Mine dewatering - Wikipedia

The act of taking water from a mine that is being operated has been done since Neolithic times. In the past it was done by using a shadoof, digging deeper dikes so that gravity would remove the water, by mounting leather water-filled buckets on water wheels or, if nothing else, carrying water-filled buckets manually. The Archimedes' screw was also historically used to pump water out of mines. Where no dewatering techniques were effective the mine had to be shut down due to flooding.
