Abstract: The safe and effective hydro excavation and moving of overburden of old hydraulic dump for future exploitation of a part of coalfield lying under a hydraulic dump can be ensured by a hydro complex which combines in a single process chain the hydomonitor excavation of soil and excavation with a suction dredger. It is necessary to maintain certain parameters of the process of hydomonitor excavation to ensure the stable operation of such a hydrocomplex. Operational adjustment of the parameters of this process which is achieved by selecting the diameter of the nozzle of the hydromonitor, can change the force of hydro monitor jet on layer of soil and the performance by water and hydraulic mixture. An algorithm of determining the diameter of nozzles of hydromonitors which ensure the required parameters of jetting the overburden in consideration of the operating mode of the pumping station is proposed in this article.

Key words: hydro excavation and moving of overburden into the hydro dump hydrocomplex which combines in a single technological chain the hydomonitor excavation of soil and excavation with a suction dredger adjustment of the parameters of hydromonitor excavation determination of diameter of hydromonitor`s nozzle
