Oct 06, 2020  Asbestos tailings piles don’t contain that much asbestos. Copper mine tailings don’t contain that much copper. Gold mine tailings are very low in gold. Good Lord, spare us from modern scientists working on engineering solutions to non-problems. When they mused on using fans to blow 400ppm CO2 air on fluffy asbestos I laughed until I cried.

Coal Mininig Asbestos Exposure - Risk of Mesothelioma

Mar 11, 2021  Coal mine dust, explosions and cave-ins all pose known dangers to coal miners. One danger not as well-known is coal mining asbestos exposure. As coal was pulled from the earth and processed, miners, contractors and refinery workers were all at risk of inhaling asbestos.
