This picture was taken on 18.02.1997 after
visiting the colliery in Bergkamen-Oberaden (Germany). We went underground
using Kurl 3 shaft in Luenen-Niederaden (Germany). By that we reached a
depth of -1190 metres and after using an underground chair lift we visited the
preparation of a gateroad in the Roettgersbank seam in a depth of -1450 metres.
