mining activities. Miner operators can reduce the amount of silica-containing dust generated by staying in-seam while mining. Cutting sandstone top and/or bottom while mining generates excessive amounts of silica-containing dust. Mining and bolting should be completed on cycle, to limit the number of times the roof bolter works downwind ...

Depending on how the silica sand was formed, quartz grains may be sharp and angular or rounded. For industrial use, pure deposits of silica capable of yielding products of at least 98% SiO2 are required. Silica sand may be produced from sandstone, quartzite and loosely cemented or unconsolidated sand deposits.
