Jachymov had strategic importance for survival of the Soviet Union. Soviets invested into building mine and provided initial workforce. Jachymov was not some siberian gulag for wood choping. Soviets also paid for uranium. Mine was closed as too expensive.

How Czech communist party ran the mine, and what it did to its citizens is something else.

Regarding uranium extraction in Czechoslovakia, the Soviets later mined uranium in other sites by pumping sulfuric acid into the ground. This has caused a lasting ecological damage which has to be managed to this day.

The acid was meant to dissolve the ore and was then sucked back out. The only issue was that they ended up pumping a more sulfuric acid into the ground than sucking out. This created an underground lake of sulfuric acid in an with other underground water "lakes". This sulfuric lake is threatening to spill into these water sources.

I heard about this from my teachers at the university who were involved in the modelling of the underground spill. Using a limited number of wells, they were supposed to predict how the spill is spreading and what actions to take to stop it.

I found some pictures from the site here: https://zpravy.aktualne.cz/domaci/pitna-voda-tezba-uranu-kys...

On the East German side of the border, Uranium mining started essentially as gulag-style worker camps under Soviet control right after the war, and a few years later was moved into the "Wismut AG", which was a company under shared East German / Soviet ownership. From the tales of my grandparents, it was a mix of Soviet oppression and Wild West. In the Wismut, the miners were very well paid (for post-war East Germany), but they were a rowdy bunch and quite often had quarrels (also physical) with the East German police and Soviet camp guards (who of course couldn't simply "mow down" their highly qualified work force). Eventually in the mid- to late 50's, it calmed down, and working for the Wismut was more or less a normal job (albeit with a high risk of dying early of lung cancer and/or silicosis).

After the reuninification, the German government invested big into fixing the environmental damage that was done in 40 years, and that took over a decade. Props to them for this, the Erzgebirge is quite a nature paradise today.
