Abstract
For deep coal mines, parallel operation of dewatering pumps on one pipeline allows to considerably reduce equipment cost and operation expenses, which provides reduction of total costs of water pumping. However, wide application of parallel operation of pumps is prevented by difference of their pressure characteristics during operation. The expediency of correction of pressure characteristics by means of regulation of rotation frequency of electric drives of pump units is considered.
