The risk of pulmonary tuberculosis in underground copper ...

Aug 23, 2016· Pulmonary tuberculosis (PTB) among underground miners exposed to silica remains a global problem. Although well described in gold and coal mining, risk in other mining entities are not as well documented. This study aims to determine dust-related dose response risk for PTB among underground miners exposed to silica dust in Zambia's copper mines.

Coal Mining, Rock Drilling: Silicosis

Traditionally rock drillers in underground coal mines were thought to be at risk of silicosis. Surface Mining Process. An early step in the surface or strip mining process is the removal of topsoil and other overburden materials, including sandstones, shales, limestones, and unconsolidated soils.

Pneumoconiosis Symptoms, Causes and Risk Factors ...

Acute silicosis is rare and generally occurs only after extremely high exposures, but it causes death in most cases. Coal dust is made of carbon-containing particles, and coal miners are at risk of inhaling this dust. Coal miners may also be exposed to silica-containing dust because coal mining may involve some drilling into silica-containing rock.

Coal Mine Dust Exposures and Associated Health Outcomes

Acute Silicosis Responding to Corticosteroid Therapy - CHEST

Not well-appreciated is the potential for development of acute silicosis among drillers at surface coal mines. We report the case of a 33-year-old man who worked primarily at surface drilling, developed acute silicosis within three years of beginning exposure, and who initially responded dramatically to corticosteroid therapy.

Final Rule - Mine Safety and Health Administration (MSHA)

The final rule is projected to have a greater impact on reducing risk for underground miners than for surface miners. Although the final rule will benefit coal mine workers who are exposed to average respirable dust concentrations both above and below the final 1.5 mg/m3and 0.5 mg/m3standards, it is projected to have its greatest impact on ...
