An 18' in diameter tunnel, 300 miles long will generate approximately
15 million cubic yards of spoil (earth and rock dug out to make the tunnel).
That is approximately a half a million truckloads of the largest dump trucks
Caterpillar makes.
Let me show my work...
Volume of a cylinder == area of the base * height
Area of a circle == (radius ** 2) * pi
Area in sq ft == (9 ** 2) * 3.14159
== 81 * 3.14159
== 254.87 sq ft
Height in ft == 300 mi * 5280 ft/mile
== 1,584,000 ft
Vol of cyl == 254.47 sq ft * 1,584,000 ft
== 403,078,563.36 ft ** 3
Cu ft to cu yd == 403,078,563.36 ft ** 3 / 27
== 14928835.68 yd ** 3
Caterpillar's largest dump truck holds a fraction over 30 yd ** 3
so that's just under a half million truckloads.
Millions of people would see that much traffic and the hole in the
ground would be clearly visible from the air.
It's extremely unlikely, at best.
Well, all my nice formatting got messed up but I stand by the calculations...
OK, let's do some arithmetic...
