There are three types of surface mining - strip mining, where explosives are used to remove the top layers; open pit mining when a pit is dug; and MTR mining where a whole mountain summit is destroyed. Underground mining is performed when the coal is deeper than 300ft below ground level. Coal mine workers have to carry out mining activities then.

Underground mining, sometimes called deep mining, is used when the coal is buried several hundred feet below the surface. Some underground mines are 1,000 feet deep. To remove coal in these underground mines, miners ride elevators down deep mine shafts where they run machines that dig out the coal. Read about a visit to a real underground coal ...

In particular, surface mining is used to retrieve sand, gravel, stones, coal, iron and other metals. There are five recognized types of surface mining, each with specific variations depending on the minerals being extracted. These include strip mining, open-pit mining, mountaintop removal, dredging and highwall mining.

First, increased mechanization in both Kentucky coal fields has reduced the need for labor. [8] This has become even more pronounced with the emergence of strip mining. Secondly, acid rain regulation found in the 1990 Clean Air Act Amendment has made Kentucky coal, with its medium to high sulfur content, less desirable.

In this type of mining, giant machines remove top-soil and layers of rock to expose large beds of coal. After coal extraction, the topsoil is replaced so that the area can be reused for croplands, wildlife habitats, recreation or offices.
