Declining historical mining districts have obtained large profits from
mineral and metal extraction. However at present, in addition to cash
problems which usually lead to mass unemployment, they are suffering
their own environmental problems (acid lakes, metal contamination, def
orestation, dangerous pits, etc.) and the pressure of environmental la
ws to minimize these disasters. It is often left to tourism to palliat
e these situations. However; the creation of interesting recreational
activities (in-mine trips and visits to historical mining-museums) run
into problems such as the geomechanical instability of old mines and
the frequent scarcity of local historical objects. The resource-exhaus
ted and over-populated mining districts of Europe provide many example
s. Consequently, we propose changes in the environmental mining laws f
or historical mining districts to include these new points: the preser
vation of an in-mine space which will be safe for visitors and the sto
rage of a good collection of historical mining objects.
