Abstract
Field measurements utilizing a seat pad accelerometer were made on 25 underground coal mining machines in order to quantify the vibration levels experienced by the operators. These data were combined with information on the statistics of the operating times of these machines in order to compare the operator's vibration exposure to the criteria of the International Standards Organization (ISO) Standard 2631, 'A Guide for the Evaluation of Human Exposure to Whole Body Vibration'. The comparison showed that about 30% to 40% of all underground coal mining machine operators can be expected to be exposed to vibration exceeding the fatigue-decreased proficiency criterion, whereas only 10% to 15% would be expected to experience vibration exceeding the exposure limit. The primary sources of the exposure are shuttle cars and possibly scoop trams. Detailed exposure statistics are presented, and the implications of the results are discussed.
