Flooding and gas emissions of old iron mines in lorain

Abstract : A study carried out in the iron basin of Lorraine (North-East of France) enlighted on the existence of under-oxygenated and noxious gas emissions (carbon dioxide, radon) in vast built-up areas related to abandoned mine workings. This study has been extended to other sectors of the Lorraine basin, the northern region, which is currently subjected to flooding. Specific devices were put in situ to observe the gas flow characteristics. The natural thermal convection seems to be the main phenomenon to explain the gas circulation. Noxious gas is also emitted but the intensity of the phenomenon was far less spectacular than those observed in Moyeuvre-Grande area
