[Hygienic evaluation of sewage from coal open pits].
The composition of open-pit, drainage, process, domestic sewages was studied in the stripping. They showed varying contents of substances and chemicals. The stripping sewage cannot be used for processing and agricultural purposes with pretreatment. A technique is proposed for local purification of open-pit and drainage waters before their mixing in the accumulator.
