Open pit reclamation is the final phase of mining activity to which every owner of the mining company is obliged. The selection of the target concept of the direction of decommissioning and reclamation of such excavation must be preceded by an analysis of the most optimal effects resulting from socio-economic and technical-environmental needs. The main research area on which research is being conducted is the sand open pit in the final phase of operation, whose excavations are simultaneously recultivated by their ...

An important element in forecasting impact on groundwater of post-mining wastes used for open pit reclamation is the quantitative assessment of the absorptive capacity of deposited wastes (mainly Carboniferous rocks) and the volume of free rock debris as a zone more susceptible to mineral weathering and pollution leaching. These tests must be carried out simultaneously with the simulation on a laboratory scale of changes in the filtration coefficient of loose materials depending on the depth of the dumping ground ...

In the framework of the work, the authors conducted an analysis of the possibilities of modifying the selected rank method to evaluate the groundwater vulnerability to cpollution in the area where a source of contamination is at least partly under the surface and the groundwater interact directly with it. Such an object is among others the CTL Maczki-BпїЅr sand mine, the workings of which are reclaimed with gangue (post-mining waste) from coal mines. The analyses of the groundwater vulnerability to pollution using...
