Respiratory Silicosis And Mining Safety Mining Safety

silicosis is a disabling and often fatal lung disease caused by breathing dust that has very small pieces of crystalline silica in it. crystalline silica is found in concrete, masonry, sandstone, rock, paint, and other abrasives. the cutting, breaking, crushing, drilling, grinding, or abrasive blasting of these materials may produce fine silica mining sandstone involves different techniques and the process is more expensive. however, the requirements of the glassmaking industry for high-silica sand with negligible contaminants motivate the operators to mine the sandstone, even at great expense.
