Hydrogeological Conditions In Amynteon Open Lignite Mine And Design Of Dewatering Measures

The hydrogeological conditions of Amynteon open lignite mine, West Macedonia, Greece, are very complex and sensitive. They are characterized by the existence of four lakes, the presence of quaternary and Pliocene unconsolidated sediments, above the lignite seams, which contain highly permeable sandy aquifers and a huge aquifer in the carstified bedrock of the basin.Based on numerical ground water simulations of Amynteon basin, a dewatering scenario has been developed. The pumped out water is distributed to the consumers of the area, in order to eliminate inevitable environmental impacts.
