Citing his 37 year’ s experience \u00a0of working as a geologist\u00a0 with GSI, Pangti said that in highly tectonic region like Himalayas, the significance of\u00a0 geology\u00a0 becomes significant and\u00a0 to start any infrastructure projects in such areas, the complete knowledge of geological situation of the region is essential. This fact was apparently neglected in this project.<\/p>\n
“The private companies that are coming to construct road tunnels, communication or hydro projects in Himalayan region, are not taking the knowledge of geological and tectonic situation of that particular place, that is why several such projects are failing in entire Himalayan region. The geological formation is different at different locations, designs of projects be prepared according to rock formation of that particular area,” said the retired Additional Director General of GSI.<\/p>\n
Tribhuwan Singh Pangti further suggested that a detailed geological and glaciological study of Himalayan region be done before letting any infrastructural project in the region. “Though, tunnels are viable option to construct roads in the region but it should not be done without studying geological and glaciological conditions of particular places\u201d, said Pangti.<\/p>\n
\u201cThere are several support system measures used in tunnels in the time of emergency exit needed, these are, shot create, cement grouting, rib support system, rock bolting and chemical grouting. These systems are applied keeping in mind the space of rib and rock mass condition. I have no information if any of these safety measures were available in Silkyara tunnel or not,\u201d he added.<\/p>\n
Tribhuwan Singh Pangti said that there should be a high powered committee of technical experts including prominent geologists and geo-technicians in place to give sound scientific advise regarding construction of any project in the entire Himalayan areas of the country. He said that for speedy rescue of the trapped labourers, there should be horizontal digging of the tunnel from both the side.<\/p>\n
