DEHRADUN: India has sought advice from the Thai company that rescued children from a flooded cave in 2018 as it races to save 40 men trapped in a road tunnel, officials said on Wednesday.
Excavators have been removing debris since Sunday morning from the site in the Himalayan state of Uttarakhand to create an escape tunnel for the workers, all of whom are still alive.
Officials have "contacted the Thai company which rescued the children trapped in the cave", the state government's department of public relations said in a statement.
The statement was referring to the dramatic operation to rescue 12 boys from a junior football team and their coach who were trapped for more than two weeks in the Tham Luang cave complex.
Authorities have also asked for help from engineering experts in soil and rock mechanics at the Norwegian Geotechnical Institute as frantic efforts to free the men stretched into a fourth day.
Rescuers said on Wednesday they had sent medicine to the 40 men, trapped since the road tunnel they were building collapsed on Sunday.
"After consultation with doctors, medicine has been sent to the workers through pipes," police officer Prashant Kumar said from the site. "Contact is being maintained with the workers."
No details were given about the condition of the men or how many of them were sick.
But as rescue teams removed the vast piles of rubble, more fell from the broken roof of the tunnel and two labourers working to remove the debris were injured overnight on Tuesday, Kumar said.
The pace of drilling was "slow because of natural causes", but efforts were being made on a "war footing", Uttarakhand state police chief Ashok Kumar said in a statement on Wednesday.
The air force on Wednesday flew in a second drilling machine on a C-130 Hercules military plane on Wednesday to "speed up rescue work" after the first one broke down, he said.
Engineers are using heavy machinery to drive a steel pipe about 90 centimetres wide through the debris, wide enough for the trapped men to squeeze through.
"We should keep our patience and trust," Ashok Kumar said. "I am sure that we will rescue all the labourers."
The 4.5-kilometre tunnel was being constructed between the towns of Silkyara and Dandalgaon to connect Uttarkashi and Yamunotri, two of the holiest Hindu shrines. — AFP
