The north of France is known for its important mining resources exploited since 1720 to the end of 1990 on the Nord/Pas-de-Calais coal basin. It extends on 100 kilometres from east to west, from the Belgium boundary, and is only 15 kilometres width. The carboniferous coal deposits are trapped in between

IDENTIFICATION AND MEASUREMENT OF MINING

The coal mining under the city is carried out by 4 coalmines and up to 1987 also by the Zn-Pb ore mine, which operates on the same area, but on shallower level. The summarized thickness of mined out coal banks is 15 to 25 m in the western edges reaching 40 m in the eastern part of the area.
