Vertical Drilling Begins At Uttarkashi Tunnel Collapse Site | Read

The 41 workers trapped in an Uttarakhand tunnel for 15 days were dealt another blow when officials said that the giant drill working on their rescue has collapsed. Indian Army has joined the operation and been tasked with the manual drilling. The blades of the auger machine got stuck in the debris as it was drilling through the rubble of the collapsed Silkyara tunnel. The heavy drill brought in from America to break through nearly 60 meters of debris was damaged on Friday and is now being pulled out, officials said, adding the last 10-15 metres would have to be broken with hand-held power tools.
