Uttarkashi: Senior authorities stated on Tuesday that provided there are no hard rock obstructions the government's primary method of horizontal drilling could free all 41 trapped workers from the Silkyara tunnel in Uttarkashi in less than three days.
The officials also said that the process could take longer in case the horizontal drilling does not work out and some other methods are adopted to rescue the workers who have been trapped in the tunnel since November 12.
The officials said the government has undertaken a five-option action plan to rescue the workers.
Briefing reporters on the rescue efforts, Anurag Jain, Secretary of the Ministry of Road Transport and Highways, said that under the current circumstances “vertical drilling is the second best option”.
