Abstract

The closed mines are likely to release into atmosphere polluting or/and dangerous gases. The detection and hazard evaluation of those emissions are a complex problem. In order to quantify and qualify these gas emissions and check gas migrations special measuring methods are required. The research done at INERIS resulted in a reliable and appropriate methodology using a flux chamber. This methodology is intended for detecting, quantifying and qualifying gas discharges, but can also be applied to verify the effective-ness of the preventive means used for reducing emissions (sealing operations, gas drainage, etc.).The method has already been applied in an operational manner for diagnosis and appraisal on a number of sites (old mines, landfills, etc.). Although originally designed for measuring methane flows, it is fully useable in or transpos-able to any similar situation of gas flows emitted by the ground, subject possibly to some specific modifications.
