Safer tunneling can be achieved by performing the appropriate measures required for ground stability, observing tunnel face situations and grasping geological conditions precisely in parallel with excavating. We developed the new “Tunnel Face Observation Record System” contributing to efficient tunnelling and highly information-orientd tunnelling. In the system, filming tunnel face with a video camera or a digital still camera, the digital information is transmitted with the SS radio to a site office. The digital information is converted into a list of face observing record with a personal computer. In this paper, we report about the abstract of “Tunnel Face Observation Record System” and the results of radio transmission experiment on reliability of radio telecommunications.
