Hyderabad:Rescue operations for the eight trapped persons faced several challenges in Telangana's Srisailam Left Bank Canal (SLBC) tunnel on the second day on Sunday. Massive mud and debris piled up at a height of 15 metres for 100 metres inside the tunnel at the 14th-kilometre collapse spot, which significantly hampered the work of the rescue teams.
The debris has to be removed for another 50 metres to reach the spot where the eight persons, including two engineers, were trapped, said rescue teams consisting of experts of the National Disaster Response Force (NDRF), SDRF, Singareni Rescue Team, Hydraa and Fire Department. NDRF Deputy Commandant Sukhendu Datta said that the eight trapped persons were yet to be traced.
High-capacity pumping sets, cranes and bulldozers are being used by the rescue teams to remove the debris and push forward towards the collapse section. On the other hand, a team from the Indian Navy would also join the rescue operations tonight.
Meanwhile, Irrigation Minister N Uttam Kumar Reddy said that the government would make every effort to bring back the trapped workers alive and that they were also exploring the option of reaching the collapse spot from above the tunnel.
A three-meter section of the roof of an under-construction stretch of the SLBC tunnel collapsed at the 14 km mark near Domalapenta in Nagarkurnool district, Telangana on Saturday. Seven of the eight trapped inside the tunnel have been identified as Gurjeet Singh (Punjab), Sannit Singh (Jammu and Kashmir), Srinivasulu, Manoj Rubena (Uttar Pradesh), Sandeep, Santosh, and Jatka Heeran (Jharkhand). The collapse occurred just four days after construction work had resumed following a long hiatus.
With the rescue operations continuing on the second day, the rescue team has not yet been able to confirm the exact 'location of the trapped workers.' NDRF Deputy Commandant Sukhendu Datta said that the force has covered around 13.5 kilometres inside the tunnel, primarily using locomotives and conveyor belts.
"Yesterday around 10 PM we went inside to check what the situation is like. The locomotives were used to go inside the tunnel. From the gate of the tunnel, we covered around 13.5 km in total. We covered 11 km by train and then we covered the rest of 2 km by conveyor belt and by walking,' said Dutta.
The official added that the last 200 meters of the collapsed section is completely blocked by debris, making it difficult to confirm the condition or exact location of the trapped workers.
"We had reached the end of the Tunnel Boring Machine, TBM. We shouted and tried to get a reply from the trapped workers but unfortunately, we could not know anything because there was a patch of around 200 meters which is filled with debris. Till the debris is cleared we cannot know the exact location of the victims," the official said.
The response force is currently working to remove the accumulated water inside the tunnel. "The patch between the 11 to 13 km is filled with water, so right now we are in the process of removing the water. When that is done, we will start the rescue operations," he added.
