Device, for stabilizing environment with flooding of residual open-cast mining holes with alkaline surface water, has in slagheap region in groundwater flow direction in front of water to be protected, device for entry of alkaline liquid

摘要

In slagheap region (2) in groundwater flow direction in front of water to be protected, a number of devices for entry of alkaline liquids into groundwater region are located in row running transversely to groundwater flow direction. Their outlet openings (41) are located in region of groundwater layers. Their supply is connected via pump (3) and pipelines (4) with container (1) or release station for lime solution.
