Abstract : INERIS works for 3 years on the characterization of O2-deficient and CO2-enriched gas production and migration processes above a former coal mining area where gas emissions occur at surface and which is close to a peat bog. The main objectives of this work were to determine the composition and origin of the emitted gas and the dynamics of its migration from the subsurface rock strata to the surface.
