Recovery teams have retrieved 22 bodies from a collapsed construction tunnel at an NHPC site in Namchi, Sikkim [1].

The incident highlights the extreme risks associated with tunneling in the volatile terrain of the Himalayas, where gas pockets can trigger sudden disasters.

Authorities said a methane gas explosion caused the structural failure within the tunnel [1]. The recovery effort intensified recently, with rescue crews finding nine bodies overnight [1].

Despite the high death toll, operations remain active as teams search for three workers who are still missing [2]. The site is managed by the National Hydroelectric Power Corporation (NHPC), which is overseeing the construction project in the Namchi region [1].

Emergency responders are working to clear debris and stabilize the area to reach the remaining trapped individuals. The sudden nature of the collapse has complicated the recovery process, leaving crews to navigate unstable rock and suspected gas leaks.

Local officials said they have not yet released a final timeline for the completion of the recovery phase. The focus remains on the three missing laborers as teams employ specialized equipment to penetrate the collapsed sections of the tunnel [2].

“22 bodies recovered”

This disaster underscores the geological instability of the Sikkim region and the critical need for advanced gas detection systems in hydroelectric infrastructure projects. The loss of 22 lives suggests a significant failure in safety protocols or an unforeseen geological anomaly that bypassed existing precautions.
