Non-linear mechanical characteristics of tailings in large-scale high tailings dams
نویسندگان
چکیده
The non-linear mechanical characteristics of tailings under high pressure are the research foundation large-scale dams. Considering stress caused by tailing ponds, consolidated drained triaxial shear tests were carried out. deterioration mechanism mechanics was revealed particle crushing. test results show that sample density has a great influence on volumetric strain low pressure. However, is not related to strength significantly non-linear. internal friction angle can still be obtained traditional linear Mohr–Coulomb criterion and power function Mohr criterion. crushing occurs only at but also value breakage index increases with density. affected breakage. linearly increasing strength, indicating deep part dam prone crushing, which affects stability dam.

Trends in the stewardship of tailings dams
Tailings impoundments frequently represent the most significant environmental liability associated with mining projects, both during the operational and decommissioning phases of a project. A spate of recent and well-publicized incidents involving tailings impoundments has placed the mining industry in general, and those responsible for tailings impoundment design and safety in particular, unde...
متن کاملGeo-Seismic Environmental Aspects Affecting Tailings Dams Failures
Seismic performance evaluations of tailings dams are essential for characterizing the geoenvironmental risks posed by these earthen structures, which should include the geotechnical hazards implied by slope instability failure, free board loss and the potential release of contaminants. The observed damage is more important when liquefaction occurs on the dam body and foundation, which often lea...
متن کاملSuperiority of Filtered Tailings Storage Facility to Conventional Tailings Impoundment in Southern Rainy Regions of China
In order to evaluate the superiority of a filtered tailings storage facility (FTSF) to conventional tailings impoundment in the southern rainy regions of China (SRRC), the tailings slurry leakage and pollution accident occurring at the wet tailings dam (WTD) of Yinshan were analyzed, the properties of the tailings were tested in a laboratory, and the possibility of tailings liquefaction was eva...
متن کاملFloods from tailings dam failures.
This paper compiles the available information on historic tailings dam failures with the purpose to establish simple correlations between tailings ponds geometric parameters (e.g., dam height, tailings volume) and the hydraulic characteristics of floods resulting from released tailings. Following the collapse of a mining waste dam, only a part of tailings and polluted water stored at the dam is...
