U’khand tunnel: Rat-hole miners arrive for manual horizontal drilling
Vertical drilling from the top of the Silkyara tunnel, where 41 workers have been trapped for the last 15 days, progressed to 31 metres on Monday as a team of rat-hole miners arrived at the site to start manual drilling horizontally through the rubble.
Vertical and manual horizontal drilling are the two methods on which rescue efforts are being focused at the moment. Work on the other options, such as horizontal drilling from the Barkot end of the tunnel is also underway.
