Rescuers have to drill down 86 metres from above to reach the trapped workers. Vertical drilling has gone up to 19.2 metres so far, National Highways & Infrastructure Development Corporation Limited (NHIDCL) MD Mahmood Ahmed said at a press briefing.
“The exercise is going on smoothly and if it goes like this without facing obstructions, we can hope to finish it in four days by November 30,” he said.
The National Disaster Management Authority (NDMA) said that work is on to retrieve broken parts of the auger machine while vertical drilling has started to bring out 41 workers trapped in Silkyara tunnel in Uttarkashi for two weeks.
