vibration measurement of coal mill body

CONTINUOUS MONITORING OF WHOLE-BODY

2020-10-3  Similarly, whole-body vibration exposures were measured at three low methane Australian underground coal mines, with measurements obtained from shuttle cars, personnel and equipment transport vehicles, a continuous miner and a coal tram. The majority of measurements taken exceeded the ISO2631.1 HGCZ (Burgess-Limerick Lynas, 2016).
