Mine dewatering

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[2] or, if nothing else, carrying water-filled buckets manually.

Water was put in buckets and removed using rope conveyors powered by horses on treadmills.

The atmospheric engine, invented by Thomas Newcomen in 1712, combined the ideas of Thomas Savery, who he was forced to go into partnership with due to Savery's patent, and Denis Papin, using his invention of a piston.

The first reliable metal pump was developed by József Károly Hell and used in Schemnitz in 1749.

[13] The most relevant concerns with mine dewatering are related to acid mine drainage and the dispersal of contaminated water into other water fonts and the general environment becoming a serious source of pollution.
