Hyderabad: The rescue operation in Telangana’s Nagarkurnool district continues from last 60 hours where eight trapped workers from an under-construction tunnel, a part of which collapsed on Saturday.
Earlier, a portion of the Srisailam Left Bank Canal (SLBC) tunnel collapsed, the fate of eight men, including two engineers and two machine operators, was not known.
Multiple teams from the National Disaster Response Force (NDRF), the Army, and other agencies continued their efforts to dewater and desilt the tunnel close to the point where a portion of the roof had collapsed.
Two teams of construction major Larsen & Toubro with advanced equipment on Monday joined the operation. The teams deployed endoscopic and robotic cameras to capture any movements of trapped men.
The same equipment for rescue operations after the Silkyara Bend-Barkot tunnel collapse in Uttarakhand, where 41 workers trapped inside were rescued after 17 days in 2023.
Rat miners, who were part of the Silkyara rescue operation, were assisting the NDRF, Army, and others in the rescue effort.
Nagarkurnool district Collector Badavath Santosh said the rescue teams had to cover a distance of another 40 metres to reach the point where the roof had collapsed. This stretch of the tunnel is filled with muck, making further advance of the rescue operations difficult.
The tunnel remained flooded with water for about two kilometres, making the rescue task more challenging for more than 300 rescue workers. Rescue teams deployed heavy motors for dewatering.
The NDRF, the Army, the Singareni Collieries Company Ltd (SCCL), and the Hyderabad Disaster Response and Asset Protection Agency (HYDRAA) were making intensive efforts to dewater and desilt the tunnel.
