Mine Machines, Coal Cutting In the early days of using coal, loose coal would be gathered by hand where coal seams reach the Earths surface (outcrop). Hand tools such as picks were used to get the coal. As seams were mined underground, sharpened hand tools were the standard equipment and continued to be used in small mines until the 1950s.

#0183;#32;For extracting coal which lies close the surface, huge dragline shovel machines remove the topmost layers of soil and rock, exposing the coal, which is then removed by smaller machines. Surface mining may involve removing sections of hills or top layers of a flat surface area. The layers of rock and dirt covering the coal are reserved for until the coal is removed, at which point the the dirt and rock is

The coal mining dragline known as Big Muskie, owned by the Central Ohio Coal Company (a division of American Electric Power), was the world''s largest mobile earthmoving machine, weighing nearly 13,000 tonnes and standing nearly 22 stories tall.
2 #0183;#32;Coal mining, extraction of coal deposits from the surface of Earth from underground. Coal has been used since the Bronze Age, 3,000 to 4,000 years ago, and was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries.
Mining is being increasingly carried out underground as open pits near the end of their mining life and new ore bodies are increasingly being identified deep underground. Constructing underground mines with the use of conventional shaft and tunnel boring machines, however, has proved to be technically challenging, expensive and sluggish.
A power shovel (also stripping shovel or front shovel or electric mining shovel or electric rope shovel) is a bucketequipped machine, usually electrically powered, used for digging and loading earth or fragmented rock and for mineral extraction. Power shovels are a type of rope/cable excavator, where the digging arm is controlled and powered by
