Environmental and logistical difficulties associated with obtaining whole-body vibration measurements from mobile equipment during operation in underground coal mines have hampered attempts to assess the potential vibration exposures associated with the use of such equipment. An alternative measurement technique was used to gather data from mobile equipment during normal operation at three low-methane coal mines and to estimate the possible magnitude of benefit of three control measures. 188 long duration measurements were obtained from shuttle cars (N = 142, median measurement duration = 3.2 h); personnel transport (N = 24, median measurement duration = 2.4 h); and materials transport vehicles (N = 22, median measurement duration = 1.8 h). Whole-body vibration amplitudes either within or exceeding the ISO health guidance caution zone were consistently measured. In particular, shuttle cars demonstrated whole-body vibration amplitudes which frequently exceeded the health guidance caution zone. The potential effects of roadway maintenance, decreased vehicle speed, and shuttle car seat replacement were found to be practically meaningful.

与在地下煤矿中操作期间从移动设备获得全身振动测量相关的环境和后勤困难阻碍了评估与使用此类设备相关的潜在振动暴露的尝试。一种替代的测量技术被用来在三个低瓦斯煤矿正常运行期间从移动设备收集数据，并估计三种控制措施可能带来的收益。从航天飞机上获得了188次长时间测量（N = 142，中位测量持续时间= 3.2 h）；人员运输（N = 24，中位测量持续时间= 2.4 h）；和物料运输车辆（N = 22，中位测量持续时间= 1.8 h）。始终测量在ISO健康指导警告区域之内或之外的全身振动幅度。特别是，穿梭车表现出的全身振动幅度经常超过健康指导警告区域。人们发现，道路维护，降低车速和更换穿梭汽车座椅的潜在影响实际上是有意义的。
