standing of the mechanical properties of mine tailings is critical for the design of a tailing dam. In addition, numerical simulation has proved to be a useful tool for the analysis of the seepage, de-formation, seismic response, as well as the assessment of stability of tailing dams. The required input parameters for such numerical

THE FUNDÃO MINE TAILINGS DAM The Fundão Mine Tailings Dam was constructed to retain sand and slimes tailings that were produced from the benefication of iron ore. Transported in slurry form, the sand tailings (sands) comprised sand and silt-sized particles, which generally allowed for rapid water drainage following their deposition. The sands ...
The West Rand Consolidated Mine is near Johannesburg, South Africa. The site was first discovered in 1887. The West Rand Consolidated Mine is a underground mining operation. Initial production took place in 1908 and overall output was considered to be large size. Mine operations consist of 2 distinct underground workings. There are a total of 4 shafts.

Accompanying mining operations is the construction of tailings dams needed to contain the mine wastes. These tailings dams were built across the river beds in various parts of Benguet.
isting tailings retention dams. As part of this investigation, undisturbed samples of tailings from 15 dam sites were taken and tested in the laboratory. From the results of these tests, new design formulae were established to evaluate the in-situ strength of tailings deposits under . 53 . seismic loading conditions. The following sec
07-05-2015· Mine sites typically manage tailings by constructing ponds secured by dams. According to the web site miningfacts.org, another strategy is to produce thickened tailings, which are pressed or have chemicals added to remove excess water. Thickened tailings can be mixed with cement and used in construction or as backfill in underground mines.
The following practices or technologies could make mine dumps and slimes dams practical in habitable environments: Rock cladding of tailings dams, this has been used to control wind and water (rainfall) erosion of the Doornkop tailings dam in the Westrand, Randfontein Estates gold mine [8]. Rock cladding can also be
28-08-2019· Stepping up safety in managing miners' tailings dams. Robeco is stepping up its efforts to improve safety in the mining industry after 248 people were killed in a Brazilian tailings dam collapse this year. Engagement specialist Sylvia van Waveren explains how an investor initiative is taking action to prevent further disasters.
Canadian Natural is also investigating tailings revegetation, such as the effects of NST on plants growth during reclamation. Along with other oil sands operators, we are also researching the viability of pit lakes for treating process-affected water and sequestering tailings, as part of oil sands mine closure plans.
Design, and Analysis of Tailings Dams (BiTech Publishers Ltd. 1990). This is particularly true of certain concepts and organizational emphases, as well as many of the tables and figures. In some cases, this document presents a digest of Vick's overall approach to tailings dam planning and design.

About the Global Tailings Portal. The Global Tailings Portal, launched in January 2020, is a free, searchable database with detailed information on more than 1,800 mine tailings dams around the world. It enables users to sort data about tailings dams by location, company, dam type, height, volume, and risk, among other factors.

17-02-2021· 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 stationary flow regime is attained within a tailings ...

Tailings dams are generally segregated by the coarseness of the material (coarse fraction near the spigot) and if a particular area of a dam is too coarse for pumping then blending is required. Once the required density is obtained in the sump and screening has prevented large objects from passing, the slurry is then pumped to thickeners and the underflow is reprocessed in the plant.
