A very steep seam !


Unluckily the seams are not always situated in a horizontal position between their ceiling and their floor. Even in earlier times the coal has been extracted from very steep seams, yet. In this photo that is taken in the museum you can see how a corresponding longwall mining area looked like. It is a really impressioning imagination to work here, isn't it ?
