“…A promising direction is acoustic monitoring. However, despite the widespread use of this method and its application in studying the physical and mechanical properties of soils [19][20][21], it is necessary to solve the transition from the dynamic soil deformation modulus to the general deformation modulus.…”

Much of the territory of the Russian Federation is located in the permafrost soil area. The developed hydrocarbon deposits make a significant contribution to the budget of the Russian Federation. Therefore, ensuring trouble-free operation of engineering structures and these fields is the most crucial task. Frozen soil deformation leads to violations in the operation of structures, which entail economic harm and significant environmental problems. This article provides a brief overview of the leading causes of deformations of engineering structures built on permafrost soils. The methods currently used to stabilize the frozen soil deformation are considered, and the directions for solving this problem are proposed.

“…Failure of one of these chines causes a halt in operation and a pause in the extraction process. Therefor maintain the continuity of operation, all of these machines must work without failur the same time, decreasing deposits and the need to reach for increasingly difficult deposits generates new problems and requirements for the machines and technolo used [35][36][37]. In the research area of coal extraction, the problem of adapting cu technologies and machines to new mining and geological conditions is resear worldwide [4,[38][39][40].…”

The underground mining environment is currently based on technology that uses mainly analogue sensors in machine and equipment control systems. The primary machine performing the most important functions in a mining system is the powered roof support. In order for it to work properly, it is important that it achieves the required power. To ensure this, it is necessary to continuously and precisely monitor the pressure in the under-piston space of the prop. Due to the extreme environmental conditions, pressure sensors should have high sensitivity, large transmission capacity, small size and light weight. To achieve these requirements, the authors of the article propose to implement a monitoring system based on photonics technology. To achieve this goal, several studies were carried out. The range of these studies included simulations, bench tests and tests under real conditions. The obtained test results showed the possibility of developing the control system for the powered roof support, the additional function to supercharge power. Based on the analysis of the obtained test results, assumptions were developed for the development of a power charging system with monitoring sensors. Based on the guidelines obtained from the research results, thedevelopment of the above prototype based on photonics technology is proposed.

“…The cutters operating modes determine the intensity and efficiency of the entire technological chain of mining at a mining enterprise [4][5][6]. The mass of the cutter is no more than a thousandth of a mining machine [7][8][9], but at the same time it is its main element, since its hardness, wear resistance and failure-free operation determine the efficiency and reliability of any downhole mining machine [10][11][12].…”

The main volume of coal is mined underground using shearers. In modern shearers, auger actuators are mainly used, which are distinguished by the simplicity of design, manufacturability and reliability. However, in the process of separating coal from mass by cutting, the yield of fine grades is 40-50 % of the total production volume. Therefore, the search and development of technical solutions that provide an increase in the yield of large fractions in the process of coal mining with auger shearers is an urgent task. Traditionally, this problem is solved by increasing the thickness of the slices, which is achieved by installing cutters with a larger radial reach and increasing the shearer feed rate. An unconventional way to increase the cross section of slices by forming energy-efficient paired and group slices with mutual superposition of stress fields in the mass from the action of neighboring cutters is considered. The results of modeling the process of cutting coal confirm that an increase in the efficiency of destruction of the rock mass by the cutters of the auger executive bodies of the shearer can be achieved by a complex technical solution, including the formation of paired cuts and combined stress zones in the rock mass. As a result, the output of large fragments when cutting with paired cutters increases by 1.3-1.8 times compared with cutting with a single cutter.
