Anthracosis
Carbon dust (coal mine dust):
Coal miner’s pneumoconiosis
• Two phases in coal miners pneumoconiosis
1. Simple pneumoconiosis: little ventilatory impairment
– Around 12 yr. of exposure needed for this phase to appear
2. Progressive massive fibrosis (PMF): severe respiratory disability and frequently results in premature death
– Once a background of simple pneumoconiosis has been reached, a PMF may develop out of it even if the exposure is ceased
• The risk of death among coal miners has been appx twice that of the general population
• Coal-miners’ pneumoconiosis is a notifiable disease under Indian Mines Act of 1952
• It is also compensatable in Workmen's Compensation (Amendment) Act, 1959
