Operating practices and resulting production from longwall faces are continually improving. Consequently, longwall operators are continually seeking to improve the dust control capabilities on longwalls. NIOSH has been conducting dust surveys at longwalls throughout the country in an effort to document the types of controls that are being used and to quantify the relative effectiveness of these controls. To date, surveys have been completed at longwalls in Alabama, Colorado, Pennsylvania, Utah, and West Virginia. In addition, NIOSH has been reviewing longwall dust parameters provided by mine operators to the Mine Safety and Health Administration (MSHA) to assess the status of dust control technology being used throughout the industry. Results from the underground dust surveys and information obtained from MSHA are summarized in this paper to provide an update on longwall dust control technology and practices.
