Telangana tunnel collapse: Rescue teams re-draw strategy

Published

on

Hyderabad, Feb 25: Rescue teams involved in the intensive operation to pull out eight persons trapped in an under-construction tunnel which collapsed in Telangana’s Nagarkurnool district for three days are re-drawing the strategy to move forward in the last stretch of 40-50 metres.

Facing several hurdles, the authorities have roped in experts from the Geological Survey of India (GSI), the National Geographical Research Institute (NGRI), and the National Remote Sensing Agency (NRSA) to assess the situation and suggest the way forward for rescue operations.

Multiple teams of the National Disaster Response Force (NDRF), Army, Larsen and Toubro (L&T) and various agencies are moving cautiously as the stability of the tunnel has to be taken into consideration while undertaking any excavation work.

While continuing dewatering, the rescue teams were waiting for the experts to suggest the next step.

Various agencies including the Army, Navy, SDRF, National Highway Infrastructure Development Corporation, and Singareni Collieries Company Limited have mapped out the tunnel operation. They prepared a detailed diagram to help prepare a rescue strategy to locate and reach eight trapped men.

Officials said the conveyor belt used to bring back debris from the tunnel after excavation was not working.

Minister for Roads and Buildings Komatireddy Venkat Reddy said the efforts were on to repair the belt.

Deployment of advanced equipment like endoscopic and robotic cameras to trace the trapped men has not yielded results. According to officials, the robotic camera is not working.

Tunnel Boring Machine (TBM) broke into two after a portion of the tunnel roof collapsed on the morning of February 22.

The tail unit of TBM was found 50 metres before the end of the 14 km long tunnel. The head portion of the tunnel has a safe container for workers to take shelter in an emergency. It was not known if the trapped men could enter the container when the roof collapsed and water seepage became intensive.

The drone was also not accessible after the TBM tail unit. The 50-metre area is filled with sediments and debris hampering further movement of the rescue teams for the last 24 hours.

The tunnel map prepared by the rescue teams shows that the loco track is accessible up to 12 km though the track is available for a length of 13.5 km.

There is no water stagnation in the tunnel till 10.7 km point. The teams found 1.5 feet water at 10.95 km There is 2 to 2.5 feet water at 11.30 km.

The NDRF team has also deployed a trained sniffer dog for the rescue operation but the same could not be pressed into service due to slush.

A team of expert rat miners, known for a successful rescue operation in the Silkyara Bend-Barkot tunnel in Uttarakhand in 2023, has arrived, but their services have not yet been used. In Uttarakhand, the team rescued 41 workers who were trapped inside the tunnel for 17 days.

The team members, however, said that the situation in Telangana is different. In the Uttarakhand tunnel, it was rock and they used hand tools to reach trapped workers through small pits. However, the SLBC tunnel is filled with water and mud.

Deputy Chief Minister Mallu Bhatti Vikramarka, Irrigation Minister Uttam Kumar Reddy, Roads and Buildings Minister Komatireddy Venkat Reddy and Tourism Minister Jupally visited the tunnel and reviewed the rescue operations with various agencies.

Uttam Kumar Reddy said he invited Harpal Singh, former engineer-in-chief of Border Road Organisation to share his expertise and knowledge for the rescue operation. The minister quoted Harpal Singh as saying he had never seen such a complicated tunnel accident.

Two workers were injured and eight others were trapped when a portion of the tunnel being dug as part of SLBC collapsed near Domalapenta.

A total of 50 persons were working on the left-side tunnel when the roof collapsed for three metres. The accident occurred at the 14th km point.

While 42 workers came out of the tunnel, the remaining eight were trapped. Those trapped include two engineers and two machine operators.

The trapped men are from Jharkhand, Uttar Pradesh, Punjab and Jammu and Kashmir.

Project manager Manoj Kumar (Uttar Pradesh), Machine engineer Srinivas (Uttar Pradesh) and machine operators Sunny Singh (J&K) and Gurpreet Singh (Punjab) are among those trapped.

The four workers from Jharkhand are Sandeep Sahu, Santosh Sahu, Anju Sahu and Jagta Khes.

Air India plane crash: 144 victims identified by DNA tests, recovery efforts intensify

Published

on

Ahmedabad, June 17: Four days after the devastating crash of Air India flight AI-171 en route from Ahmedabad to London, authorities have confirmed that 144 DNA samples have been successfully matched as of noon Tuesday, according to Gujarat Minister of State for Home, Harsh Sanghavi.

The identification process is being led by a combined team from the State Forensic Science Laboratory (FSL) and the National Forensic Sciences University, working around the clock to bring clarity to grieving families.

“This is a highly sensitive and emotional task. Every match is not just a technical confirmation, but a step toward giving closure to families waiting in anguish,” an official from the forensic unit said.

Emergency response teams remain stationed at the crash site in Meghaninagar, where investigators continue to recover personal belongings and body fragments amidst the wreckage.

Authorities have stated that all efforts are being made to ensure the dignity of the deceased and transparency in communication with the victims’ relatives.

