A new way of dust suppression in open pits is suggested, based on water pulverization from pressure pipelines of water
drainage facilities. The elements of the dust suppression system have been examined, which are located along open pit
automobile roads. The article introduces the methods of detecting pressure characteristic of water drainage facility with
track water intake for dust prevention. Calculation of possible parameters of water drainage combined with the suggested
moistening system operation is fulfilled. On the basis of the obtained performance figures some recommendations on the
pumps selection are stated for open pit water drainage facilities with track consumption water flow rate in the areas of
roads moistening; conditions of these facilities rational use are also justified. It is shown, that capacity overstock of a pump
station under normal water inflows piping out to the open pit is an important factor for water drainage facilities effective
use to reduce air dust content.
Key words: opencast mining; safety rules; labour protection; poisonous gases; aerial dust; open pit roads moistening;
water drainage facilities; power water conduits; track water intake; hydraulic resistances; pressure loss; pressure
characteristic of a pipeline; pressure and pump capacity; normal water inflows.
