[The working conditions during the prototype commercial operation of continuous-output equipment in KATEK coal stripping and sanitary improvement measures].

Work conditions were analysed in workers engaged into realization of the new coal extracting line technology producing 5250 m3 of coal per hr in KATEK open-cast mine. Hygienic standards appeared to be followed mainly on the constant working places and in the mining machine cabs, but noise dust parameters were not evaluated in the transloaders, microclimate parameters of excavator and transloaders were not assessed during the cold season. High concentration of dust appear in the air due to mining machines cleaning with the pumped air. Workers engaged into the coal transportation and its intermediate storage appeared to work in more hazardous conditions. Sanitary measures are suggested.
