New process technologies in European coal production, 1850

retellings of the Industrial Revolution, the great process technologies in coal mining were the Savery and Newcomen pumps. These machines, which later gave way to separate pumps that were connected to steam engines with Watt condensers, allowed the search for coal to run ever deeper by removing ambient water.

How it Works: Water for Coal

Storing coal-mining waste together with the water used to separate it from the coal can present a significant hazard if the impoundments ("slurry ponds") fail or the slurry breaks through into nearby abandoned mines. After extraction, coal must be transported to the power plant. While most US coal travels by train, barge, or truck, some

The remains of a number of water leats probably constructed to power water pumps for the coal mines can also be seen. However, most coal was extracted from a large number of generally small mines between Chilcompton and Mells, which worked the thin coal seams in the Lower and Middle Coal Measures. Up to nine named coal seams were exploited in

Mine dewatering

It was the first practical application of the steam engine and it was used to dewater coal and tin mines. The first reliable metal pump was created by Jzsef Kroly Hell and used in the Schemitz mine in 1749. Almost 40 years later, in 1788, the first water-independent system appears that uses a metal pump. It was installed in the German lead
