Coal open cast mining also resulted in the destruction of the habitat of the scenery; as it leads to removal of trees and pollution of air and water in surrounding the mines. Also, Coal mining leads many people to displace; as a result of the pitting of the earth brought about by underground mining.

During the seventeenth century 'Bells Pits' was the type of mining used. This consisted of bore holes being dug into the ground to search for coal. Shafts were dug about fifty feet apart and were joined by an underground tunnel to allow the circulation of air. The coal was extracted from each side of the passage.

Types of coal. Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce. The rank of a coal deposit is determined by the amount of pressure and heat that acted on the plants ...
