The history of research on occupationally related health concerns of coal miners is reviewed in relation to methodological developments in the field. The first round of the National Study of Coalworkers' Pneumoconiosis began August 12, 1969, 4 months before enactment of the Federal Coal Mine Health and Safety Act of 1969, and lasted until May 19, 1971. Study included 29 bituminous and two anthracite mines employing a total of 10,032 miners, of which over 90% were voluntarily examined. The second round of examination of the National Study of Coalworkers' Pneumoconiosis was begun on July 18, 1972, and extended to Feb. 17, 1975. The number of mines involved was increased to 36. It is suggested that if one discounts the first round of the National Study of Coalworkers' Pneumoconiosis and the examinations made during those periods when the persons being examined were mostly men with little prior mining experience, it appears that the rate of pneumoconiosis among working underground miners is probably somewhere between 10% and 15%. While this does not appear to represent a significant decrease in the proportion of miners with pneumoconiosis since the Federal Coal Mine Health and Safety Act was passed, there does seem to be a marked decrease in the number of working miners with complicated pneumoconiosis or the higher levels of simple pneumoconiosis.
