During the centuries, French mining activity contributed, for a large amount, to the national industrial
development. During the last few decades, under the combined effect of the resources exhaustion and
international competition, the very large majority of French mining sites gradually closed down.
Formerly symbol of pride and solidarity, mining activity is now frequently associated with post-mining
harmful effects. As a matter of fact, the mine closure do not result in the complete and definitive eradication
of risks for people, activities and goods located in the area of influence of abandoned mines.
Thus, during the period, which follows exploitation and traditionally called "post-mining", many disorders
may develop, sometimes just after mine closure but sometimes quite long time later. In addition to potential
instability development (subsidence, collapses), some abandoned mining sites can be affected by severe
hydrogeological phenomena (floods), dangerous mine gas emissions on surface or environmental
degradation (ground or water pollution).
The paper presents briefly the French mining historical context that leads to the present situation. It then
identifies and describes the major kinds of residual risks and harmful effects that may affect the abandoned
French mine sites. The national prevention policy is then discussed, explaining the French mining legal
scope recent evolutions as well as the major prevention programs that are developed on the national territory.
Finally, a short description of the post-mining risk management organisation is given to explain the co-
ordination between public services or establishments involved in the risk management process.
