China attempting to bore a rail tunnel straight through Mt Everest

It may be the world’s tallest mountain to climb, but now has
set itself an even greater Mt Everest challenge: attempting to bore a
tunnel straight through it.
Officials are considering building a
rail link from Chinese-controlled Tibet to which would ultimately
link the mountain state’s capital, Kathmandu, with Beijing – and would
need to pass beneath the Himalayan mountain range.
The new rail
route would boost trade and tourism between China and Nepal in a
development that risks more tension with India over China’s ambitions in
south .
The new line would join an existing line from
Qinghai, a central Chinese province, to Lhasa, the capital of
Chinese-controlled Tibet, and is being planned “at Nepal’s request”,
according to reports in the China Daily. A Tibetan official is cited as
saying it will be completed by 2020.
Everest’s 8848m summit sits
precisely on Nepal’s border with China. The rail project’s specific
details are few, but engineers may look for guidance to the makers of
the world’s current longest and deepest tunnel, under the Swiss Alps.

The Gotthard Base Tunnel is 56.3km long, and runs beneath more
than 2290m of mountain. It was completed in 2013, with trains expected
to pass through it next year. For most of the work, its builders used a
300-tonne mechanical mole to crunch through 38m of rock every day, with
the rest done by conventional drilling and blasting.
China’s
Foreign Minister, Wang Yi, visited Kathmandu in December and said the
line could eventually be extended to that city and beyond.
Chinese tourism to Nepal, which is home to eight of the world’s 14 peaks higher than 8000m is also growing.
Wang
Mengshu, of the Chinese Academy of Engineering, told state media: “If
the proposal becomes reality, bilateral trade, especially in
agricultural products, will get a strong boost, along with tourism.”
He
added: “The line will probably have to go through Qomolangma [the
Tibetan name for Everest], so workers may have to dig some very long
tunnels.”
The challenging Himalayan terrain, with its
“remarkable” ups and downs, means that trains on any line to Kathmandu
would probably have a maximum speed of 120km/h, he said.
Sino-Indian
tensions remain high, with both countries – home to 40 per cent of the
world’s population between them – seeking to shore up their influence in
their respective regions.
Not far from the proposed rail link
are areas which China and India both claim as their own, and over which
there was a border war in 1962.
