The paper substantiates the application of the phase control of the multipolar equipotential electrical installation to improve the geodynamic sensitivity of the geoelectric control method in geodynamic and geotechnical monitoring systems. The principle of the control of the source of sounding signals and the detection of geodynamics of the geological environment is shown in article. In this work is proposed the device on base of the phase modulator to eliminate the shortcomings of existing devices of the controlling of the phase of sound geoelectrical signals. The developed device contains two amplitude limiters, the integrating unit, the adder, the master oscillator and the amplitude modulator. In practice the application of the proposed device allow to obtain the technical and the economic efficiency by simplifying of the circuit of the generation of the signal with the phase-modulation, by increasing the linearity of the modulation characteristic, and by generating of the signal with the phase-modulate on output of the device.

<p>The paper deals with the problem of ranking alternatives to geodynamic monitoring systems in the case of uncertainty of their implementation time. The problem is characterized by the fact that the choice of alternatives and the effect of it depends on the quality properties of the applied organizational and technical solutions, taking into account the time of implementation. The ordering of alternatives is proposed taking into account the uncertainty of the implementation time factors. Ranking is realized by comparing the trees of functional characteristics of alternatives taking into account the compliance of their characteristics with time-varying requirements. The scope of the proposed method is the choice of configurations of geodynamic monitoring systems with significant differences in the implementation time of alternatives.</p>

Actual geotechnical monitoring systems and models of geocryological processes are aimed at assessing and preventing hazardous dynamic impacts on infrastructure facilities in the Arctic and Subarctic of Russia. The level of methodological support and hardware development of these systems are insufficient in Russia in the context of a changing climate, growing environmental impact and decreasing quality of geological survey and design. Pore pressure is successfully studied at the sample level in the laboratory and in the field by using the static sensing method, however, the dynamics of pore pressure and the physical patterns of this dynamics in soil massifs remain studied inadequately. For theoretical reasons, pore pressure should change under the influence of processes associated with freezing and thawing, and, consequently, it should affect the intensity of gas hydrate dissociation as well as the mechanical properties of soils. The modern technological base provides new opportunities for the study of the pore pressure dynamics in the soil mass. This opens prospects for improving geotechnical monitoring systems for the protection of infrastructure facilities from adverse natural and man-made impacts.

In this study, applications of the Arduino platform in the mining industry were reviewed. Arduino, a representative and popular open-source hardware, can acquire information from various sensors, transmit data using communication technology, and control devices through actuators. The review was conducted by classifying previous studies into three types of Arduino applications: field monitoring systems, wearable systems, and autonomous systems. With regard to field monitoring systems, most studies in mines were classified as atmospheric or geotechnical monitoring. In wearable systems, the health status of the miner was an important consideration, in addition to the environmental conditions of the mine. Arduino can be a useful tool as an initial prototype for autonomous mine systems. Arduino has advantages in that it can be combined with various electronic products and is cost-effective. Therefore, although many studies have been conducted in the laboratory (as opposed to field tests), Arduino applications can be further expanded in the mining field in the future.
