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.

Nepal PM calls for global response to rising Himalayan climate risks

Published

on

Kathmandu, Sep 2: Nepal Prime Minister Balendra Shah on Wednesday called for stronger international attention to growing climate-related risks in the Himalayan region as the death toll from devastating floods in the Bhotekoshi River crossed 1,100.

Addressing the House of Representatives, Shah said Nepal must highlight more forcefully the disasters it is facing due to climate change.

At least 1,114 bodies swept away by last week’s floods had been recovered by 9 am Wednesday, according to the National Disaster Risk Reduction and Management Authority (NDRRMA). Around 3,916 people remain out of contact.

Experts said an avalanche blocked the Lengde Khola, a tributary of the Bhotekoshi River near the Nepal-China border. The accumulated water later breached the natural barrier, triggering a massive flood that swept downstream towards the Trishuli River and devastated settlements and infrastructure.

Shah said the disaster had raised questions about how such an event occurred and what it meant for Nepal’s future.

“The huge disaster, whose impacts of climate change we have suddenly experienced, has kept us working around the clock to manage the damage. At the same time, another profound question has arisen in our minds: How did this disaster come upon us?” he said.

Referring to expert assessments, Shah said the incident was a serious warning that climate change was increasing risks in the Himalayan region.

“We must make the international community aware of the disasters we are experiencing as a result of climate change. Climate change is a global challenge. Its impacts and efforts to mitigate and manage them are the shared responsibility of the global community,” he said.

Shah also defended the government’s response to questions over whether timely warnings were issued to the public.

“As soon as we received information that the flood was approaching, our security personnel were deployed to alert residents. However, they themselves went missing during the operation,” he said.

Some media reports had suggested that the Nepali government was reluctant to accept international assistance for the rescue and relief of flood victims.

Seven days after the disaster, Shah told Parliament that the government had never adopted a policy of refusing international assistance during major disasters.

“We had been coordinating with international countries from the very beginning to seek assistance as needed in the affected areas. We had also tried to expedite the process of receiving international assistance,” Shah said.

“Our friendly neighbours, India and China, had already sent technical experts. They had been conducting reconnaissance from the very first day, including on the first and second days,” he said.

Shah told Parliament that the flood was accompanied by huge amounts of mud and debris, making it impossible for even foreign rescue teams that arrived at the outset to land at the affected sites.

“After conducting reconnaissance and monitoring to determine whether they could reach the sites, they concluded that it was not immediately possible to land there. The Indian and Chinese technicians, along with Nepali technicians and the Army, could reach the sites only after conditions became suitable for them to do so,” Shah said. “This was an exceptional situation.”

The Prime Minister also said excavators could not be deployed initially because of the heavy mud and debris.

“There was no stable ground not only for excavators but also for personnel from the Army and Armed Police Force. That is why they tried to reach the sites by crawling as much as possible,” Shah said.“Rescue operations began only after stable ground was available for excavators and suitable places were available for helicopters to land.”

Shah also thanked countries and international organisations for supporting Nepal’s flood response, naming India, China, the US, the UK, Australia, Japan, South Korea, the UAE, Qatar, Switzerland, Singapore, Pakistan, Sri Lanka and Bangladesh, as well as the Asian Development Bank, World Bank, European Union and United Nations.

Several other friendly countries and international organisations have also pledged further assistance, he said.

Meanwhile, the whereabouts of many people reported missing from 11 flood-affected hydropower projects remain unknown, as rescue efforts have so far produced limited results.

According to the Independent Power Producers’ Association, Nepal (IPPAN), the status of 983 people associated with 11 hydropower projects along the Bhotekoshi and Trishuli river corridors in Rasuwa and Nuwakot remains unknown.

Nepali Army personnel, along with Indian and Chinese tunnel rescue teams, have been making efforts to reach deep inside tunnels at several hydropower projects to determine whether those reported missing can be located.

The private sector’s representative body for power developers said Tuesday evening that rescue efforts were continuing at projects including the Upper Trishuli 3A Hydropower Project (60 MW), Chilime Hydropower Project (22 MW), Langtang Khola Hydropower Project (20 MW), Trishuli 3B Hydropower Project (37 MW) and Upper Trishuli-1 Hydropower Project (216 MW).

At the Upper Trishuli-1 Hydropower Project, 1,433 people were working when the floods struck, according to IPPAN.

Of them, 876 have either been rescued or have made contact.

Those still unaccounted for include 15 employees of the project company, 78 employees of EPC (Engineering, Procurement and Construction) contractor Doosan, 94 employees of Andritz Hydro, seven employees of consultant — the Joint Venture of Lahmeyer International GmbH and Jade Consult Pvt. Ltd, and 385 workers employed by civil subcontractor PowerChina, according to IPPAN.

The whereabouts of 91 people reported missing from the Rasuwagadhi Hydropower Project (111 MW) remained unknown as of Tuesday.

A Nepali Army-led team conducted an on-site inspection on Monday and returned after reporting that it had found no one inside the powerhouse tunnel.
