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.

The six commercial asbestos minerals (chrysotile, fibrous actinolite, crocidolite, amosite, fibrous tremolite, and fibrous anthophyllite) are classified by the IARC as carcinogenic to humans. There are currently several lines of research dealing with the inertisation of asbestos minerals among which the dry grinding process has received considerable interest.

In Canada, over 95% of asbestos is mined in open-mining operations that involve drilling and blasting, and this contributes more air emissions than underground mining operations (Sebastien et al. 1984). Other anthropogenic sources of asbestos emissions besides mining are the crushing, screening, and milling of the ore, the processing of
