28.08.2017The proposed open cast mine would produce about 11 million tons of coal (for the 1500 MW coal fired power plant), and demonstrators made a point that this represents over 30 million tons of carbon dioxide. The link to climate change has been very explicit in the campaign, as in some many other actions in Europe on "leaving coal in the hole".

The coal face is the section of the seam that is being worked. Coal is sliced away from the face, drops onto a metal conveyor (panzer) and is transferred to a belt conveyor to be carried back to the shaft or surface. As coal is removed from the face, the face advances and at the same time all the equipment has to move forward also.
