Abstract
Prolonged exposure to airborne respirable coal dust is responsible for coal worker's pneumoconiosis (CWP), commonly called black lung. Health research studies have identified that the prevalence and severity of CWP are directly related to both the amount of dust exposure and the coal rank. The amount of airborne respirable dust (ARD) smaller than 10 micrometers generated from breakage of different coals varies widely. NIOSH researchers conducted experiments to identify the causes of ARD liberation. Laboratory crushing experiments were conducted on a range of low- to high-volatile bituminous coals from eight mines (five eastern and western U.S. and three Polish). The results show that the proximate analysis of a coal sample can provide a very good indicator of the potential for a dust problem. For application to the coal mining, processing, and utilization industries, data from 977 national coal seams compiled by the U.S. Department of Energy was used to calculate this dust generation potential from an equation based on the NIOSH measured data. A simple procedure for this calculation is provided.
