[Physiological-clinical evaluation of combined impact of local vibrations, noise and warming microclimate on miners].

Chamber experiments covered 3 groups--miners of surface mine levels, those of the deep levels and examinees having no adaptation to mine--to evaluate combined effects of local vibration, noise and heating microclimate. Human resistance against the stated above factors appeared to be a nonlinear system. Induced by vibration and heating, divergent changes of sensitivity to vibration and dyastolic blood pressure appeared only in the examinees having no adaptation to mine, but not in the miners. The studied occupational factors were not antagonistic. The results obtained necessitate different regulation of microclimate for surface and deep mine levels, in order to consider adaptational peculiarities of miners.
