The prevalence of radiographic evidence of coal workers' pneumoconiosis and of respiratory impairment in a group of 1455 bituminous coal miners from six mines is compared to that present in a group of 518 miners from two anthracite mines. Data given for demographic characteristics of the populations, radiographic category, and spirometry and lung volumes for each of the two types of miners indicate that the prevalence of pneumoconiosis as a whole and progressive massive fibrosis is higher in the anthracite miners than in bituminous miners. Bronchitis is also found higher in anthracite miners, and increases in residual volume are noted. An unidentified agent is concluded to be in the working environment of the anthracite miner that puts him at a greater risk than the bituminous counterpart.
