Coal mine dust lung disease in the modern era - .

INTRODUCTION. Inhalation of dust generated by coal mining can lead to the development of coal mine dust lung disease (CMDLD). In addition to the classical coal workers' pneumoconiosis (CWP) and its severe and potentially fatal form, complicated or progressive massive fibrosis (PMF), CMDLD also includes mixed‐dust pneumoconiosis with coexistent silica exposure, chronic bronchitis, emphysema ...
