Robot deployed to help rescue teams in SLBC tunnel in Telangana
Eight people, including engineers and labourers, were trapped under the debris when a portion of the roof collapsed at the SLBC tunnel in Telangana’s Nagarkurnool district on February 22
Hyderabad: The Telangana government on Tuesday deployed a robot to assist the ongoing rescue operations for tracing the remaining seven persons trapped under the debris in the Srisailam Left Bank Canal (SLBC) tunnel in Nagarkurnool district, which partially collapsed on February 22.
An official statement said on the 18th day of rescue operations, representatives from Hyderabad-based Anvi Robotics, Vijay and Akshay, entered the tunnel via a loco train on Tuesday morning, along with the robot, equipped with an AI-based camera system.
Eight people, including engineers and labourers, were trapped in the debris. The rescue agencies managed to retrieve the body of a tunnel boring machine operator, identified as Gurpreet Singh, a resident of Cheema Kalan village of Tarn Taran district of Punjab, on Sunday.
According to officials, Singh’s body was located with the help of cadaver dogs brought from Kerala and was extricated after strenuous efforts of nearly 48 hours. Officials said that cadaver dogs on Monday identified two more possible locations of the bodies about 16 metres away from the tunnel boring machine.
Officials said that robotic assistance is being utilised to ensure that no human casualties occur during the rescue operations.
They said the representatives of Anvi Robotics have also set up a communication system at the nearby office to facilitate coordination.
“Additionally, necessary rescue equipment and safety harnesses were provided, and two human remains detection dogs (HRDDs), also known as cadaver dogs, were once again sent to the accident site for further investigation,” the statement said.
Along with Anvi Robotics team, as many as 110 rescue personnel from National Disaster Response Force (NDRF), State Disaster Response Force (SDRF), Singareni Collieries, South Central Railways, Rat Miners and a few other agencies went inside the tunnel in the morning to intensify the efforts to trace those still trapped under the debris.
Special chief secretary (disaster management) Arvind Kumar and Nagar Kurnool district collector Badavath Santosh conducted a review meeting on Tuesday at the SLBC Tunnel office with senior officials regarding the ongoing rescue operations.
The statement said the officials extensively deliberated on the procedures to be followed in rescue operations, the use of robotics and mechanical equipment, the process of debris removal, and safety measures. They also provided necessary directives to expedite the rescue operations.
“Excavation is currently underway at these sites. However, Singareni miners have noted that the area is delicate. As the tunnel water is being drained, the remaining debris has hardened like concrete, making excavation difficult,” an official explained to the special chief secretary.
To prevent soil collapses onto the rescue teams, logs have been brought in to provide structural support during the excavation process. Approximately 15 feet of soil needs to be excavated at the three locations identified by the cadaver dogs, officials said.
