Gases emission monitoring in a post-mining context

Abstract : Closed mines are often sources of dangerous gas emission. Flammable and/or toxic gases or deoxygenated air can be transmitted to the surface through existing aerodynamic links like abandoned shaft or galleries and fissures in rock. The gases issued from closed mines may generate public health and safety concerns and these problems are encountered for nearly all mine types. For the last 10 years, INERIS has developed in situ gas monitoring methods whose objectives are (i) to characterise gas emissions and to improve our knowledge of the processes governing their migration; (ii) to allow their risk evaluation and, eventually, to enable gas detection and alarm triggering. After briefly presenting each method, we will focus on some typical examples of monitoring by continuous automatic in-situ measurements that we have set up.
