Abstract:
The conducted research and analysis of foreign experience showed that the most effective method of combating the adhesion of rocks to working surfaces is their lining with anti-adhesive and easily replaceable polymer plates. Thus, at the pelletizing plant of pelletizing factory of JSC Mikhailovsky GOK, as a result of the conducted research, the classification of polymer anti-stick lining plates (PASLP) was adopted, namely: PASLP HP (high pressure) SD (standard design); PASLP LP (low pressure) SD (standard design); PPFP IWR (increased wear resistance and impact resistance); PPFP HWR (high wear

Abstract:
Forming an important component of water conservation infrastructure, canal concrete linings are often subjected to damage to different degrees under the combined action of many factors (temperature, stress, water load, etc.) during construction or later operation. Here we explore the temperature and stress changes in the lining plate under different temperatures and water loads and determine the most unfavorable position (where the stress is more concentrated or the stress value is the largest) of the whole canal lining plate to provide guidance for the subsequent design, construction, and mai

Abstract:
Belt conveyors are widely used in mining industry in open-pit and underground mining for moving bulkload in horizontal and inclined directions to the sites of processing. In order to create the best conditions of frictional contact between a belt and a drum, various methods of drive drum lining are used. The main lining material is rubber of different grades, providing proper coefficient of friction of a belt with a drum (within the range of 0.6–0.62). A drive drum lining material must have high wear resistance, thermal resistance, mechanical strength, ability not to accumulate electric charge

Frost heaving damage of canal lining in cold and dry areas is one of the important causes of canal leakage. In this paper, based on the bending theory of thin plate, a mechanical model of canal lining under the action of frost heaving force is established and solved.

: In order to analyze the cause of water leakage in highway tunnels, the damage property of waterproof board in composite tunnel lining with concrete matrix defects under hydraulic pressure was studied using Galerkin method for plates with large deflection. The deflection, stress and strain of waterproof boards were calculated in the conditions of rectangular and elliptic boundary due to concrete matrix defects. First strength theory was used to determine the critical load of the board and the critical depth of the defect. Investigation results showed that the maximum principal stress generate

Abstract:
In modern practice, the ratio of the effective load and shear of steel friction joints is estimated based on the coefficient of friction and pre-tension of bolts. The coefficient of friction is determined experimentally by testing standard samples. A linear dependence of the effective load and shear is usually assumed. In order to develop more accurate models of bolted steel joints, it is important to understand the behavior of standard samples at the initial stage of loading. An experimental study was carried out on full-scale samples of friction joints of steel plates for compression. The te

The quality of the hot-rolled plate up to 36 mm thick was estimated by the percentage of rolled products, sorted due to the presence of a surface defect "Non-metallic inclusions", and internal defects, detected by ultrasonic plate control. The analysis of the data on the total sorting of hot-rolled plates demonstrated that the amount of sorting differs significantly on the melting from which each series of tubular metal casting commenced, compared to all the other melting in the series. The sorting of the sheets rolled from the metal of the first in a series of melting proved to be 1.9 times h

In the Nuclear power plant Krško, there are two single hull condensate storage tanks with floating diaphragm each containing up to 757 m3 of demineralized water. The main purpose of these two storage tanks is to provide a capacity of cooling water for cooling the reactor coolant system via steam generators with the use of auxiliary feedwater pumps. This is a very important function from the safety point of view and that is the reason that both storage tanks are listed as safety class 3 components. It is also possible to fill up the condensate system if other means are not available. Condensate

Abstract:
Steels for several applications, such as steel cord for tires and heavy plates, present severe hydrogen restriction in their chemical composition. However, the hydrogen content of the liquid steel usually increases during tundish filling. This phenomenon, known as hydrogen pick-up, occurs due to direct steel contact with humidity present in the lining refractory, ladle sand and atmospheric air. The present work investigated by means of an analytical mathematical model the magnitude of hydrogen pick-up promoted by steel-air interaction. The relative importance of this mechanism was evaluated co

In critical structures used elements consisting of anisotropic materials with concentrated force or moment applied to them are often found. In order to equalize the internal force factors, as well as to ensure the required strength and rigidity of the structure, in places where a local load is applied, it is necessary to strengthen the plate with a rigid lining (stamp). There are several ways to solve contact problems. The way seems simpler if it is possible to determine the exact fundamental solution (FS) for the plate. The exact FS significantly reduces the amount of computational work due t

When assessing the stability of the slopes of the banks of reservoirs and channels, the filtration regime that occurs with a rapid decrease in the water level in the upstream, which is due to the nature of the operation of structures before floods, discharges, emergency situations, is of particular interest. A change in the water levels in the upstream causes a change in the position of the depression surface and the parameters of the filtration flow (pressure gradients, filtration rates and flow rates) in the coastal massif. At the same time, unsteady filtration occurs in the coastal massif a
