Surveillance des risques d'effondrement dans l'après-mine, besoins, méthodes : apport de la microsismique

Abstract : During the exploitation, the stability of the underground mining works mainly directed towards the safety of the staff and the safeguard of the mine, were practised with methods adapted to accessible and maintained buildings. Following the closure of the mines, these conditions not being more assured and the objectives of public safety resolutely turned towards the safeguard the people and the overlying structures (such as urbanised areas and all kind of infrastructures), result in remotely seeking applicable total methods and from surface. Among those, we develop the typical example of the microsismicity which, before being applied to the monitoring of the risks of mining collapse had to answer a precise schedule of conditions to be qualified then validated. An example of its use successfully for the moni'.oring of the pillar of Nondkeil (Ottange, 57) is proposed.
