mines depending on the nature of the mine itself. Open pit / open cast mines are quite often allowed to fill with water to form pit lakes. Pit walls are battered back to angles that make them safe and stable and the pit void is left to in-fill via inflow of surface and / or groundwater. Some treatment of the pit lake water (e.g. lime addition ...
