[Labor conditions and morbidity with temporary disability in workers of the excavation teams engaged in the Karaganda open coal mines].

Studies performed at an open-pit mine in the Karaganda Region showed that excavator operators were exposed to the complex action of vibration, noise, unfavourable microclimate and dust in the parameters exceeding the existing norms. A comparative analysis of the levels of morbidity with temporary disability and the actual occupational conditions proved the latters' influence on the morbidity rate, particularly in case with diseases caused by respiratory infections, spinal disorders (radiculitis, lumbago), blood circulation dysfunctions, all of which should be attributed to occupationally conditioned ailments. Hygienic and preventive measures, with due account of specific groups of diseases, can considerably improve the workers' health status and decrease morbidity with temporary disability rates.