Tata Group, which re-acquired Air India in 2022, has announced an ex gratia payment of Rs one crore to the families of each of the deceased from the AI‑171 crash near Ahmedabad. In addition, Air India has immediately released an interim relief payout of Rs 25 lakh per family — and to the lone survivor — to cover urgent needs.

The group will also cover all medical expenses for the injured and pledged financial support for rebuilding a damaged hostel at BJ Medical College. Chairman N. Chandrasekaran described it as “one of the darkest days in the Tata Group’s history.”

As of June 17, rescue and recovery efforts at the Ahmedabad crash site of Air India flight AI-171 remain intense and deeply coordinated. Over 300 firefighters, supported by 60 fire vehicles and 20 water bowsers from Ahmedabad, Gandhinagar, Vadodara, ONGC, and other nearby agencies, continue to clear debris and extinguish smouldering wreckage.

On the ground, three NDRF teams, 150 CRPF officers, Indian Army personnel, and teams from the CISF, BSF, and Western Railway Disaster Management are conducting systematic searches for remains and missing belongings.

Specialised sniffer dogs are aiding in the recovery of human remains, while Ahmedabad Police, responding to disturbing reports, have deployed animal rescue teams to safely relocate stray dogs scavenging at the crash site.

Ahmedabad plane crash: Probe intensifies after 2nd black box recovered

Published

on

Ahmedabad, June 16: After the second black box, which is a critical component in determining the cause of the crash, was recovered, the investigators have intensified the probe in the Air India crash case.

The Cockpit Voice Recorder (CVR), commonly referred to as the second black box, was retrieved from the cockpit section of the wreckage.

This comes days after the Flight Data Recorder (FDR) was recovered from the tail end of the aircraft. The Cockpit Voice Recorder (CVR) captures all audio inside the cockpit, including conversations between pilots, radio transmissions, alarm sounds, and any background noise in the final moments before a crash.

It is a crucial tool for investigators, as it helps reconstruct the crew’s decision-making, identify possible human errors or mechanical warnings, and determine the sequence of events that led to an aviation incident.

Officials from the Aircraft Accident Investigation Bureau (AAIB) confirmed the findings, noting that both devices are in the process of being analysed. The CVR is expected to provide crucial insights into the final moments of the flight, including pilot communication and cockpit sounds, which may help investigators piece together the chain of events leading up to the tragedy.

The recovery was also acknowledged by P.K. Mishra, Principal Secretary to Prime Minister Narendra Modi, who visited the crash site on Sunday. During his visit, he reviewed ongoing investigation efforts and later went to the Civil Hospital, where injured passengers and local residents are being treated.

The death toll from the catastrophic Air India crash in Meghaninagar has risen to 270, officials have said. Among the deceased are 241 passengers who were on board the ill-fated flight, as well as several others who were present in nearby hostels, mess halls, and the surrounding residential area when the aircraft went down.

Meanwhile, the Gujarat government has declared a one-day state mourning on Monday in the state as a mark of respect to former Chief Minister Vijay Rupani, who lost his life in the Air India plane crash in Ahmedabad on June 12. All official functions and celebrations will remain suspended during the mourning period, and the national flag will be flown at half-mast across government buildings.

Over 1,000 shops gutted in devastating fire at Kolkata’s Khidirpur

Published

on

Kolkata, June 16: A devastating fire broke out at a busy marketplace in the Khidirpur area of South Kolkata, West Bengal, early Monday morning, gutting over 1,300 shops. No casualties have been reported so far.

A total of 20 fire tenders are already on the spot trying to bring the fire under control. An official of the state fire services department present at the spot said the fire had been brought under control to a great extent and to the point that it would not spread further.

“However, the problem that is now being faced by the fire-fighters is identifying the hidden ‘fire pockets’ and bringing them under control, following which it could be said that the situation is totally under control. After the task of identifying and deactivating the hidden ‘fire-pockets’ is over, the cooling process will start,” the fire department official said.

However, the local people have alleged that the fire would not have taken the devastating shape had the fire tenders reached the spot in time. The state fire services minister, Sujit Bose, who rushed to the place in the morning, however, denied the allegations.

“This is a baseless allegation. Since the requirement of fire tenders in this case was more, these vehicles reached the spot from multiple locations like Watganj and Garden Reach. The firefighters are risking their lives to bring the situation under control. At the same time, the owners of the shops were also negligent in adopting fire safety norms. I am not trying to blame anybody. But we will be investigating the matter,” Bose said.

However, the local traders, whose shops were gutted, claim otherwise. “First, the fire tenders reached late. Secondly, the vehicles that reached first did not have enough water. Thereafter, arrangements were made to pump water from the nearby flowing stream of the River Ganges. All these delayed the process to a great extent,” a local trader said.

It is learned that the fire was spotted at around 2 a.m. Besides informing the central control line of the state fire services department, the local people also started the initial task of firefighting. However, because of the congested area where the marketplace was located, the fire started spreading rapidly, and the entire market area came under the grip of fire within a very short period.

“Fortunately, the fire broke out at a time when there were hardly any people in the market area. Had the fire broken out in the daytime, there could have been several casualties. However, we fear that the value of the loss of property and assets because of the fire is huge,” said the fire department official.
