Uttarkashi tunnel collapse: Drilling halted due to technical glitch
New Delhi: As the rescue mission to extract 41 trapped workers through the debris at the Silkyara tunnel in Uttrakhand entered its 13th day, the National Disaster Management Authority (NDMA) on Friday said no further progress has been made since Thursday in the drilling process.
However, a ground penetrating radar (GPR) indicated that there are no metal hurdles up to five metres ahead of the passage bored through the debris of the tunnel’s collapsed portion. The GPR reading was a tough task as it required the team to enter the pushed pipe of 46 meters.
