Described are the problems of reducing of energy costs for mine dewatering constructions by reducing the excess pump pressure to certain tolerances. There is setting out an approach to determining of the required depth regulation of pumps at various ways of changing of supply and pressure of pumping units. Given are the dependences of the diameter of the impeller, the density of air-water mixture and the electric grid frequency in function of the excess pressure pump.
