Tailings dams differ from water supply reservoir dams in two significant ways—dam life design and dam construction design First unlike a dam built for impounding water which can ultimately be drained if the structural integrity becomes questionable a tailings dam must be designed to safely impound the material behind the dam in perpetuity
With the rapid growth of the mining activities inci dents of tailings dam failure have occurred frequently with five to six catastrophic cases reported annually on a global scale after 2000 8
On November 5 2015 the Fundão tailings dam at the Samarco iron ore mine in the state of Minas Gerais Brazil failed with catastrophic consequences
The Majiatian tailings reservoir in the eastern district of Panzhihua City is a vanadium titanium magnetite ore tailings reservoir Fig 1 The climate in the area of Panzhihua City belongs to a typical dry hot valley climate and the annual mean temperature and precipitation are °C and 800 mm respectively
Tailings ponds are composed of residual mining sediments and represent a high risk due to their mechanical instability A tailings dam break can cause extensive damage to the safety of downstream residents and the surrounding environment This paper introduces a collapse of the tailings dam that occurred in Tonglüshan Daye Hubei China To examine the
Tailings dams differ from water supply reservoir dams in two significant ways—dam life design and dam construction design First unlike a dam built for impounding water which can ultimately be drained if the structural integrity becomes questionable a tailings dam must be designed to safely impound the material behind the dam in perpetuity
The study area covers the basin of Gutanting Reservoir the largest backup drinking water source for Beijing in Zhangjiakou City where many mine tailings ponds are located A preliminary investigation was undertaken into tertiary prevention and control of acute water pollution risk from mine tailings ponds dams as part of the 12th five
In contrast to dams built to contain reservoirs tailings dams are progressively raised in stages for several years to decades commensurate with the rising volume of stored tailings By extrapolation from a mine area vs TSF area relationship using data from Werner et al 2020 and our independent geospatial mapping
Stava Italy In 1985 tailings dams built to store waste from flourite mining failed due to poor design and extreme water pressure Two hundred thousand cubic meters 186 462 cubic miles of
Tailings used in the tests were obtained from the #1 tailings dam of the Yongping tailings reservoir of Yongping Copper Mine in Jiangxi Province China Fig 1 There are five dams in this tailings reservoir and all were constructed using the upstream method A typical section of the #1 dam was simulated in the model tests
Rivers lakes dams reservoirs and other bodies of water artificial or not The lack of a comprehensive analysis on the suitability to install tailings dams in mining areas has motivated this study and Fig 11 shed light on the expected outcome for the Ribeirão Ferro Carvão micro basin The diagram defined areas where these depositional
The awareness of tailings dam safety monitoring has widened due to the recent disasters caused by failures of such structures The failure rate of tailings dams worldwide the percentage of failed dams out of total is estimated at % compared to the % rate for traditional water dams Most of the tailings dam monitoring guidelines suggest that the owner
Surface paste disposal SPD of waste tailings is a new disposal method while it is not suitable for the projects in rainy regions Traditional tailings disposal means a setting pond or a dam
As one indicator of their potential scale the Red Chris Mine which has operated since 2015 in the headwaters of the Stikine River maintains a tailings reservoir dam that is permitted to
A valley dammed uranium tailings reservoir that stores a large amount of tailing sand is located in the eastern part of the uranium mining area Waste rocks and effluent generated from the uranium mill tailings have led to a variety of
The coal pillar dam of underground reservoirs and residual coal in goaves have a direct impact on the quality of mine water In this paper the coal pillar dam of an underground reservoir and
Tailings containment dam failures cause severe environmental social and economic impacts Analyzing past occurrences allows society and decision makers to improve storage facility safety This study presents an overview of tailings dam failures exploring historical aspects and environmental consequences Two methodological strategies were used 1 An
Tailings dam failures cause catastrophic impact on the environment and surrounding communities Incidences of failure in the recent past have caused industrialists and researchers to seek innovative ways for proactively managing their safety and disaster mitigation
Mining activities and infrastructure expansion cause great changes to the landscape and lead to social economic and environmental impacts in the surrounding areas [1 2] Mine tailings are mixtures of crumpled rock and processing effluents that are generated during the extraction of metals minerals or coal from mines [] To avoid the formation of acid
Request PDF On Dec 1 2023 Polyana Pereira and others published Geomorphologic risk zoning to anticipate tailings dams hazards A study in the Brumadinho s mining area Minas Gerais Brazil
Mining operations lead to the production of large quantities of mineral waste such as fluid fine tailings whose disposal is rather challenging In Brazil tailings disposal is facing a critical situation due to the large accidents that took place in the last couple of years As a response to these accidents the Brazilian Mining Agency became stricter on licensing mining
