Abstract

G. Tsulukidze Mining Institute performed the fundamental studies of the operation of pressurized main water transport systems (slurry pipelines). These studies have been performed on both laboratory and semiindustrial experimental installations as well as on many large industrial systems. Based on these studies, it has been established that the efficiency of the studied systems is particularly increased by growing the hydro transmission distance of solid loose materials. This efficiency especially increases in the case of pulses when the concentration of loose solids in the hydro aeronautics in the pipelines increases. Because centrifugal ground pumps used for the transport of hydraulic mixtures develop relatively low pressures, the hydraulic transport systems studied are typically multistage. To do this, it is necessary to turn on the pumps in the main pipeline in sequence, or the main system consists of several separate systems, which complicates the operation of the system and worsens their technical and economic performance. Due to the peculiarities of operation, pulsed pipes are the most difficult, which lies in the fact that during their operation, hydraulic shocks occur very often, which has the worst impact on the efficiency of similar systems. Therefore, the schemes of multi-stage main hydraulic transport systems are discussed, equipped with such necessary devices which allow the sustainable operation of systems with maximum technical and economic indicators.
