This report presents the reduced vibration data from 10 mining machines that were tested to determine the effect of underground environment and loading conditions on acoustic noise levels of coal mining equipment. Vibration measurements were obtained on machine locations where control or sensing electronics may be mounted. The measurements included vibration data in the 20- to 3,500-hz frequency range. The 10 mining machines include continuous miners, a loading machine, a coal drill, a roof bolter, and a 25-ton locomotive. A list describing the mining machine, geographic, test location, and test date is shown in table 1. The vibration data has been reduced to octave band, 1/3-octave band, and narrow band levels.
