Environmental issues from coal mining and their solutions

The production of coal mining wastes can be decreased 10% by reuse of mining wastes as underground fills, or by using the waste as fuel for power plants or for raw material to make bricks or other infrastructure materials. The proper use of mined land must be decided in terms of local physical and socio-economical conditions.

Coal - Encyclopedia.com

May 21, 2018 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.
