Coal Mining Methods. The method used to mine coal depends on the terrain and the depth of the coal. Before the early 1970s most coal was taken from underground mines. Since then, coal production has shifted to surface mines. (See Table 4.1 and Figure 4.2.) Underground mining is required when the coal lies more than 200 feet (61 m) below ground.
