Participation in the Géoderis public interest group (GIP)
Since its launch in 2001, Ineris has been a member of the Geoderis public interest group (GIP), which brings together the Ministry of the Environment, Ineris and BRGM.
The Institute provides the GIP with around ten experts, mainly in the field of geotechnics. In this context, Ineris initially provided methodological support (hazard prioritisation) and installed microseismic monitoring networks in high-risk areas, primarily in the Lorraine iron ore basin and the Provence coal basin. These networks are still monitored by Ineris in real time via its Cenaris operational platform.
Ineris's support also included conducting numerous hazard studies (ground movements in nearly 1,800 municipalities and gas) of mining sites throughout mainland France, particularly in the major mining basins (Nord-Pas-de-Calais, Saint-Étienne, Gardanne, Normandy iron mines). Over the last 10 years, Ineris has continued to support Geoderis in its traditional areas of expertise (geotechnics and gas), while expanding its involvement to environmental issues that have become particularly sensitive. The Institute has thus actively contributed to the inventory of mining waste sites and assessed the health risks for sensitive former mining sites. In the field of contaminated site and soil management, Ineris provides expertise to define monitoring strategies for various environments (surface and groundwater, soil, indoor air and soil gas, etc.), develop exposure scenarios (including modelling of pollutant behaviour and transfer) and propose action plans to prevent risks in often complex and sometimes conflicting situations.
Finally, to meet certain needs of Geoderis, Ineris has developed and maintained expertise that is virtually unique in France in the fields of salt cavity behaviour, mine gas migration in complex reservoirs (Cocheren fissures, Nord-Pas-de-Calais coal basin) and mining microseismicity.
