How Coal was formed • http://www.youtube.com/watch?v=MBeXRRTGjNE
Where is the coal? Coal resources are located by geologists. It is thought that most of the world’s resources have already been located, but the continent of Antarctica remains unexploited.
How is coal mined? • Originally harvested by hand this picture from NE England (Billy Elliot territory) shows the practice still taking place in 1939.
Early pit mines • A medieval bell • pit from Scotland • (originally started • in the 1200s)
Mine Shafts (adits) • As this 16th century German drawing shows mines became more complex
Today Modern Mechanised USA More typical and traditional Pakistan
Open Cast coal mines • Much more high tech, much more impact on surface environment, much more economical.
