This manual specifies standard procedures for gathering and analyzing respirable dust data. The procedures were developed based on experience from numerous field surveys aimed at evaluating respirable dust conditions and control techniques. The procedures were then successfully used on an actual field evaluation of longwall dust control using water sprays at a western U.S. coal mine. Although the manual focuses on standardized procedures for longwall production faces, the procedures can be modified and adapted for other mining systems, including continuous miner and conventional sections. The procedures can be applied to identify the primary sources of respirable dust on a particular face and to objectively determine the effectiveness of a particular control method under the conditions in the study area. The manual also suggests a general approach that will maximize the value to the industry of the data collected by independent researchers or mine engineers.
