U.S. Waterways Polluted by Coal Mining | Environmental Pollution Centers

Coal mining is a practice that negatively impacts all kinds of waterways from rivers, streams, lakes and drinking water supplies. The tendency among the large public is to associate coal with having damaging effects on air rather than on water, yet during all the stages of processing it, the rock affects water bodies in the proximity of the place in which it is being exploited.

Coal mining

Coal mining greatly increased during the industrial revolution and the following decades. The main mining areas were around Aachen, the Ruhr and Saar area, along with many smaller areas in other parts of Germany. These areas grew and were shaped by coal mining and coal processing, and this is still visible even after the end of the coal mining.

The coal mining life cycle

Coal haulage, the transport of mined coal from working faces to the surface, is a major factor in underground-mine efficiency. It can be considered in three stages: face haulage, which transfers the coal from working faces; intermediate haulage, which transfers the coal onto the main haulage; and the main haulage system, which removes the coal from the mine.
