چکیده
The failures of tailings dams have a major negative impact on the economy, surrounding properties, and people’s lives, therefore monitoring these facilities is crucial to mitigate risk failure, but this can be challenging due their size inaccessibility. In work, deformation processes at ?elazny Most dam (Poland) were analyzed using satellite Ad-vanced Differential SAR Interferometry (A-DInSAR) from October 2014 April 2019, showing that affected by both settlements (with maximum rate 30 mm/yr), horizontal sliding in radial direction with respect ponds. load pushing forward along glacio-tectonic shear planes located depth, Pliocene clays, causing displacements up mm/yr, which could lead passive failure dam. measured been compared ones observed situ data 90s 2013, available literature. outcomes indicate intense localized deformations occur eastern northern sectors dam, while western sector deforming evenly. Moreover, although had slowdown 2010 until it continued 2019 recovered intensity. upper recent embankments are settlements, possibly lower consolidation degree most larger thickness compressible materials.

Floods 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...
متن کاملStudy of Aluminum, Copper and Molybdenum Pollution in Groundwater Sources Surrounding (Miduk) Shahr-E- Babak Copper Complex Tailings Dam
Interpolated contour maps drawn for aluminum, copper and molybdenum in downstream monitoring boreholes of water dam in Miduk Copper Complex and the values of pH, redox potential (Eh) and distance from water dam indicate different trends of variation and behavior of these three elements in downward groundwater resources. As these maps exhibit, aluminum is dominant in the most alkaline (pH = 9-11...
متن کاملDeposition of Copper in the Eutrophic, Submontane Dobczyce Dam Reservoir (southern Poland) – Role of Speciation
In order to better understand Cu behaviour in the submontane, eutrophic Dobczyce dam Reservoir (southern Poland), speciation measurements of Cu in the water and the sediment were conducted. To investigate the partitioning of Cu in the main components of the sediment, a scheme of VI-step sequential extraction was used. In addition, other physical and chemical parameters of the water, such as tem...
متن کاملLarge-Dimensional Shells under Mining Tremors from Various Mining Regions in Poland
In the paper a detailed analysis of the dynamic response of a cooling tower shell to mining tremors originated from two main regions of mining activity in Poland (Upper Silesian Coal Basin and Legnica-Glogow Copper District) was presented. The representative time histories registered in the both regions were used as ground motion data in calculations of the dynamic response of the structure. It...
