Abstract

The purpose of this study is to implement a new technique for monitoring the abandoned mines subjected to flooding: it consists of a hydroacoustic monitoring (sensor placed in water filling the mining cavity) in a broad frequency bandwidth (30 Hz-1 80 kHz). GISOS, a French scientific interest group concerned with the impact and the safety of the underground works in the field of the post-mining, aims amongst other at understanding the phenomena occurring in the old mining cavities in order to forecast their evolution. A very significant research effort is put on the monitoring methods for assessing degradation of the mining works, as they directly threaten the infrastructures located on the ground surface. One of the parameters, which have a significant role in the stability of the underground works, is water.
