Abstract
During the period from May 1984 through August 1989, samples were collected from 491 mines from 66 different mineral commodities by the National Occupational Health Survey of Mining (NOHSM) as part of an effort to set regulatory priorities and write improved standards, to improve compliance with existing standards, and to identify research needs. NIOSH analyzed 2075 bulk dust samples from NOHSM which yielded an average of 14% quartz (14808607). The data suggested that it is important to monitor coal mine occupations such as supply man and laborer on the surface along with metal/nonmetal occupations such as sizing and washing workers and bin pulley and truck loaders. The highest average percentage for quartz (22%) was found in surface pit coal mines. Of the 272,000 miners represented by the data of this study, 78,000 (29%) were potentially exposed to bulk dust containing an average of quartz greater than 12%. These workers experienced the highest potential exposures to bulk dust with average percentage quartz. The authors conclude that better regulations and control techniques can be developed for these workers based on these findings.
