Spreading Asbestos Fibres and Running Fans Might Help

Oct 07, 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.

Miners and Asbestos Exposure Tremolite Asbestos in Mines

Miners and mining communities are among those at the greatest risk of contracting asbestos-related diseases. Asbestos is a naturally occurring fibrous mineral that was extensively mined during the early 20th century. Because asbestos is durable and flexible, as well as fire- and heat-resistant, it was used in manufacturing over 3,000 products.

Underground Mine Ventilation Technical Aspects of Mining

In most cases and especially in large, deep mines, electric fans are used. In mechanical ventilation, pressure difference is created by operating one or more fans in an airway. Each fan creates a certain amount of pressure, and that pressure is gradually lost as the air passes through the airway against its resistance. Most mining fans are of
