Silica dust is generated by mining activities, including cutting, sanding, drilling, crushing, grinding, sawing, scraping, jackhammering, excavating, and hauling materials that contain silica. Silica dust also mixes with other dusts created during mining, such as coal dust, to create an increased risk of illness and death.
