“…There is also stratification of the gravel material in size, both in height and in diameter of the formed gravel bedding. Suspension of gravel material on the transporting route with the effect of corking, which requires additional time for its elimination, can be observed accompanied with the risk of formation of gaping cavities opposite the aquifer, which causes well sanding [8][9][10][11].…”

The purpose of the study is to develop a technology for fresh water treatment in deep hydrogeological wells with productive horizons represented by medium-grained, fine-grained, and silty sands by equipping their intake part with block-type inverse gravel filters. Experimental studies were carried out using provisions of the general theory of scientific experiment and the theory of random processes. A theory concerning the possibility of equipping the water intake part of hydrogeological wells, being more than 200 m deep, with block-type inverse gravel filters using the proposed technology was further developed. For the first time, the dependence of the maximum depth of transporting block-type inverse gravel filters on the length of their section, the mass concentration of a binding agent, and the ambient temperature was established. A scope of the proposed technology was substantiated. A range of depths for equipping with block-type inverse gravel filters depending on the mass concentration of a binding agent in the polymer-gravel filter element and the length of its section was substantiated.

Features of colmatation zones of a productive formation in terms of rotary drilling by drilling muds are considered. A brief analysis of the most popular decolmatation methods is performed. Special attention is paid to the decolmatation method involving implosion effect. An example of one of the existing installations is represented with following consideration of its application features. A new principally different installation, free from the disadvantages found in the available one, is considered; a patent for the installation is obtained in Kazakhstan. It does not involve tubing with its packer and wellhead sealing. It also does not require a compressor and its manifold. Characteristic features of the newly developed installation for creating implosion effect are represented; its operation at producing both single and any number of repeated implosion acts is examined. A mathematical analysis is performed to calculate the empty space limits required for the implosion effect by a criterion to prevent casing string collapse by hydrostatic pressure of the drilling mud remained in the annular space. An example of dependency of the maximum permitted length of empty space in the casing string on its mechanical strength and its wall thickness, calculated by means of a computer program, is represented.

“…The jaw crusher was modeled as a six-bar linkage to obtain a mathematical equa-tion representing the mechanical structure kinematics. It should be noted that the dynamic performance was studied for different structures containing various composite materials during the deformation and stress analysis [11]- [13]. A similar analysis was performed using seven bar mechanism [14].…”

Purpose. Current research focuses on studying experimentally various parameters affecting the particle size produced in a vibrating jaw crusher developed and implemented at Al-Balqa Applied University. The main purpose is to find the optimal conditions at which the jaw crusher under study works. Methods. The jaw crusher angle and rotating mass type are considered to study all particle sizes and reduction ratios obtained for three different motor operation speeds: 1500, 2000, and 2500 rpm. Coarse aggregate weighing 900 g with 26 mm particle size is fed into the jaw crusher, which produces several particle sizes (19, 12.5, 9.5, 4.75, and less than 4.75 mm). Furthermore, the mass of the particles is measured and the particle size reduction is calculated. Findings. It has been found that the jaw crusher angle, rotating mass type, and the motor operation speed play an important role in both reducing the amount of mass and reducing the size of each particle produced. In addition, it has been determined that operation at a speed of 2000 rpm provides a significant change in both mass and size reduction of each particle size considered. Originality. The originality of this research lies in its experimental investigation of the effects of various parameters on particle size reduction in a vibrating jaw crusher, as well as in the introduction of a new design that uses one motor to drive two plates operating at different speeds and in opposite directions. Practical implications. The findings can be used to optimize the design and operation of jaw crushers in various industries, including metallurgical, quarry, and mining industries, where these crushers are widely used. The results of this study can also serve as a basis for future research on particle size reduction in other types of crushers and milling equipment.
