ABSTRACT

Basing on physical model of heat exchange between human body and environment,
predicted thermal load under the work site parameters, specific for deep mines, was
defined in the paper. The relationships included in EN ISO 7933 standard were used for
this purpose. Level of heat accumulation, degree of skin moistness, maximum volume
of sweat and body dehydration were evaluated. These parameters we used to define the
safe time of work under difficult climate conditions. The calculations were made in
respect of acclimatized and not acclimatized workers and for different value of energy
performance.

Keywords: hot microclimate, safe working time
