Detection and characterization of underground cavities using high resolution seismic reflection (HRSR)

Abstract : Old Underground mining works are subjected to risks of collapse of which the assessment is a complex process. In the case of inaccessible Underground mines, the difficult task for the risk assessment is to classify the already collapsed zones (no further risk) from still stable structures which may collapse in the future. The knowledge of the characteristics of the Underground cavities and hosting rock mass can provide relevant information. However, accurate Underground cavities detection and characterisation based on geophysical techniques are still a scientific challenge in the subsoil prospecting domain. Among these techniques, the high resolution seismic reflection is the most successful in the frame of Underground cavities detection. The study presented in this paper, is a part of an extended research program aiming at prediction and controlling ground motions induced by Underground cavities.
