30 minutes of grainy 80s footage in those links - I think it's better to provide at least the wiki link in any sort of discussion forum. If you're on discord or a chat, videos might be the norm, but forums/threaded discussions are text native, so it's better to provide a link to a text resource.
And it's crazy that a 14 inch hole into the salt mine resulted in all that chaos.
There's a salt mine mostly under Cayuga Lake in New York, in Lansing. When we bought our current house we had to sign a paper indicating we knew there was a mine somewhere near (underground about a mile to the north.) The risk of sinkholes or deformation from future collapse is always there, although not specifically for us as we are too far away. Development patterns change as you get to the area where the mine is: fewer (and older) homes, more commercial development.
What happens when they run out of salt? All the salt they put on the roads must end up back in the lakes but not in a way that is as easy to extract, right?
When that one mine runs out of salt? It will be closed. We as a humanity will not run out of salt, some places have the opposite problem: https://en.wikipedia.org/wiki/Monte_Kali
"According to the Werra Potash Mining Museum in Heringen, Monte Kali has been in operation since 1976; as of August 2016, it covered 98 hectares (240 acres) and contained approximately 201 million tonnes of salt, with another 900 tonnes being added every hour and 7.2 million tonnes a year."
Out of many worries about this world and its future, running out of salt is really at the bottom of the list.
You can always extract it form the sea by mere evaporation like our ancestors did. Plus salt deposits in the ground all over the world are massive, we had salty seas for billions of years.
In my undergrad I did a grad course on advanced mine ventilation, modeling the fluid dynamics of clearing out blast gasses from a room and pillar salt mine in Southern Ontario. The company had reached out to the professor a year or two ago asking for help understanding why it took so long for blast gasses to clear (which is obviously something to minimize). I was pretty proud I was able to reproduce the measured air velocities with my model, but while preparing my presentation at the end of the semester, I read the a month before I started my project the mine had switched to road headers (mechanical rock breaking, appropriate only in soft rock mines like salt, potash, and coal) and so my research, while interesting, seemed a little pointless.
They have some really unique challenges in salt mines, for those who enjoy reading into it. "Les Îles de la Madelaine" in the St. Lawrence seaway is a kitesurfing destination with an absolutely incredible salt mine, for anyone curious[1].
The last chapter in the lives of a lot of Great Lakes freighters is hauling salt. Apparently it’s no better for ships than it is for cars.
If you get a chance, the steamship Mather is docked near the Great Lakes Science Center in Cleveland. It was the flagship of the Cleveland Cliffs line, and was spared the fate of hauling salt. You can tour it, and if you book ahead, you can get an extended belowdecks tour that includes machinery spaces that you don’t see on the regular tour.
I spent part of my childhood in Winsford, a salt mining town in the UK (its other claim to fame being that it was where Neville Southall played before Everton). Every time I pass a yellow bin of salt for gritting the roads, I get to feel a little bit of nostalgia (before falling over because councils no longer have enough money to grit the roads and pavements).

That's why they made you sign the waiver obviously

I mean, you could sell salt ffs why just dump it? And what happens when it rains, surely it's absolutely fucking that soil for years to come

It's worth your time and money, unless you have a particularly vivid imagination. You ride a skip 600 feet down.

But then I wondered if modern mining engineering is a solved problem? In that they mostly know how to make safe tunnels?
Then I looked up how deep Erie is and it’s pretty shallow, with an average depth of 62 ft!
