Washington — Surface coal miners, especially those who work in drilling, may be exposed to higher concentrations of respirable dust or quartz. This puts them at elevated risk of coal workers’ pneumoconiosis – a deadly but preventable disease known as black lung, results of a recent NIOSH study show. To analyze coal dust exposure among surface mine workers, researchers used nearly …

Mining of thin coal seams has been associated with greater silica exposure because more rock must be cut above and below the seam to deploy mining equipment . Improvements in processing techniques have made this type of mining more profitable because modern preparation plants can more easily separate coal from large amounts of waste rock than in the past ( 28 ).
Feldspar and quartz are the most significant silicate minerals. Silicon alloys include a variety of metals, including iron, aluminum, copper, nickel, manganese and ferrochromium. Relation to Mining. In almost all cases, silica mining uses open pit or dredging mining methods with standard mining equipment.
20-06-2019· And the sampling misses episodes of high exposures, including the cutting of solid silica-bearing rock, often for months at a time, as mining companies try to reach new coal seams.

Coal mining leads to silica exposure, but the extent to which RA can be attributed to coal mining has not been estimated. We studied the association of RA with work-related coal and silica exposure in the Appalachian region of the US, given its geographic concentration of mining and data showing a high population prevalence of arthritis.

Respirable crystalline silica can cause fibrous or scar tissue to form in the lungs (silica induced pneumoconiosis) that reduces the lung’s ability to extract oxygen from the air. Respirable crystalline silica is more likely to be harmful to your health than respirable coal dust. It is also now recognised as a carcinogen. Symptoms:
