摘要

Miners at noncoal surface mining operations are often exposed to high levels of respirable dust. In an effort to lower the respirable dust exposure of these surface miners, the National Institute for Occupational Safety and Health (NIOSH) has been conducting research to address this problem in a practical and economically viable manner. This report focuses on two areas of research performed at the Pittsburgh Research Laboratory (PRL) to lower miners' exposure to respirable dust at surface operations. The first area deals with enclosed cabs. A significant number of miners work in enclosed cabs at surface operations, including drill, dozer, loader, and scraper operators, as well as a vast array of different haulage vehicles and trucks. Secondly, this report discusses methods to lower dust levels at surface drills. The dust generated during surface drilling exposes the drill operator, drill helper, explosive crew, as well as any other individuals working in and around the drill to high respirable dust levels. The intent of the report is to provide mine operators with a number of techniques to lower the dust exposure of workers at surface operations.
