Analysis of Plant and Soil Restoration Process and Degree of Refuse Dumps in Open-Pit Coal Mining Areas

open access: yesInternational Journal of Environmental Research and Public Health, 2020
Vegetation and soil restoration are the key to ecological reconstruction in the damaged areas of open-pit coal mining areas. Ecological stability is an important indicator of the degree of ecological restoration. In this study, the ecological stability and the process of plant and soil restoration were investigated at different refuse dumps in three ...

Determining the Safe Distance for Mining Equipment Operation When Forming an Internal Dump in a Deep Open Pit

open access: yesSustainability, 2023
In the surface mining of mineral deposits, land resources suitable for agricultural purposes are inappropriately spent in large volumes. When mining deep open pits, overburden rocks are mainly transported to the surface. The optimal solution for reducing

Heavy Metal Pollution and Health Risk Assessment of Soils From Open Dumps in the Metropolitan Area of Buenos Aires, Argentina

Environmental Monitoring and Assessment, 2020
We assessed heavy metal pollution and potential health risk by ingestion of soil in six open dumps in the Metropolitan Area of Buenos Aires (MABA), Argentina. For the determination of Cd, Cu, Ni, Pb, Zn, Hg, and Cr, soil samples were taken from the first 10 cm using sampling grids installed between the boundaries of the waste final disposal sites and ...

Using Time Series InSAR to Assess the Deformation Activity of Open-Pit Mine Dump Site in Severe Cold Area

Journal of Soils and Sediments, 2021
There are a large number of open-pit coal mines in the world, and their dependent, heterogeneous dump sites are one of the world’s largest chronic waste concerns. The long-term existence of dumps is vulnerable to non-uniform deformation and erosion simultaneously, seriously threatening also the surrounding geological and ecological security.
