Abstract
This paper presents a portion of the results of an extensive Bureau of Mines study to assess the task illumination needs on mobile surface mining machinery. The intent of the research was to study these needs and the visibility requirements of machinery operators in performing visual tasks. Investigations were performed at 22 surface mining operations, coal and metal-nonmetal, within several mining regions of the United States. Visibility and illumination measurements were taken for 159 visual tasks on 57 surface mining machines including draglines, shovels, blasthole drills, bulldozers, loaders, haul trucks, graders, scrapers, and several service-type vehicles. This paper addresses only the results of investigations at surface coal mines; a subsequent Bureau report will present the overall results and recommendations of the entire study. Tables are presented that compare computed levels of luminance and illuminance for workers in the 25- and 50-yr-age groups. These tables show that illumination, and consequently, task visibility, could be improved. The paper also makes recommendations for improvements in illumination and/or task visibility.
