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...
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 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...
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...
It is known that, despite the high accuracy of water balance forecasting, existing models such as AquaCrop, SWAP and HYDRUS do not fully take into account the relationship between water - salt balance and the effect of temperature limitations on root growth. M...
In this study, the physico-mechanical and thermal properties of polyethylene modified with zinc terephthalate were studied. The use of modifiers in the production of polymer composite materials allows for a significant improvement in the operational properties...
This article analyzes the effect of pressure (0.1 – 100 MPa) and temperature (20 – 250°C) on the properties of technological fluids (HCl, water) and reaction products ( 𝐶𝑎𝐶 𝑙 2 , 𝑀𝑔𝐶 𝑙 2 , 𝐶 𝑂 2 , 𝑁 2 ) during acid treatment of carbonate reservoirs. Studies sh...
The article presents the results of studying the conditions for well gushing in oil and gas condensate fields under development systems with priority oil extraction and gas cap gas conservation, as well as the joint operation of the oil and gas condensate part...
This article presents theoretical studies aimed at reducing soil compaction caused by the tires of four-wheel tractors used in vegetable cultivation and harvesting under the soil and climatic conditions of our republic. The paper describes the structural desig...
This study investigates the technology for obtaining a bioactive supplement from pomegranate peel (Punica granatum L.), a widely cultivated fruit in the climatic conditions of Uzbekistan. To maximize the extraction of polyphenols, ellagic acid, tannins, and ot...
The development of the multimodal transport system in Uzbekistan in recent years has been linked to the growth of freight volumes, the strengthening of intermodal connectivity, and the increasing demand for logistics services. Between 2020 and 2024, the total ...
Under the influence of the vortex zone formed at the confluence of two channels, sediments intensively settle. Taking these sediments into account, the hydraulic and geometric parameters of the flow are determined. The analytical solution shows that at the con...
This study focuses on the analysis of the control system for the roasting process of sulfide-containing products. The physico-chemical characteristics of the process are examined, including temperature regulation, oxygen concentration, and gas flow stability. ...
The near-wellbore zone of reservoirs of various types is characterized by complex physical and chemical processes that determine well productivity and the efficiency of stimulation methods. This study examines three independent directions of near-wellbore tran...
This paper presents an integrated analysis of geological field data and the current development status of the Shortak gas-condensate field. Through interpretation of hydrodynamic well test results, reservoir filtration parameters were determined, including the...
The article examines the problem of surface-wave propagation on a current featuring large-scale turbulence in flowing reservoirs. In the course of the research, a scientific analysis was carried out of the main factors influencing the processes of alongshore c...
The near-wellbore zone of reservoirs of various types is characterized by complex physical and chemical processes that determine well productivity and the efficiency of stimulation methods. This study examines three independent directions of near-wellbore tran...
The operation of BelAZ mining dump trucks in environments with high air dust concentration has a significant impact on the technical condition and service life of internal combustion engines (ICE). This study analyzes the interactions of dust particles with co...
This paper presents a modeling approach for acid treatment of carbonate reservoirs, taking into account the geological structure of the near-wellbore zone. Using real field data from the Matonat and Western Kruk fields, parameters such as the Damkyuler number,...
The basis of the system approach to safety management is the definition of the tasks of each element included in this system, the connections and interactions between them, as well as system analysis. The methods of system and system analysis, the Deming cycle...
