Measuring Noise from a Continuous Mining Machine.

PB83214890

Publication Date	1983
Personal Author	Bartholomae, R.; Kovac, J.; Robertson, J.
Page Count	26
Abstract	Noise generated by continuous mining machines in underground coal production is an important health hazard. Bureau of Mines Contract J0387229 covers investigation of this noise through laboratory tests of simulated cutting operations and through in-mine noise measurements. The results of these investigations indicate that coal cutting noise and conveyor noise are dominant sources of mining machine operational noise. Typical noise levels for both cutting and conveying operations are approximately 97 dBA (decibels A-weighted).
Keywords	Mining equipment Acoustic measurement Noise pollution Sound pressure Cutters Coal mining Conveyors Continuous mining machines Noise levels Mine safety
Source Agency	Bureau of Mines
NTIS Subject Category	48A - Mineral Industries 68B - Noise Pollution & Control
