The article contains data on the evaluation of the physical and neuropsychic load, thermoregulation processes', CVS and CNS and neuro-muscular states in the workers engaged in ore crushing equipment service, in particular, in sand and gravel extraction enterprises in Tadzhikistan, USSR. It was established that the major unfavourable occupational factor lay in physical overload against neuropsychic strain resulting into marked changes in CVS, CNS, thermoregulation and neuro-muscular state. The contributors provided hygienic recommendation for labour conditions improvements.

The study was designed to analyze microclimatic conditions in the cabs of excavating machines and dump trucks during warm and cold seasons and to study their impact on body thermoregulatory processes in excavator and truck drivers. The study findings revealed that microclimate was especially unfavourable during a warm season. Inducators of body thermal state gave evidence that such working conditions generated stresses in thermoregulatory processes. Work during cold seasons caused some body cooling, especially at the beginning of the shift. The data thus obtained enabled one to elaborate health-improving measures aimed at optimization of workplace microclimate, rationalization of work/recreation regimen and drinking habits.
