This paper discusses the global copper production volumes and the main types of rare and base metals mined in copper mines, the need to select the methods for separating rare and base metals from millions of man-made wastes generated during copper beneficiatio...
The study develops a conceptual model for integrating the organizational Trust Index and Safety Culture into the process of ensuring occupational safety at enterprises, and provides a quantitative and qualitative assessment of its impact on reducing occupation...
This study comprehensively investigates technological and technical solutions aimed at ensuring the stable operation of gas wells during the late stage of development of gas and gas-condensate fields with carbonate reservoirs. The interrelated effects of reser...
This study investigates the determination of the geometric dimensions of a local scour zone developing within a cohesive soil section downstream of a hydraulic structure. The influence of the main hydraulic characteristics of the flow, including discharge, mea...
This article investigates the determination of flow-induced shear stress in earthen channels and the assessment of non-scouring conditions of the channel bed. Shear stress generated by flowing water in earthen channels is one of the principal factors governing...
This article investigates the recovery of molybdenum and other valuable components from magnetic separation tailings. A two-stage soda leaching process was applied to the non-magnetic fraction obtained after magnetic separation, followed by washing of the resu...
This article investigates the impact of various planting systems and densities on the leaf formation dynamics of sweet potato grown in open fields and under film mulch in Uzbekistan. The research results indicate that the film mulch cultivation system accelera...
This paper analyzes the flow behavior of gas – liquid mixtures in pipelines and reviews modern approaches to hydraulic calculations of two-phase flows. The main hydrodynamic and thermodynamic factors affecting the transportation of gas, oil, condensate, and wa...
Reliable prediction of channel bed deformation is essential for the hydraulic design, rehabilitation, and operation of irrigation canals with weakly cohesive beds. However, the presence of both suspended sediment and a small proportion of cohesive material com...
This study presents a comprehensive three-dimensional coupled numerical model for a solar-driven desalination device incorporating a capillary-structured porous membrane (CPM). The governing equations - encompassing conjugate heat transfer, capillary-driven ma...
This article investigates the hydrological indicators of the Kamashi Reservoir and their impact on the meliorative condition of lands within its zone of influence. During the study, the reservoir water level, water storage volume, groundwater depth, and the so...
In tasks of identifying relationships between technological parameters of automated control objects, the capabilities of neural networks are used. One of the important problems considered in such identification tasks is the choice of the neural network archite...
This paper presents the theoretical framework and practical computational methods for estimating bed-load and suspended-load sediment transport rates in a trapezoidal open channel with asymmetric side slopes (m 1 ≠ m 2 ) on non-cohesive granular beds. Four cla...
This paper presents an improved numerical method for calculating water hammer in pressurized pipelines under conditions of flow discontinuity and volumetric cavitation. The physical nature of the water hammer phenomenon is analyzed, and the main factors affect...
In this article, the channel deformation processes in the Amu – Bukhara Machine Canal and the main factors causing them were identified through field investigations and hydraulic modeling. The research results showed that during the period from January to June...
This study investigates the dynamic adsorption of petroleum hydrocarbons in an organobentonite adsorption bed for the effective treatment of oil-contaminated water. Experimental investigations were carried out in a continuous-flow fixed-bed column system. The ...
Abstract. Cotton processing waste (husks and stalks) in Uzbekistan represents a significant renewable raw material for lignin production, the basis of thermo- and salt-resistant drilling fluid reagents. The choice of lignin extraction method affects its purity...
The article presents the results of practical work on the effective drilling of salt layers that form an aggressive environment and the qualitative reinforcement of well walls. The types, properties, and parameters of tommanage solutions used for geologically ...
The article presents the results of a 3D geological model of the Sherkent oil and gas field, created using Schlumberger’s Petrel software. The Sherkent structure was prepared for exploratory drilling in 2007 based on the interpretation of 3D seismic survey dat...
The paper presents the results of studying the fracturing and reservoir properties of rocks based on well logging data. Standard well logging methods (WLM – acoustic, neutron - gamma, gamma - gamma density, electrical and induction logging) were used to determ...
