I downloaded the MSHA's (Mine Safety and Health Administration) public datasets and create a visualization of all the mines in the US complete with the operators and details on each site.

There are 3 mines on Manhattan; is that correct?

I'm glad it's those kinds of mines rather than the ones I first thought of.

How many of these pose asbestos hazards like the Libby mine?

Based on the info if you click into them, likely no. I would have expected them to be incidental materials from tunneling, but reading the description that's not the case.

This doesn't seem to be complete. It's missing the Waste Isolation Pilot Plant, for example, which should be southeast of Carlsbad, NM. It's a underground salt (metal/non-metal) mine, and MSHA definitely regulates it

This seems to include cement works and other processing plants that have somewhat mine-like output but aren't actually extracting anything from the ground at that site.

I love the idea of a site like this existing but the expanding dots is a really bad way to visualize this.

I saw your title and my first thought was "Why are there landmines in the US?" lol.
