In an effort to step up the rescue operations in Uttarkashi, a rat hole mining technique will be used through manual drilling to remove the debris inside the pipe on the 16th day of continued rescue efforts in Silkyara tunnel, according to officials.
As the Uttarkashi tunnel rescue operation enters day 16 on Monday, prayers are granted across the nation for the safe rescue of the 41 trapped soldiers.
The vertical drilling from the top of the hill makes swift progress as 31 metres of drilling work has been completed so far out of the 86 metres needed to reach the 41 trapped workers in the Silkyara tunnel, as per officials.
National Highways and Infrastructure Development Corporation Limited (NHIDCL) Managing Director Mahmood Ahmad on Sunday informed that a total of 19.2 meters of vertical drilling has been completed at Uttarkashi's tunnel where 41 workers remained trapped.
