Experimental studies and rationale for the use of jetting DG-300 on the cuts of Kuzbass

The results of experimental studies of the new jetting DG-300, on the basis of which set of generalized analytical dependency jetting resistance ratio of the diameter of nozzles used and developed an algorithm for determining the diameter of the jetting nozzles, taking into account the mode of operation of the pumping station. Application of new jetting improves performance and efficiency jetting.
