Prueba de Radiolocalización y Radioenlace entre Candanchú y el Túnel Ferroviario Internacional de Canfránc (Huesca)

Abstract

A new device for underground radiolocation and radio conection was tested betweeen the railway tunnel of Canfranc and the sky ressort of Candanchu. The results provide a radiolocation through 500 m. of limestone and wet shale, and a radioconection through 890 m. of karstified limestones. Giving the relation between the electrical conductivity of the rock and the attenuation of the signal, the results suggest that the device could be used as a geophysical tool
