On November 12, 2023, a tragic incident unfolded in the Uttarkashi district of Uttarakhand, India, as a portion of the Silkyara Bend - Barkot tunnel, under construction, collapsed, trapping 41 workers inside. The collapse occurred at around 5:30 AM IST, sending shockwaves through the nation and igniting a massive rescue operation called ‘Operation Zindagi’. The workers have been trapped under the collapsed tunnel for 17 days now. Meanwhile, the Uttarakhand government has also constituted a six-member expert committee to investigate the cause of the tunnel collapse.

The Silkyara Bend-Barkot tunnel, a crucial component of the Char Dham all-weather road project, was being constructed by Navayuga Engineering Construction Limited (NECL). This tunnel, located at the Yamunotri end of National Highway 134, aimed to provide a shorter and more accessible route to one of Hinduism's revered pilgrimage sites. With a planned length of 4.5 kilometres, the tunnel was expected to reduce travel time significantly, enhancing connectivity and pilgrimage experiences.

Operation Zindagi is a massive rescue operation launched by the state government to save 41 workers trapped for 17 days now in the Silkyara Bend - Barkot tunnel collapse in Uttarakhand, India. The operation has deployed two tunnel-boring machines.
Three lifelines were drilled during the operation to sustain the trapped workers amidst the Uttarakhand tunnel collapse: an oxygen pipe, a dry food pipe, and a wider pipe for hot meals and camera insertion.

The 6-inch (15 cm)-wide pipe, the most versatile of the three, delivered hot meals, offering a comforting dose of nourishment amidst challenging circumstances. Additionally, this pipe enabled the insertion of an endoscopic camera, allowing rescuers to monitor the workers' condition and establish visual communication.
On November 25, 2023, the rescue operations faced a setback after the auger machine broke. As per reports, the rescue team had drilled through the 60-metre stretch of the rubble of the collapsed tunnel. On November 27, 2023, six rat-hole miners from Delhi and Madhya Pradesh were called in to work manually to dig through the debris.
Uttarakhand tunnel rescue operation is being carried out by the NDRF, SDRF, Indian Army, and other state and central agencies. IAS officer Neeraj Khairwal has been tasked as the Nodal officer of the Silkyara tunnel collapse. Chris Cooper, a micro-tunneling expert has also arrived. Syed Ata Hasnain, retired Lieutenant General of the Indian Army and member of the NDMA team is overseeing the rescue operations of the National Disaster Management Authority. Arnold Dix, a scientific researcher and underground tunnelling expert is also present at the scene.
