OIL GAS: SILICA DUST CONTROL IN HYDRAULIC FRACTURING. Employee exposure to silica dust generation during hydraulic fracturing operations is a continuing concern for the oil and gas industry. Energy and production (EP) companies face ongoing scrutiny of the impact of hydraulic fracturing operations on air quality.
Silica's facilities, strategically located in 13 states and globally in China, are situated on or near the best available mineral resources for that geographical region. Each plant has been equipped with the right processing equipment, quality systems and shipping capabilities necessary to supply our valued customers and innovative thinking.
mining operation, a gravimetric sample of the respirable fraction of airborne dust is collected. This sample is then analyzed for silica content using Xray diffraction. If the percent of silica in the sample exceeds 1%, a respirable dust standard is calculated by dividing 10 by the (% silica + 2).
Mining Silica Dust Control Systems Coal mining operations can generate significant amounts of airborne respirable coal dust, the inhalation of which can lead to pneumoconiosis, a disabling and potentially fatal lung disease.

Jan 26, 2016· Fly over of a sand mine, with captions to help understand what goes on in the processing of sand.
Silica is the name given to a group of minerals composed of silicon and oxygen, the two most abundant elements in the earth's crust. Silica is found commonly in the crystalline state and rarely in an amorphous state. Sand consists of small grains or particles of mineral and rock fragments.
The basic mine plant for underground mining operations consists of headframe, hoist, timber framing and storage area, miner's change house, compressor house, machine shops, warehouse, office, ore storage, ore loading, and shipping facilities.
