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). For full operation of all machine systems, the overall sound pressure level is approximately 101 dba. In-mine and laboratory test results show excellent agreement in both a-weighted overall levels as well as in a-weighted one-third-octave band spectra.
