Miners faced asbestos from two directions. Some mined asbestos-bearing ore itself — chrysotile, tremolite-contaminated talc, and vermiculite — inhaling raw fiber straight from the rock. Others mined coal, metal, or minerals and were exposed to the asbestos friction and brake components on the heavy equipment that moved the ore. Both the raw minerals and the equipment parts are documented as allegedly asbestos-containing.
How Miners Were Exposed
In asbestos, talc, and vermiculite mines, drilling, blasting, crushing, and hauling ore released raw fiber into the air of the pit and the mill — the most direct exposure of any trade. Tremolite, an amphibole asbestos, occurs naturally alongside many talc and vermiculite deposits, so even workers mining a “non-asbestos” mineral could breathe amphibole fiber. In coal and metal mines, the exposure came from the machinery: draglines, power shovels, haul trucks, hoists, and crushers all ran asbestos brake blocks, band linings, and friction drive belts. Every brake reline, drive-belt change, and hoist rebuild in the maintenance shop released friction dust.
The Asbestos Materials — and the Products They Came In
Exposure tracked to raw asbestos-bearing minerals and the friction components on mining equipment. Each links to products documented in the AsbestosIndex as allegedly asbestos-containing:
Raw asbestos ore — mined, crushed, and milled:
- Asbestos Corporation Limited (Quebec) asbestos mining exposure · Carey Canada / Johns-Manville asbestos mine (Quebec)
Tremolite-contaminated talc — mined and milled from amphibole-bearing deposits:
- Cyprus tremolite-contaminated industrial talc · R.T. Vanderbilt Gouverneur talc (tremolite asbestos) · Imerys tremolite-contaminated industrial talc
Vermiculite — mined and expanded from asbestos-bearing ore:
Mining-equipment friction & brake components — relined and changed in the shop:
- Bucyrus-Erie asbestos brake blocks (draglines & shovels) · Marion Power Shovel asbestos brake blocks
- P&H (Harnischfeger) mine-hoist & shovel brake linings · Euclid / Terex mining-haul asbestos brake blocks · Nordberg cone-crusher asbestos fabric drive belt

Take-Home Risk to Families
Ore, talc, and friction dust rode home in miners’ clothing and hair, exposing spouses and children who never went underground — often through the laundry. See take-home asbestos exposure.
If you worked as a miner and were exposed to asbestos ore, tremolite-contaminated talc, vermiculite, or asbestos friction components on mining equipment, and you were diagnosed with mesothelioma or another asbestos-related disease after that exposure, you may have a legal claim.
