As of 2015, 1,460 coal mines were operating in the United States, including 1,055 surface mines. Coal is a major fuel source in the US, formed from plant matter that has undergone a process called coalification, turning it into the black rock-like substance we use as an energy source. Coal is found in underground in geological deposits called
