5 areas of concern for silica dust in underground hard ...

2021-7-11 · Silica dust has been present since the inception of hard rock mining. Silica dust is a natural mineral found in the earth’s crust and consists of silicon and oxygen. Its most common form is quartz and when it is broken into very fine dust particles beyond the naked eye it is known as respirable crystalline silica.

Health Hazards of Mining and Quarrying - ILO Encyclopaedia

2021-9-12 · 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.
