[Cutters and drillers: 2 different coal pneumoconioses?].

J M Del Campo, J R Granda, E Pereiro

    Revue Des Maladies Respiratoires
    |January 1, 1984
    PubMed
    Summary

    Coal miners exhibit distinct pneumoconiosis types based on their role. Coal-cutters develop classic coal-workers pneumoconiosis, while drillers face a more aggressive silicosis from mixed dusts.

    Area of Science:

    • Occupational Medicine
    • Pulmonary Pathology
    • Radiology

    Background:

    • Pneumoconiosis classification systems are crucial for understanding lung diseases in miners.
    • Distinct occupational exposures in mining may lead to different forms of pneumoconiosis.

    Purpose of the Study:

    • To compare radiological findings and disease characteristics between coal-cutters and drillers.
    • To differentiate between coal-workers pneumoconiosis and silicosis in mining populations.

    Main Methods:

    • Radiographic analysis of 393 coal-cutters and 187 drillers using the BIT 1980 classification.
    • Independent review by two experienced pneumoconiosis experts.
    • Comparison of demographic data, respiratory symptoms, and lung function (VEMS).

    Main Results:

    • Coal-cutters showed predominantly "p" opacities and Category 1, typical of coal-workers pneumoconiosis.
    • Drillers presented with "q" and "v" opacities, Category 3, pseudo-tumoral masses, and hyperinflation, indicative of silicosis with mixed dusts.
    • Drillers had lower VEMS and more aggressive, incapacitating disease compared to coal-cutters.

    Conclusions:

    • Coal-cutters and drillers develop distinct types of pneumoconiosis due to differing exposures.
    • Drillers' disease (silicosis with mixed dusts) is more aggressive and incapacitating than coal-workers pneumoconiosis.
    • Recognizing these distinct types is vital for accurate epidemiological evaluations in coal miners.
