Abstract.

Presently in Kryvbass by different estimation there are to 13 billion т  of overburden  breeds in dumps, and in tailing ponds – to 6  billion т wastes of enrichment of poor iron-stones. Last years all more active possibility of the use of accumulateds in dumps and tailing ponds mineral mass is studied. In fact  the depositories of wastes are the formed technogen deposits. In the article, peculiarities of calculation of the main pipeline geometrical and hydraulic parameters for hydromechanization technologies for development of man-made placers formed in the washery refuse storages are considered. It is shown that for the hydromechanization processes under consideration, operating modes of the pipeline transport plants depend not only on geometric parameters of the refuse storage, but also on hydraulic characteristics of the processes of pulp flowing in the main pipelines. Hydraulic characteristics of the fluid flow affect the loss of head in the main pipeline only when dike dam exceeds a certain height, which depends on hydraulic slope, that is, on the pipeline parameters, pulp concentration and its flow rate. On the basis of the conducted research it was established that in case of highly-concentrated pulp flowing, angle of the pipeline inclination does not affect the hydraulic slope. Therefore, in the regime of flowing of hydromixture as a heterogeneous fluid for such pulps, hydraulic slope is calculated in accordance with the solution of the Buckingham equation.  It is shown that for the examined technologies of the hydromechanization operation  modes of options of pipeline transport will depend not only on the geometrical parameters of depository of wastes but also from hydraulic descriptions of processes  flow of pul'p on highways.

By using the obtained dependences, recommendations and methods for calculating parameters of hydrotransport for highly concentrated hydromixtires can be elaborated, which allow designing of promising technologies for developing the man-made placers formed in the washery refuse storages.

Keywords: hydrotransport, waste depositories of enrichment, hydrosmixture, high concentration.
