Uttarkashi (Uttarakhand) [India]: Rescuers have managed to drill through 24 metres into the rubble inside the Silkyara Tunnel, and are getting closer to 40 labourers who have been trapped inside, following the collapse of the under-construction tunnel for six days now.

Of the estimated 60 metres they have to cover to reach the trapped workers, rescuers had worked overnight using a new auger drill machine brought in from Delhi and managed to drill upto a depth of 25 metre through the debris after which the machine hit a metal part inside.
Officials said that efforts being made to cut through it using a gas cutter and drilling work was currently halted.
Rescue teams are hoping to evacuate the trapped workers by inserting 800m and 900 m steel pipes to create an escape route out of the tunnel. National Disaster Response Force personnel (NDRF), who are at the site also carried out a mock drill of a “possible evacuation through the 900mm wide steel pipes”.
“The American auger is a highly advanced drilling machine. Four pipes have been already inserted and welding for the fifth one is underway. We will rescue all the labourers,” Uttarkashi Superintendant of Police Arpan Yadavanshi said this morning.
The police official stated that all technical workers were working round-the-clock to rescue the stranded labourers.
“SDRF, NDRF, Police, medical workers, fire service, everyone is working in co-ordination to safely rescue the labourers. We are also conducting a mock drill to provide medical aid to them as soon as they are rescued,” SP Yadavanshi said.
