Coal Mining. Print. Coal is a solid that, if we are to use it, must be extracted from the earth. This is coal mining, going into the earth to remove coal for our consumption. The basic steps of mining and processing coal are described below. There are two general methods of coal mining: surface mining and underground mining.
Big Muskie near Chandlersville, Ohio, July 1974. Big Muskie was a coal mining BucyrusErie dragline excavator owned by the Central Ohio Coal Company (formerly a division of American Electric Power ), weighing 13,500 short tons (12,200 t) and standing nearly 22 stories tall.
