$8000 to dig a 1m hole sounds very high - that's months of someone's salary. Surely the best drilling machines can beat the cost of paying someone with a shovel

$8000 to dig a 1m hole sounds very high - that's months of someone's salary. Surely the best drilling machines can beat the cost of paying someone with a shovel for a month?
But mostly they won't be digging the holes, they will be using shafts left over from earlier mining operations.
- adrianN 6y agoThose prices are probably only true once you go deep enough to require permits, ground water management and all the other complications of very deep holes.
- LordHeini 6y agoThat is what i found: https://minewiki.engineering.queensu.ca/mediawiki/index.php/Shaft_construction https://minewiki.engineering.queensu.ca/mediawiki/index.php/... Honestly i would have thought it to be more expensive. At higher depths the ground pressure is enormous and you need a lot of bracing. Then there is water management, air, transportation of the dug out material... When there is rock you usually need blasting or gargantuan drills which i am not sure even exists in the required diameter.
- satisfaction 6y agoOH come on, I'm sure you can imagine the complexity of digging grows as the depth grows. the first meter would cost 100$ the second 150$, the 3rd 200$, the fourth 500$ the fifth 550$, the sixth 600$, etc.
