All 41 Workers Freed After Silkyara Tunnel Collapse
- A section of the Silkyara Bend-Barkot tunnel in Uttarkashi, Uttarakhand (Char Dham project, NH 134) collapsed around 05:30 IST on 12 November 2023, trapping 41 workers behind a blockage about 60 m long[2][3]
- Rescue effort (Operation Zindagi) involved NDRF, SDRF, NHIDCL, the Army, BRO, ITBP, the Air Force and others, plus Australian expert Arnold Dix; augers failed, one breaking 47 m in on 25 November, while vertical drilling also began[2][3]
- Pipes supplied oxygen and food; on 28 November rat-hole miners broke through by hand and pushed a pipe through, and all 41 were rescued around 20:50 IST after 16-17 days; 40 were declared fit by 1 December[2][3]
- The weak rock (meta-siltstone and phyllites near the Main Central Thrust) and lack of escape shafts were blamed; NHAI ordered a safety audit of 29 tunnels, and the probe found negligence by NHIDCL, the builder (Navayuga) and the supervising engineer[2]

WebFetch could not retrieve the NDRF's own operations page (certificate error); India's National Disaster Response Force is the lead agency credited with the rescue, so its title is consistent with the pin's claim, though the page's content could not be verified directly.
