2. INTRODUCTION Coal was mined in America in the early 18th century, and commercial mining started around 1730 in Midlothian, Virginia. There were many coalfields, but the oldest were in Newcastle and Durham, South Wales, Scotland and the Midlands. Coal is primarily used for the generation of electricity, with much smaller volumes used for industrial process heat and in steel production. Over ...
