What Is Coal Refuse ARIPPA

Coal refuse is a legacy of previous coal mining and consists of lowquality coal mixed with rock, shale, slate, clay and other material. Also known as waste, culm, gob and boney, it was discarded as a “waste” during the original coal extraction process and randomly disposed in piles near the mine sites.
