The Pneumoconiosis Problem in Coal-mines

Pneumoconiosis in Central Indian coal-mines.

Extensive surveys carried out in Europe and America have shown the incidence of coalworkers' pneumoconiosis to be widespread (Flinn, Seifert, Brinton, Jones, and Franks, 1941; Fletcher, 1955). In India, however, the prevalence of this disease has never been investigated, and a report published by the government of India in 1946 (Deshpande, 1946) stated that there was no conclusive evidence that...

Apparent onset of coal-workers' pneumoconiosis after leaving the mines.

The answer to the second question is increasingly likely to be 'yes' towards each end of the scale. Loss of binocular visual acuity is a greater loss in a man with poor eyesight because visual acuity falls from a higher level using both eyes to a lower level using one, even thou...

Airborne dust in coal mines: the sampling problem.

Effect of Dust Suppression Measures on the Prevalence of Coal-workers' Pneumoconiosis in the Dutch Coal-mines.

The underground workers in the Dutch coal-mines have been radiographed (70 mm.) seven times since 1949. The prevalence of coal-miners' pneumoconiosis shows a continuous decrease in all age groups. To evaluate the effect of the intensive system of dust suppression over this period a cohort analysis was made of the proportion ofmen with pneumoconiosis with the same number of years of exposure und...
