India bid to free 41 trapped workers enters third week

SILKYARA TUNNEL, India - India’s military brought in specialised equipment on Nov 26 as efforts to free

41 trapped workers

entered a third week, with digging ongoing in three directions after repeated setbacks to the operation.

The Indian air force said it was “responding with alacrity”, as it flew in its third load to a rescue operation since the partial collapse of the under-construction Silkyara road tunnel on Nov 12 in the Himalayan state of Uttarakhand.

Rescue officials said they called for a superheated plasma cutter to be brought to the remote mountain location, after engineers driving a metal pipe horizontally through 57m of rock and concrete ran into metal girders and construction vehicles buried in the earth.

A giant earth-boring machine snapped just 9m from breaking through.

The plasma cutter will be used to remove the broken giant earth-boring drill and metal blocking the horizontal route, before digging will continue by hand.

Vertical shaft

Thick metal girders in the rubble are blocking the route, and using conventional oxyacetylene cutters to clear them is tricky from inside the confined pipe, only wide enough for a man to crawl through.

The air force said the “critical” kit came from the country’s Defence Research and Development Organisation, the government’s defence technology research arm, without giving further details.

Uttarakhand Chief Minister Pushkar Singh Dhami said on Nov 25 that vertical drilling had begun to dig 89m downwards, a risky route above the men in an area that has already suffered a collapse.

Work has also begun from the far side of the road tunnel, a much longer third route estimated to be around 480m.

Mr Dhami visited the home of one of the trapped workers on Nov 26 and apprised the family of the efforts being made for their rescue.

“We are working with full force to get all the workers out safely,” he said in a post on social media.

The workers were seen alive for the first time

on Nov 21, peering into the lens of an endoscopic camera sent by rescuers down a thin pipe through which air, food, water and electricity are being delivered.

Mr Dhami said the men are in “good spirits”, with a basic telephone exchange set up so that families of the trapped men – many of whom are migrant workers from poor families from far across India – could call in to speak to them.

‘Difficult operation’

Efforts have been painfully slow, complicated by falling debris and

repeated breakdowns of drilling machines

.

Hopes that the team was on the verge of a breakthrough on Nov 22 were dashed, with a government statement warning of the “challenging Himalayan terrain”.

Mr Indrajeet Kumar told The Times of India he felt “like crying” when he spoke to his brother Vishwajeet, who is among the trapped workers. The brother questioned why they were still stuck after reports that they “would be out soon”.

Mr Om Kumar, who is from the eastern state of Jharkhand, said three of his cousins were trapped inside.

“If, somehow, they escape, they will save their lives – they will return home and will never work inside the tunnel again,” Mr Kumar, 20, said.

Mr Syed Ata Hasnain, a senior rescue official and retired general, on Nov 25 called for “patience”.

“A very difficult operation is going on,” he told reporters.

“When you do something with mountains, you cannot predict anything,” he added.

“This situation is exactly like war.” AFP
