Surface mining (also known as open-pit or open-cast mining ) and quarrying are used to extract stratified mineral resources that are close to the ground surface, for example, lignite, coal, metalliferous minerals, industrial minerals, and aggregates (Read and Stacey 2001; Smith and Collis 2001 ).
Steam power was one of the most significant developments of the Industrial Revolution (1760-1840) in Britain. First invented as a pump in the 1690s, a host of inventors tweaked designs and tinkered with machinery until an efficient and powerful alternative to muscle, water, and wind power attracted commercial users.
