\nIndian rescuers have drilled two-thirds of the way through debris towards 41 workers trapped in a collapsed road tunnel, officials said on Wednesday, warning that the next 24 hours could be critical.
\nEngineers are working to drive a steel pipe through at least 57 metres of the tonnes of earth, concrete and rubble that have divided the trapped men from freedom since a portion of the under-construction tunnel in the northern Himalayan state of Uttarakhand collapsed 11 days ago.
\nLooking into the Silkyara tunnel entrance on Wednesday, an AFP journalist could see sparks flying as workers welded metal tube sections together, with the site busy as excavators and heavy trucks brought in equipment.
\n\u201cI am very happy to share \u2026 that 39m of drilling has been completed,\u201d said Mahmood Ahmad, a road and highways ministry official involved in the operations.
\n\u201cIf there is no blockage, we hope there could be happy news late tonight or tomorrow,\u201d Ahmad told reporters at the site.
\n\u201cWe are moving forward at a fast pace,\u201d he added. \u201cStay hopeful, pray that the pace continues.\u201d<\/p>\n
However, he warned that the remaining section yet to be drilled was critical.<\/p>\n
Challenging Himalayan terrain
\nRescue efforts have been slow, complicated by falling debris as well as repeated breakdowns of crucial heavy-drilling machines.<\/p>\n
The giant earth-boring machine last week ran into boulders, and drilling was put on hold for more than three days after a cracking sound in the roof.<\/p>\n
Uttarakhand chief minister Pushkar Singh Dhami on Wednesday spoke of the \u201cpositive progress made in the last 24 hours\u201d, without further details.<\/p>\n
But a government statement also noted that \u201ctimelines provided are subject to change due to technical glitches, the challenging Himalayan terrain and unforeseen emergencies.\u201d<\/p>\n
In case the route through the main tunnel entrance does not work, blasting and drilling have also begun from the far end of the unfinished tunnel, nearly half a kilometre long. Preparations have also been made for a risky vertical shaft directly above.<\/p>\n
On the forested hill above, rescuers have cut an entirely new track to bring heavy equipment above the men, where a machine to dig an 89m vertical shaft is being installed \u2014 a complex dig above the men in an area that has already suffered a collapse.<\/p>\n
The workers were seen alive for the first time on Tuesday, 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
