The objective of this study was to determine the magnitude and sources of environmental noise from mining operations near populated areas, to describe monitoring techniques, and to identify applicable existing noise abatement techniques. Noise surveys of a representative sample of mines and quarries were conducted and noise levels at site boundaries and near specific equipment and ensembles of equipment were measured. Noise exposures in terms of annual day- night sound level were calculated for the boundary noise measurement locations. In addition, the relative sound level contributions were estimated for the mining equipment noise sources affecting the boundary locations. Noise abatement methods falling into three categories were analyzed: equipment practices, operational- administrative practices, and equipment quieting. Selected applications of noise abatement methods were evaluated in hypothetical situations with emphasis upon machinery selection and use. Procedures for measuring noise around mining operations are provided.
