Field Degradation – the Effect of Economic Activity in Mining Basin Oltenia – Reconstruction Possibilities

The paper aims to identify the impact of pollution phenomena on fields through extraction activities in MiningBasin Oltenia, to present the main physical-chemical properties of geological deposits brought at light throughexcavation and experimental results obtained in main crops, and also to make suggestions concerning possible solutionsregarding the ecological reconstruction of fields left free of economical assignments. An area of 17,257 ha is affectedby extraction activities from Mining Basin, out of which: 13,390 ha are affected by extraction surface activities, and3,867 ha are affected by extraction underground activities. On this surface, all the elements that include the notion ofsite have been modified: relief, vegetation, hydrology, surface geology and soils. On assembly, in Mining BasinOltenia, 60% from the geological materials brought to light through excavation and waste dumping have an averagetexture (L-LN-LA), with a good and very good suitability for productive agricultural and forestry activities. Thedifference of 40% is with a reduced suitability or non suitable.
