[This listing of coal mines and coal companies has been researched and complied from various sources by Raymond A. Washlaski, Historian: newspaper articles, Pennsylvania Bureau of Mines Reports, county histories, township histories, Pennsylvania Geological Survey reports, topographical maps, personnal accounts of coal miners, etc., etc.]
Very few coal company employee records exist today.  Most Coal Company employee records have been lost or destroyed after the mines were closed. If you have mine records or know of the location of coal company employee records please let us know.

Your help is needed to preserve our coal mining heritage.
