Estudio mediante técnicas de Geo-radar del subsuelo y galerías de la mina de sal abandonada de Cardona para su habilitación como intinerario cultural

The opening of abandoned salt mines whit the idea of prepare cultural routes requires the use of hard machinery in abandoned places. The erosion caused by salt disolutions damage the mine structure, being dangerous for restoration and visiting purposes. Planed jobs were the opening of a new gallery to prepare a round route and restoring the part of the salt mine that will be open to the public. Ground penetrating measurements have been used, first to locate the position and depth of underground scour holes and subsurface voids in the ground and in the solid salt mountain, and second, to study the vault and gables end in the salt mine galleries. Three antennas were used in his job, with WO MHz, 300 MHz and 500 MHz center frecuencies.. Radar data has locate holes in the first meters under the floor of the mine galleries and into the contact between the salt mountain and the cover materials. The analisys of the anomalies also shows scour holes in to the slag heap caused by the flowing water which eroses the soft materials. These areas are not safety places for mining jobs. This work try to provide safety measurements to the salt mine workers and try to assists to the tourist mine maintenance planning
