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' screwwas also historically used to pump water out of mines. Wh

25.10.2021 · Flooding of a long wall (an automated form of underground coal mining along flat seams) can be particularly costly as the equipment cannot be moved. In mining insurance, losses associated with flooding are, therefore, assumed to exceed losses due to ground failure. Many mining operations use a system for dewatering rainfall with diesel-powered, self-priming
