Mining is the practice of extracting ore, coal, clays, soils, or minerals from the ground for the purpose of using them. Mines have existed for thousands of years. In ancient times mines consisted of short tunnels dug into the sides of hills or mountains where veins of metals, minerals, or
Freshly fractured silica dust appears to be more reactive and more hazardous than old or stale dust. This may be a consequence of a relatively higher surface charge on freshly formed particles. The most common processes that produce respirable silica dust in mining and quarrying are drilling, blasting and cutting silica-containing rock.
