Les Plans de Prévention des Risques Miniers

Abstract : INERIS has been involved for many years in supporting the French public authorities in defining national policy for preventing and managing post-mining risks. In order to properly identify and manage such risks, the French authorities have developed a powerful operational regulatory tool: MRPPs (Mining Risk Prevention Plans). MRPPs aim to identify the most sensitive areas subject to“post-mining hazards” and to define the technical and regulatory rules capable of managing the principles of future urban development on the surface (Didier and Leloup, 2005). INERIS has drawn up, on behalf of MinEFI (French Ministry in charge of Industry) the methodological guide for completing MRPPs. INERIS is also in charge of coordinating,within the International Society of Rock Mechanics, an experts’ commission involved in analysis and risk management related to post-mining. Since 1999 when the first MRPPs were initiated, INERIS, in association with GEODERIS, has carried out the analysis and mapping of mining hazards on more than 40 mining sites (coal and iron basins, polymetallic sites, etc.) distributed throughout France. To these must be added the whole Lorraine iron basin (more than one hundred communities concerned). Different kinds of surface instability hazards have been mapped (sinkholes, subsidence, landslides, etc.) for all of the investigated sites. In most cases, surface gas emissions have also been studied. Soil and water pollution have been analysed only on specific sites with high pollution potential such as, for example, polymetallic deposits.
