of tailings disposal, has a strong influence on the characteristics of the tailings mass within the reservoir and on the behaviour of the tailings dam. The presence, and the amount of the water in the voids of the tailings, is an important factor that governs several aspects of the performance and the safety of tailings dams. Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These deposits form a mineralized package that is of economic interest to the miner.
Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away.
