The mining contractors arrived to assess the dam that evening. They assessed the damage, and were about to warn the local town. However, they had no time. A loud …
En 1994, la digue de stériles de la mine d'or de Merriespruit en Afrique du Sud s'est rompue causant 17 pertes de vie. L'investigation après rupture n'a fourni aucune explication quant à savoir pourquoi cet écoulement catastrophique s'est produit, en contradiction avec les expériences antérieures de rupture de digues de stériles de mine …

Bloemhoek and De Bron Merriespruit are both gold projects, which form part of the Southern Free State (SOFS) exploration project area. Sibanye-Stillwater's subsidiary, WitsGold (Pty) Ltd. (WitsGold), was granted a mining right under DMRE Ref No FS30/5/1/2/2/10005 MR to extract gold, silver and uranium from a 170.22km²area.

In fact, the mining industry has experienced several significant dam failures in the recent history: the Merriespruit (South Africa) gold tailings spill resulted in 17 fatalities in 1994 (Fourie ...
Tailings ponds are one of the three major production facilities in metal mines. The volume of tailings increases year by year, but the storage capacity of existing tailings ponds is limited. Therefore, tailings dams must become more fine-grained and larger. The potential hazard they represent should not be underestimated. This paper …
Kennedy et al. (2020) observed a similar retrogressive landslide failure in a sensitive clay model slope. It is hypothesized that the Merriespruit tailings dam experienced a similar retrogressive ...
The Merriespruit No. 4 tailings dam was part of the Harmony Gold Mine in South Africa (Fig. 3). The dam was raised in the upstream direction with a ring-dyke configuration. The impoundment was divided into a northern compartment (Fig. 3), a southern compartment, and a smaller emergency compartment.
La rupture de la digue de stériles de la mine d'or de Merriespruit en 1994 en Afrique du Sud était inhabituelle en ce que jamais auparavant une digue de stériles de mine d'or en Afrique du Sud ne s'était rompue de façon aussi catastrophique. On croyait de façon conventionnelle que les stériles de mines d'or montreraient toujours des ...
M.Sc. The Merriespruit Tailings dam disaster killed seventeen (17) people and covered a part of ia with approximately 2.5 million cubic metres of tailings, causing such an emotional uproar that all resources were focused on repairing the dam and addressing some of the social issues. Little attention was given to the environment. The …

Water mismanagement was to blame that caused 600,000 m3 of tailings (1.2 Million tonnes) to mobilize out of the impoundment where the flow eventually stopped 2 km away in the town of Merriespruit (Penman …
For example, 17 people lost their lives due to the failure of the Merriespruit mine tailing dam in South Africa (Fourie et al., 2001). Moreover, many metallic elements are present in tailings and ...
Based on research carried out at 67 tailings dams in Spain: (1) tailings dams contain alternating sedimentary layers with contractive and dilative geomechanical behaviours; (2) tailings saturate quickly but drain more than 10 times slower due to the high-suction capacity of the porous sediments (2–300 MPa); and (3) over the long-term, a …
