Rescue operations to evacuate 41 workers trapped in the tunnel resumed on Thursday morning after an iron mesh that had come in the path of the auger machine drilling an escape path was removed.
The resumption of drilling with the auger machine is likely to speed up the rescue efforts.
A heavy-duty drilling machine flown in by the Indian Air Force (IAF) from Delhi began boring through the rubble of a collapsed tunnel on the Char Dham route in Uttarakhand Thursday, in a fresh attempt to create an escape passage for 40 workers trapped inside for four days.
Micro tunnelling expert Chris Cooper said on Monday that all the debris from the auger machine has been removed and manual drilling to reach the trapped labourers will start in a few hours.
The National Disaster Management Authority (NDMA) on Friday said no progress has been made since Thursday in drilling through the debris at the Silkyara tunnel in Uttarakhand to rescue 41 trapped workers but assured that the drilling by auger machine will start soon.
Uttarakhand Chief Minister Pushkar Singh Dhami on Tuesday said none of the 41 labourers rescued from an under-construction road tunnel in Uttarkashi district was in a critical condition.
'Even, nature looks cheerful today. A cool wind has stirred up the leaves and trees. The weather is good. We are hopeful'
Rat-hole mining may be illegal but the talent and experience of rat-hole miners were used in the rescue operation to save the 41 workers trapped in the Silkyara tunnel, a National Disaster Management Authority member said on Tuesday.
For them it was a late Diwali, as the tunnel collapse happened on November 12, the day of the the festival.
At the Silkyara tunnel in Uttarkashi, at least 12 experts have been called by Trenchless Engineering Services Private Limited and Navayuga Engineers Private limited for applying the rat-hole mining technique horizontally in the collapsed part of the main structure.
'We humans may not have not created natural disasters, but we have definitely amplified their impact.'
The advisory, issued by the Ministry of Information and Broadcasting, also told private television channels to be sensitive in their reportage, especially while putting out headlines and videos of the rescue operations, considering the psychological status of family members of the trapped workers.
Rescue workers pulled out all 41 workers trapped in Uttarakhand's Silkyara tunnel in a multi-agency rescue operation that hovered between hope and despair for 16 days.
He said he has spoken to the trapped labourers.
A high performance drilling machine was brought in Uttarkashi from Indore on Saturday to pierce through the rubble of the collapsed tunnel on the Char Dham route and was being assembled before it is deployed to resume drilling, officials at the site said.
Drilling at the collapsed Silkyara tunnel to rescue 41 men trapped inside for 12 days was halted again on Friday, officials said.
Here is the timeline of the disaster and the rescue efforts that followed.
'I feel numb with the trauma we have been going through ever since we first got the news. For close to two weeks, we have been hearing my child will be rescued today. That today never comes'
The 41 workers trapped in Uttarakhand's Silkyara tunnel for the last 11 days are likely to be rescued in the next few hours or by tomorrow, National Disaster Management Authority (NDMA) member Lt Gen (retd) Syed Ata Hasnain said on Thursday evening.
Dr Ravikant said the workers were thoroughly examined and their blood test, X-ray, and ECG reports were normal.
The minister for road transport and highways, who was accompanied by Uttarakhand Chief Minister Pushkar Singh Dhami, said the rescue operation is challenging as the soil strata in the Himalayan region is not uniform.
A senior Uttarakhand official at the site said drilling was complete.
It isn't that a person occupying high office has no right to do what he/she likes. For sure, they do; after all, they are human. But there are also things like priority, timing and sense of larger country. Sadly, we live in a world awash in tunnel vision, asserts Shyam G Menon.
'The rocks, the geology of the Himalayas will always spring surprises.' 'It's basically force majeure and the will of god.'
He further said that the "focus is on horizontal drilling" as rock formation has created challenges for vertical drilling.
The rat-hole miners said the chief minister's gesture was 'not commensurate' with the role they had played.
"The new food supply pipeline has also made it easier to supply better food in larger quantities to them, which is a good thing. Otherwise the situation remains the same," said Negi, who spoke to his brother.
Boring through the rubble of the collapsed Silkyara tunnel was put on hold again on Thursday apparently after cracks appeared in the platform on which the drilling machine rests, in a fresh hurdle to the rescue of 41 workers trapped inside for 11 days.
The labourers have been trapped since Sunday morning when a part of the tunnel collapsed following a landslide.
'These kinds of tunnels are not meant for the Himalayas.' 'Development should be good for all people and not where you make a tunnel and 40 people get trapped.'
'What we are witnessing is not a freak incidence or a freak occurrence, but a new climate reality where warming oceans, monsoon variability and local geography are combining to produce extreme events.'
Using drones and remote-sensing equipment, rescue teams intensified efforts on Wednesday to reach the 25-35 men trapped in a sludge-choked tunnel since the Uttarakhand glacier disaster three days ago and more than 170 remained missing, hopes of finding them alive fading with every passing hour.
As the last ambulance carrying one of the 41 labourers rescued from an under-construction road tunnel left the site in Uttarakhand's Uttarkashi district for a community health centre on Tuesday evening, Chief Minister Pushkar Singh Dhami and Union minister V K Singh went straight to a temple of local deity Baba Baukhnag to express their gratitude for his blessings.
'I would put my hand in the ground and have a little listen to what the mountain was doing.' 'Actually, it was still collapsing.' 'And there was a very real possibility that at some stage, without warning, the collapse could continue -- and continue across us, the people who were doing the rescue and also across to the men on the other side, who were being rescued.'
'We are hoping that in three-four days we will surely get a positive result.'
Uttarakhand Chief Minister Pushkar Singh Dhami Wednesday met the workers rescued from the Silkyara tunnel and kept under medical observation at a hospital in Chinyalisaur and handed over Rs 1 lakh to each of them.
Drilling at the collapsed portion of the tunnel to rescue the trapped men was halted again on Friday night, in yet another setback to the multi-agency effort.
A six-inch pipe has been laid at the Silkyara tunnel through which nutritious food and medicines could be supplied to the 41 labourers, trapped for over a week after parts of the under-construction structure collapsed following a landslide.
The auger machine was facing repeated obstructions in the rubble in the past few days.
Jaymal Singh Negi mentioned that his brother informed him about the trapped men engaging in yoga and exercises inside the tunnel.
