“The vertical drilling will disturb the rock formation and will cause vibrations to the mountain,” stated Sundriyal, who is taken into account an skilled in native rock formations.

“The rocks in the Himalayas should be treated very cautiously and with very strong support. I’m afraid drilling will disturb the soil of the rock above the tunnel.”

On web site, authorities say each rescue choices are thought of protected choices, however are unable to inform which is able to deem handiest.

“Both vertical and horizontal drilling are safe,” stated Harpal Singh, the previous director of India’s Border Roads Organization that maintains the nation’s highway networks.

A panel of consultants instructed India’s Supreme Court that building of the highways will “lead to further landslides and soil erosion in an already sensitive environment,” in keeping with a 2020 report by the courtroom.

Authorities are investigating the reason for the tunnel collapse and are more likely to study the function of drilling on the mountain. CNN has contacted the Ministry of Environment, Forest and Climate Change of India.

On Friday, tunneling skilled Anrold Dix, an Australian engineer who has flown to India to seek the advice of on the rescue effort stated they have been placing the protection on the core of the operation.

“With each option, we are considering how do we make sure that 41 men come home safe and we don’t hurt anyone,” Dix instructed reporters.
