Speaking to the media, Dhami mentioned on Saturday that Prime Minister Narendra Modi could be very delicate in the direction of the employees trapped within the Silkyara tunnel and he’s taking detailed info daily concerning the well-being of the employees. Expressing hope for the profitable rescue of the trapped employees, Dhami mentioned, “We will soon be successful in evacuating the labour brothers safely.””Prime Minister Narendra Modi is very sensitive towards the workers trapped in Silkyara, Uttarkashi Tunnel. The Prime Minister is taking detailed information every day about the well-being of the workers and the ongoing relief and rescue operations in the tunnel. Central agencies, state administration and teams of international experts are working on all options, we will soon be successful in evacuating the labour brothers safely,” CM Pushkar Singh Dhami posted on X.
Meanwhile, worldwide tunnel knowledgeable Arnold Dix, who’s aiding within the rescue course of, mentioned on Saturday that there have been a number of methods to rescue the trapped employees and the 41 males contained in the Silkyara tunnel are coming residence safely. He additionally spoke concerning the breakdown of the Auger machine, saying there wouldn’t be any new auger machine and different strategies can be used for rescue operations.
“There are multiple ways. It’s not just one way. At the moment, everything is fine. You will not see the augering anymore. Auger’s work is finished. The auger (machine) has broken. It’s irreparable. It is disrupted. No more work from Auger. No more drilling from the Auger. There will not be a new auger,” International Tunnelling Expert Arnold Dix mentioned.
“I said that 41 men are coming home safely and we’re not going to hurt anybody in the process. We’re looking at, as we’ve always been, multiple options. But with each option we’re considering right now, to do that, we evaluate all of the evidence that we have about how the mountain is behaving. Now, the mountain has again resisted the Auger, so we’re rethinking our approach. This is a decision that’s been made by all the experts, including Indian and local experts. The Himalayan experts from India are providing us with all the information we need. I am confident that 41 men are coming home.” added Arnold Dix.
“I’ll just say that I’ve always promised that they’d be home by Christmas. If you remember right from the beginning, I’ve never been. It is a long time, and they’re safe and they’re well, and if we rush, we can cause another problem in there. So we’re taking our time and being very considerate, and that’s what all these meetings are at the moment. Of course, there’ll be an announcement shortly about what we’re going to do,” he added.
Meanwhile, the Sutlej Jal Vidyut Nigam (SJVN) crew has as soon as once more come on standby mode to do vertical drilling.
The crew of 12 folks at SJVN Limited is totally able to do the drilling so long as they get the order.
Officials are exploring the choice of vertical drilling too, because the heavy-duty auger machine that was used within the horizontal drilling by the mouth of the tunnel from the Silyara aspect hit an impediment on Friday night.
A closing determination on the vertical drilling choice is prone to be taken by Sutlej Jal Vidyut Nigam (SJVN) and the Oil and Natural Gas Corporation.
An SJVN official mentioned, “We have given a proposal to the administration to do vertical drilling in 5 to 6 days; our team has done the survey for drilling; and apart from this, their drilling machine has also reached the spot to do the drilling. We are just waiting for the order to come.””The vertical drilling will be done from the top of the tunnel and about 85 to 90 metres will have to be drilled, which will take about 5 to 6 days. When drilling from inside the tunnel When the work of building the rescue tunnel gained momentum, the plan of doing vertical drilling was put on hold, but now, due to the hurdles we are facing, we have once again come into standby mode to see if the administration needs vertical drilling. We will start our work immediately after receiving the order,” added the SJVN officialOfficials earlier in the present day mentioned that guide drilling will start quickly to chop by the rubble that separates rescuers from the 41 trapped employees within the collapsed portion of the Silkyara tunnel.
According to officers, guide drillers will get to work as soon as the US-made, heavy-duty Auger drilling machine is faraway from the pipeline by which the trapped employees are to be introduced out.
Manual drillers will work to chop by the remaining rubble that separates the rescuers from the employees and allow the insertion of the pipeline by the additional few metres which are but to be lined.
The ongoing operation to rescue employees, who had been trapped after a portion of the tunnel collapsed on November 12, entered its 14th day on Saturday.
Success may quickly be achieved in taking the Auger driller out of the pipeline, officers knowledgeable additional, including that the heavy-duty drillers may now be moved again by 22 metres.
Speaking to ANI, a senior official concerned with the rescue operation mentioned guide drilling may begin quickly.
He added that the remaining particles, extending roughly as much as 6 to 9 metres, which stands between the rescuers and the trapped employees, shall be eliminated by guide drilling.
Elaborating on the the explanation why the officers concerned within the rescue operation have determined to take away the Auger from the pipeline, the senior official instructed ANI, “While drilling with the US-made Auger machine, if we hit an obstruction every two to three feet, we have to remove it. And, every time we hit an obstruction, we have to roll Auger back 50 metres (up to which the pipeline has been laid). After running repairs, the machine has to be pushed back up to 50 metres, which takes about 5 to 7 hours. This is the reason why the rescue operation is taking longer than it should.”He knowledgeable them additional that after drilling as much as an additional 5 metres, the rescuers will attain the ultimate few metres that separate them from the trapped employees.
However, the officers shunned quoting a timeframe inside which the rescue mission might be accomplished, saying that they had been hopeful of a optimistic consequence as soon as the guide drilling begins on Saturday.
Earlier, a crew of consultants, who got here to conduct a survey on the tunnel web site, knowledgeable that there have been no heavy objects as much as 5 metres contained in the tunnel.
The crew from Parsan Overseas Pvt Ltd Delhi used the ground-penetrating radar (GPR) approach to look at the rescue tunnel.
Ground Penetrating Radar, also called GPR, Georadar, Subsurface Interface Radar, or Geo-probing Radar, is a very non-destructive approach to provide a cross-section profile of the subsurface with none drilling, trenching or floor disturbances.GPR profiles are used for evaluating the situation and depth of buried objects and to analyze the presence and continuity of pure subsurface situations and options.
After inspecting the rescue tunnel, geophysicist and GPR survey crew member B Chendhoor mentioned they had been known as to the scene after the Auger driller hit an obstruction.
After a portion of the tunnel caved in on November 12, the particles falling within the 60-metre stretch on the Silkyara aspect of the tunnel trapped 41 labourers inside.
The employees are trapped in a 2 km-built portion, which is full, together with concrete work, which supplies them security. (ANI)
