“…In the course of the work, all available factual materials (core, GIS data) on drilled and previously drilled wells within the studied region were analyzed and reinterpreted, with the clarification of lithological and paleontological features, with the establishment of the genesis of sediments and their transformation by secondary processes [16,17]. A lithological description of the core, a petrographic description of the sections, paleontological studies, chemical, litho-physical, etc.…”

This article presents the problems of guaranteeing high work productivity in the digging or cleaning of ditches and collectors, as well as the implementation of design indicators, as specified in the project, and measures to eliminate them using modern innovative technologies. Ditch and collectors work at the level of demand, improve land reclamation conditions, increase productivity and reduce the volume of additional earthworks, increase economic efficiency to high levels. The results of the conducted scientific research showed that during the construction of the open pit, the volume of earthworks was reduced by 15%, and the carrying capacity of the stream was increased by 25%. As a result, it makes it possible to increase the reliability and maintain the technical condition of using open pits.

The present study analyzes the effect of the pipe material type on the transient flow behavior in a pumping system due to an accidental pump shutdown. The material types addressed in this study include steel and High- or Low-Density PolyEthylene (HDPE) or (LDPE); involving elastic and plastic rheological pipe-wall behavior. The numerical solution is developed basing on the Method Of Characteristics used for the discretization of the Extended One-Dimensional pressurized-pipe flow model, incorporating the Kelvin-Voigt and Vitkovsky rules. Experimental data from the literature were used to validate the numerical solver. The proposed numerical algorithm is then used to investigate the transient pressure-wave behavior induced by the power failure to a pumping station composed of an inline connection using different pipe material types. The findings show the severity of such a scenario, in terms of the magnitudes of induced up-surge and down-surge pressure-waves. Furthermore, this research demonstrates that plastic pipe-wall materials allow for substantial attenuation of surge magnitude in conjunction with the expansion of the period of pressure-wave oscillations. The observed attenuation and expansion effects are also found to be highly dependent on the plastic material type. In this respect, the findings indicate that the (LDPE-Steel) piping system's specific layout allows for the best tradeoff between the two last effects.
