Applications of Noise Control in the Mining Industry

Jan 08, 2015 Noise may be generated by any number of equipment or processes required in the complex, dynamic environment of mining. This can include drilling, blasting, cutting, materials handling, ventilation, crushing, conveying, and ore processing (Donoghue, 2004).

Heavy Construction Equipment Noise Study Using Dosimetry

420,000 U.S. construction workers are exposed to potentially hazardous noise levels above 85 dB(A). (2) In the construction industry, heavy construction equipment is a major contributor to high noise levels at most job sites. This research was performed to identify the overall A-weighted sound levels of heavy construction equipment and the

Instantaneous Noise Survey Mining Health and Safety

Instantaneous Noise Survey. An instantaneous noise survey is used to document the operating noise levels for each piece of equipment. This helps a mine operator define any equipment that exceeds 115 dBA (a level to which no miner shall be exposed for any period of time per MSHA) as well as identfying equipment that might result in more exposure

Appendix D: Noise Exposures in Construction, Mining

Noise in Mining. Most of the of exposure to noise in mining comes from the need to use heavy machinery underground, but careful design and new technology and materials can be used to minimize this. Noise assessment in mining plants need to identify noise sources in order to effectively apply the hierarchy of controls.

To begin, noise levels must be determined at the locations from which the complaints arise. Once levels have been determined, the next step is to apply acceptable noise level criteria to each location and thus to determine the required noise reductions, generally as a function of octave or one-third octave frequency bands (see chapter 1).
