An epidemiologic survey of 9076 coal miners during 1969 to 1971 shows that in miners with simple coal workers' pneumoconiosis, no relationship exists between ventilatory capacity and radiographic category, although complicated pneumoconiosis leads to definite ventilatory impairment, and residual volume shows a slight increase with increasing radiographic category of simple pneumoconiosis. Significant geographic variations in ventilatory capacity and lung volumes appear to be related partly to the type of coal dust to which miners are exposed, partly to the ethnic origin of the miners, and partly to nonoccupational factors. While the occupation of coal mining may lead to minor reductions of ventilatory capacity in certain circumstances, such reductions are minimal in the absence of complicated pneumoconiosis and would not be associated with respiratory disability.
